Mystic 185 Twin Turbine Build by Chris "Sir File-a-Lot" Fischer

[ManuelW]

Hello Guys,

after the requests in the HPR 135 - German madness thread I decided to present Christians new build also here on OSE and translate the review.
I hope you enjoy the build, I think its very very well done and deserves respect even if its not a FE boat.

As there might be question: This boat is owned and re-built by Christian Fischer. But we work very close together and I also helped searching and purchasing parts as well as doing design work and CAD crafts....

HPR 185 - TwinTurbine project

Originally the boat was build by Chris Tonn. Beside the paint job he also did the big changes concerning the canopy of the boat. Now it features 3 independent hatches, the side hatches are scaled down from the real Mystic C5000R for the turbines. Then the boat was sold to a guy in the Netherlands.
Christian saw the boat at the annual powerboat meeting in Heilbronn and fell in love with it. As it was for sale a bit later he decided to buy it and in the middle of september last year Christian and I drove to pick it up. Both ways together were about 1530km to drive and it took us the whole day but it was worth the effort.

Basically the boat was RTR except the receiver and the two turbines were at JetCat to be checked and serviced.

Here a picture of Christian and his new beauty after returning home:

dismounting and cleaning

As some of you might already know some of his other boats he invests tons of work in little details and nice hardware of the boat. They call him "Sir File-a-lot" because of the excellent work he did with files and CF-sheets in his HPR 115 with the "2-Face" paint job. So the boat was already built but it was quite clear that he would rebuild many parts.
First of all he dismounted all the parts to clean and polish the bare hull.

Hello Manuel, I've been following this build on the powerboat forum using Google translate. Christians work is amazing. Everyone will really enjoy this build. I know I am. Thanks, Bruiser

rudder facelift

The original rudder is quite nice but Christian thought there are still a few things to improve. So he disassembled the rudder and built some parts again on his own little milling machine. Its a conventional one and not CNC, the fabricator is Proxxon. For the other parts he decided to polish them to perfect finish. The black screws are M4 and out of Titanium. The cover out of CF-sheet is 0.3mm thick. As its quite small, he pre-drilled the nine holes with 4mm diameter and then used some rolled sanding paper to get them to the precise final diameter of 7mm. Another change was that he changed the normal bushings of the rudder axis to ball-bearings. I think the rest is self-explained by the pictures. If any question arrives, feel free to ask.

The Turbines

A few weeks later the checked and serviced turbines arived back from JetCat. These turbines are the JetCat SPM5 marine turbines, each one can produce around 7kW output power at the shaft. Its a 2-shaft turbine like its used for a TurboProp. The first turbine runs at around 170.000rpm under full load. The generator part can run nearly at the same rpm. The second shaft is connected to a 3-step gearbox with an input of around 170.000rpm and an output shaft which runs around 28.000rpm.

Here some pictures of the babies:

[RaceMechaniX]

Manuel,

Thanks for translating and uploading the postss here. BTW, does Jetcat still produce the SPM5's?

Tyler

[nata2run]

I already wonder, what's next. Lol, I kinda just laugh/smile when I see Christians work. What else can you do.

[ManuelW]

Hi Tyler,

yes JetCat still produces the SPM5 Marine Turbine, at the moment its also the only company I know that still produces a marine turbine. I'd say the system is well developed now and due to increased production numbers they are even available for a lower price now (decided to write lower, as I think "cheaper" is not the right word to be used).

Best regards,
Manuel

[RaceMechaniX]

Thanks Manuel,

I did not see them on the JetCat USA site and wondered if they stopped producing them.

More masterful work by Chris. Always a pleasure to see what he comes up with. I think i may need to place an order with him. Grin.

They are making the mod 2's slightly better electronics setup wiring wise, i never liked the cable dangling from the top. I lost the warranty on both of mine due to making new second stage turbines for the tranny but they have stated they will work with me on price when it comes time to service them. Be careful how you mod them. Also if you are going to get a turbine do not use the screen type intakes they use as they are a huuuge restriction and allow heat build up in the engine due to restricted airflow, i use a couple turbo intake K&N filters rated at 50+ for air intake.

[ManuelW]

hopper tanks

As like in the original build, the fuel pumps are not fed directly from the main fuel cells but there is a hopper tank in between. This is mainly due to better/more reliable fuel supply of the turbines, as it is smaller and always full. The included one was made of GFK but as Christian works a lot on turning machines he decided to make a pair of hopper tanks out of high strength T6 aluminium.
Each tank is made of two seperate parts, they can be screwed together over a M75x1 fine pitch thread. I think this alone took quite some time to produce. On the bottom is a M5 thread for the Festo 90° angle which goes to the fuel pumps. On the top are three M5 threads, one for the intake from the main, fuel cells, one for filling the fuel tanks and the third one for a display tube which goes to the bottom. Otherwise you can't check the fuel stand inside the hopper tank as it is made out of Aluminium. For all threads Loctite 648 was used to seal them.
To make it even nicer he did some marquetry work with 3D optic CF sheets.

Here some pictures of the progress:

[ManuelW]

As I mentioned he needed some kind of display tube to show the fuel stand. You could just do it by using a clear tube which goes from the top to the bottom. But it would not be Christian if he did it the easy way. So he invested quite some time to do it as perfect as possible. It would be difficult to explain but I think its easy to see when you check the pictures.

For the final touch he found someone on the forum who does laser engraving. So he sent the hopper tanks away to had the skull from the paint job engraved on the top surface. Here some pictures of the final result.

WOW, I always love to read these threads although they sure remind me where I'm at with my building skills (lack of).

[cuppa]

That is a work of art. Many thanks for sharing it with us.

[Drax21]

This is great!

[Derrick Davis]

Dear Santa.....
Another thread where I'll be anxiously watching the progress. :popcorn2: Good stuff and thanks for sharing!

[graill]

Why the hopper tanks Manuel? They are not needed and in my opinion simply clutter up a beyond fantastic engine bay. I fully baffled my tanks, there is no problem with fuel starvation or not wondering if the pumps will get fuel as i have replaced the orings with the proper material, something next to no one does but should with these turbines. Methinks Chris loves to make things, BiggGrin. Glad to see someone finally putting aluminized fibeglass cloth/ceramics inside their hulls too. I had talked to a couple gentlemen a couple years ago and they used the word gaudy and unneeded, i disagreed. I am glad to see Chris knows the deal. Let him know i have a line on some small vented steel if he is interested, to cover the first stage, better than the solid slab of stainless they have wrapped around it stock, if anything i am sure he can improve or take that to the next level. :smile:

[Boaterguy]

I can't tell whether i hate or love this guy.
he does amazing work that far outstands anything i have seen before, especially his gold digger.
then again, he makes me feel poor and unattentive.

@ grail: You've got a long PM :D

@ the others: BIG thanks for the credits

And now let's continue with the build...

RC Box Mystic TwinTurbine

Welcome to the review about the build of the RC box. Its one of the parts were we worked really close together. Normally a rc box is not a very complicated part but everybody who knows Christian also knows, that off-the-shelf parts are not what he is looking for. So I think this could probably be the most advanced/complex RC box ever built. Also it was very nice to see how state of the art CAD software and Christians manual dexterity can work together.

the idea

Christian visited me at home and came with 2-3 sketches and a DXF file (a vector graphic format) on an USB-stick. The main idea was easy: The box should have the shape of the skull (same one which is laser engraved in the hopper tanks), at the end of the tooth it should be extended (see pict. 1). So overall this was the available data:

http://www.mb-forum.at/baubericht_hpr_135_christian_684.JPG

http://www.mb-forum.at/baubericht_hpr_135_christian_685.JPG

http://www.mb-forum.at/baubericht_hpr_135_christian_686.JPG

Picture 2 also shows, that the box should be seperated. The extended part is seperated and contains the servo with receiver and receiver battery. In the main box is enough space for the power supply (2S Lipo) as well as the electronics and the fuel system for both turbines. The box consists of several frames and a base plate. Each seperated part should have its own plexiglas cover. Then there should be another final cover for the complete box. It should have the same shape as the box and made of glossy CF sheet with the skull cut out of texalium sheet on it. Maybe difficult to understand from what I write, when you see the pictures it should be clear.

As a CAD program allows complicated designs it didn't took much time to decide that we'd need another frame. This would enable concealed plexiglas covers and give a nicer look.
Picture 3 shows the skull from the original file, for Christian it looked like vertically compressed. As my CAD program doesn't allow stretching of vector graphics, I used a picture to show how it should look like:

http://www.mb-forum.at/baubericht_hpr_135_christian_687.JPG

The skull was stretched to 117%, that gave the desired look. As the design was clear I could start with the CAD draft. Meanwhile I sent the vector graphic file to a friend who stretched it to me and sent the new version back to me. The draft of the RC box did take about one day work overall, then it looked like on the pictures below. As I wanted it as realistic as possible I also needed the CF look, but there was just no suitable material implemented in the program. So first I created photo textures of glossy CF and texalium, then I created new materials and imported them in the program. In the draft the bottom of the box as well as the inner walls had a texalium optic, but when building it Christian decided only to have the bottom of the box with texalium, everything else has glossy CF optic.

http://www.mb-forum.at/baubericht_hpr_135_christian_695.JPG

[ManuelW]

As a few might have noticed the skull still has the same shape of the compressed one. This was as I started my work immediately and received the stretched one at the end of the draft. Here the comparison, I think the stretched one on the right looks definitely better

http://www.mb-forum.at/baubericht_hpr_135_christian_696.JPG

The I showed my final draft to Christian and he fell in love with it immediately. Without the smallest thing he wanted to change I could continue. First enough material had to be ordered, one HUGE 3mm CF sheet with enough area for three complete frames, a thicker texalium sheet for the bottom, a thin texalium sheet for the skull and enough glossy CF sheet for the side walls and the final cover. As we couldn't get any thin texalium sheet in Germany/Austria we had to import it from Switzerland.

production planning

My CAD draft was already built together digitally from several independent parts. Therefore it was easy to make technical drawings and create vector graphics from the individual frames. So I put three of these frames as close together as possible so save the needed amount of CF sheet. As it should be CNC milled I added little "bars" to make it as easy to cut them out and there is no danger of distortion.
Also created another drawing with the shapes of the plexiglass covers, to have these cut out from another friend. He did a great job on these, instead of real plexiglass he recommended and used 3mm lexan sheets. It's the same material as used for auto bodys of rc cars at it is very strong and not as breakable as plexiglass.

http://www.mb-forum.at/baubericht_hpr_135_christian_698.JPG

CNC cutting

This job was done by a good friend of Christian, they used a 2.1mm solid carbide miller with special cut for CF I recommended. On the right you can see the huge 3mm CF sheet with the three frames. Each of the frames has a different "width" (10mm for the floor, 12mm for the bottom and 5mm for the top), on the left the bottom sheet and the glossy CF sheet for the final cover. There you can also see the little bars, Christian only had to remove these and do a little bit of grinding and trimming to get the final parts.

assembly of the different frames

In the two frames with 10mm and 12mm width, Christian drilled congruent holes and then counter bored them for the countersunk screws of the spacers.

As for sure Christian did some modification to the spacers to save weight and get a nicer optic, then he also polished them:

After assembling with the spacers he glued the 5mm frame to the top:

http://www.mb-forum.at/baubericht_hpr_135_christian_710.JPG

bulkhead and side walls or just "the seams"

The next work was to glue in the bulkhead to create two seperate parts, before "wrapping" it with 0.3mm CF sheet to create the side walls. A very important chapter in the rc box build are the epoxy seams. As resin he uses UHU Endfest 300, I don't know if its available in the USA, here you can get it really easy. To be honest, Christian reached an almost awful precise level to make these seams absolutely perfect. Its maybe even better than a machine could do it.
Therefore below are a few photos which should show the perfection. He uses mask tapes to cover areas from the resin and to get a sharp edge. He adds black epoxy color to the resin and the exact amount of thixotropic agent. As tools he only uses the wooden sticks from McDonalds, there they use them to mix coffee but I think this is more a hoax - their real use is to make epoxy seams. He always says it needs a lot of patience and a calm and competent hand. The resin mustn't be too liquid as well as not to viscous - you have to get the right point. Maybe in the future I'll take a little bonus video of him how he prepares and makes these seams.

The bulkhead and the seams - sit down and enjoy!

[ManuelW]

http://www.mb-forum.at/baubericht_hpr_135_christian_714.JPG

The 0.3mm thin CF sheet has a nice glossy side and a rough one. As 0.3mm is really thin, first Christian made one layer with the glossy side to the inside of the box, then another layer with the glossy side to the outside. So the overall thickness of the side wall is now a bit above 0.6mm which is enough. Before he ordered the needed CF sheet, I could measure the circumstance of the box in the CAD program. For the 1. layer its 945mm, the box has a length of 345mm and a width of around 200mm.

[ManuelW]

http://www.mb-forum.at/baubericht_hpr_135_christian_720.JPG

I think the following picture sums up the perfection, in this curved area he didn't even use masking tape!

http://www.mb-forum.at/baubericht_hpr_135_christian_721.JPG

As you could aready see the side walls are higher than the box itself. So first Christian cut it down rough and then sanded it to the same level of the frames. The texalium sheet on the bottom was glued last, as he needed perfect access to both sides to make his seams. Here some pictures of the temporary result:

http://www.mb-forum.at/baubericht_hpr_135_christian_726.JPG
(and yes the optic of the side wall looks also in reality totally unreal like on the second to last picture :bowdown: )

final cover

As already mentioned there should be a final cover for the complete box, also with the glossy 0.3mm CF sheet as well as the texalium skull. Sadly the imported texalium sheet from Switzerland was not opaque, so you would have seen the black CF sheed shining through. As a solution I had the idea to have the skull cut out mirror inverted of a silver self-adhesive plotter foil. This has two advantages, first the sheet is not opaque any more, second that Christian then can use the contour of the "sticker" to cut the texalium sheet.

Here the two sheets/foils (1x texalium, 1x plotter foil)

Christian told me it was an extreme effort and took a lot of time to cut it out and file it to the right contour as the material is really really thin and starts to flutter almost immediately. Therefore he always filed as beneath as possible to the edge of the table and move only small distances. But finally he managed it :cool2:

baseplate for RC box

Beside the RC box also the already shown hopper tanks have to be mounted inside the hull. In the original build Chris Tonn already designed a mount system for the old RC box which was longer. On one side it was just hinged inside a mount with hard rubber plugs and on the other side screwed down using two screws.
Christian wanted to use this system again so he designed a HUGE baseplate out of the rest from the nice 3mm CF sheet. The plate is 508mm long and 155m wide.

Here the sketch....

After the ground plate was finished, the hopper tanks were installed first.

And here with the RC box, the mount system is still missing

As usual Christian made the parts for the mount system out of high strength aluminium before he polished them to "bling-bling" finish

The result

RC box and hopper tanks finally mounted inside the hull. I think everyone to his taste, I think the hopper tanks don't mess up the engine bay but are a nice piece of engineering.

[ManuelW]

Hello guys,

first a big THANKS from Christian and me for all the credits. :bowdown:
Makes us really proud, as its even not a FE boat we are presenting here. Maybe we should consider also to translate some of the other reviews to english and present them here. But thats something for the future. :banana:

for now, I'll continue with this one!

@megalops: I'm working with Catia V5R18, its a great design software.

rigging of the rc box interior

As already mentioned in the beginning of the review the RC box contains a whole lot of components and even more cables and silicon tubes for electronics and fuel system. A part list as well as some pictures can be found in post #2 in this threat. Christian wanted a very clean and tidy look, it was not that easy. In the end he manged it but it took a lot of work and the RC box is quite filled as we designed it as small as possible (the original one had more than double the volume).

servo mount

One of the first works was to make a servo mount for the HITEC servo. Despite the small standard size its extremely powerful and has a titanium gear. The four braces are also out of T6 aluminium and polished. Even the four black screws are out of titanium and anodized, better not ask for the price...
The rest should be clear from the pictures:

[ManuelW]

making the LED boards and the ECU's a little "nicer"

As you could see each turbine needs an ECU unit as well as a LED board. On both is the original JetCat sticker in the typical colors. As they would absolutely not fit to the rest of the boat I gave Christian the hint to change it agains, not that easy to guess what, 0.3mm glossy CF sheet. Took him several hours to file them out, as he need some information about the right connectors he found suitable white rub-off letters. Every sign is an own sticker and just 2mm high, no idea how he got it that straight!

fuel pumps

He didn't like the original fuel pumps at all, neither the look nor how they were mounted. So he changed everything. First he removed the old shrink tube and put a new black one on them. This is mainly for insulation purpose, you have to be aware of static charging of the fuel. As the mount itself should be invisible he turned four kind of endbells out of aluminium, then polished them for sure. On the bottom is an M3 threat to screw them to the bottom of the box. Then he wrapped some 0.3mm CF sheet round the pumps and clipped one of the endbell to each end. But the are not directly screwed to the bottom, there is a 3mm CF sheet inbetween. He filed it to the right dimensions, it even follows the curvature of the pumps which you can see on the picture. Now each pump is a unit which can be easiily mounted or dismounted.

http://www.mb-forum.at/baubericht_hpr_135_christian_765.JPG

mounting the first parts inside the box

As there go some cables through the RC box Christian had to make some lead-throughs. He turned them out of aluminium material, both parts got a M14x0.7mm fine pitch thread so they can be assembled. The inner bore is 11.2mm, just enough for the data-cables which go to the turbines. On the box he made a 2.5mm bore and then used sanding paper to get it to the right diameter of 14mm. That takes him 1.5 hours but he says its the only way to get these bores exact in that 0.6mm thin CF material. For sealing he used silicone which is normally used for fish-tanks.
After that he mounted the ECU's, the LED boards and the fuel pumps. As the box is completely curved he made some kind of net to be able to place the components on both sides symmetrical.

mount for the fuel filters

Christian decided to use two fuel filters instead of one. Normally one filter is used between the fuel pump and the Y-connector. His are before the 2 magnetic vents, one for the cerosene for the turbine and one for the start/ignition system. Beside each other there was not enough space in the box so he aligned them vertically. So he made a few drawings of the mount first, then filed out the single parts before he glued them together. The filters are clipped in from the side and fixed by the nut on each end.
A few pictures show it probably better than I could explain!

http://www.mb-forum.at/baubericht_hpr_135_christian_792.JPG

mounts for the magnetic vents

Each turbine has two magnetic vents which control and regulate the fuel supply during startup and running. As it was done for the filters he also aligned the vents vertically by a special mount. This time it was made from a turned aluminium part (T6 7075 aircraft aluminium, polished for sure). A big aim he had was not a single visible screw. So first he turned two pins with one rounded end, then cut them into pieces. One step before that he drilled two precise 3mm bores, these had to be absolute exact as they were given by the vents. On the bottom part he made a countersunk for an M3 screw, he even had to reduce the diameter of the head to the minium of 3.9mm. In the top part are some M3 threads so he can assemble each unit from the bottom invisible. After some little polishing also of the vents he assembled it as a unit with the fuel filters. I think it looks pretty nice.

[metalsak]

fantastic work.....and as i m also in the machining job,one think comes to my mind (like asterix and ovelix)...maby, when christian it was a small children,he eat a C.N.C controler.... very good for my eyes to see yours building...greetings from greece,manuel and cristian.....

[ManuelW]

Hello Guys,

today a bit more about the progress of the RC box.

@ drwayne: That would interest me as well - already told Christian a few times to document it. But for the build up to know I'd say already around 150-200 working hours.

@ metalsak: Thanks, especially as you also work a lot in the machining job. Kostas sends me nice pictures from your work from time to time over Facebook. Always a pleasure to see.

more lead-throughs in the RC box

Beside the lead-throughs for the main cables between ECU and turbine there have to be a few more. So thats another load of work to to. To be exat:
-2x fuel input through the bottom of the box
-2x 2x fuel output through side walls (1x fuel and 1x cerosene start per turbine)
-2x rpm sensor per turbine
-2x charging link (1x 2S LiPo for turbines, 1x 2S LiFe for receiver)

For the fuel lines he used special lead-throughs availabe by Vario Helicopter. The are made of soft rubber and the holes have to have the right diameter to be sealed. If the hole is too narrow you can't put the fuel line through, if it is too big it is not sealed. So he pre-drilled it with a small bore and then used sanding paper to get it to the right diameter. The charging plugs for the 2S batterys are Multiplex MPX-System. I ordered Christian several of them from Nessel Elektronik, they are the only ones who have these in black and not in the usual green. Again the rest should be clear from the pictures. For sealing he also used a black colored silicone, normally used to glue fish-tanks.

http://www.mb-forum.at/baubericht_hpr_135_christian_808.JPG

2S battery for turbine ECU's

The turbine itself needs a 2S Lipo battery as supply - standard is a 3300mAh lipo per turbine. But Christian perferred a single 2S Lipo for both turbines. So I ordered him a 2S 5800mAh 30C lipo from turnigy, it was also confirmed by JetCat that it is enough. When I received it I checked the batterys and then stripped it and removed the original cables and the balancer cable. On each pole I soldered three 2.5mm² cable (high flexible from Nessel Elektronik), for the balancer a single 1.5mm² cable between the two cells. So each ECU has now its supply over 2x 2.5mm² cable and charging is over 2x 2.5mm² wire with the additional 1.5mm² balancer wire. As you can't connect these MPX connectors wrong I used black wires on both poles as it looks better inside the box. Then I used black shrink tube. That was the work from my side.

For mounting the lipo in the RC box Christian created some kind of extra box or cover for the lipo out of 0.6mm CF sheet and some little mounts out of Aluminium.

final wiring in the box

As for sure Christian wanted to align all cables and connectors as nice and possible. This also included nice soldering and the right shrinking on the connectors. There is very little space under the LED boards so he had to solder the cables in a 90° angle. Therefore normal shrinking was not possible but after a few tries he was satisfied with his work:

[ManuelW]

http://www.mb-forum.at/baubericht_hpr_135_christian_819.JPG

but still quite some work to do:

http://www.mb-forum.at/baubericht_hpr_135_christian_822.JPG

[ManuelW]

final RC box

To the end it was really hard to find place for all the cables as the box was really narrow. It worked but it couldn't be a smaller one. He also used a small mesh guard on many cables to give them a nicer look. He told me it was like a surgery to do that.

Here some pictures, first a few overall then detail ones:

http://www.mb-forum.at/baubericht_hpr_135_christian_831.JPG

What was still to do was the wiring of receiver battery, receiver and servo but compared to the other part that was a margin. He also installed an emergency cut-off to be able to disconnect the receiver battery from the receiver. Also the servo arm got some little carbon fibre upgrades. The receiver battery is a 2S2P LiFe 1450mh, I desoldered it to two independent but still parallel connected parts. There was just not enough space for a single block of 4 cells. He installed also a little board to be able to check the receiver battery voltage.

For today I whish you a nice evening,
Manuel

[metalsak]

hi guys.....the way of christians glueing,and working on resin reminds me some of the finest TIC welders on stainless steel....SUPER!!!!! he always find the difficult way to build.... both,you are very lucky,that you are friends,as in my mind,the one gives to the other. keep this fantastic work,always. me ,from my side,for sure i will be more good on my projects,as we look a ton of quality work......stelios

[millzee]

It's nice to be able to start my day by seeing your progress, it get's my mind working instantly, love it. Your a modern day einstein:thumbup:

[graill]

Simply awesome. The work is of the highest calibre. To be truthful, i cant wait to see how Christian and Manuel will top this build. :smile:

[ecomisky]

Impressive Sir!

[ManuelW]

Okay, today a little more progress

turbine frame structure

The turbines come with a nice aluminium frame structure when you order these from JetCat. Its strong enough, light, cheap to produce and also has a nice optic. But as you maybe found out Christian has a little obsession with carbon fibre :roflol:
I guess if he could afford, he would make almost everything including the furniture and the floors of his house in CF.

Here are two pictures how the stock frame structure looks:

http://www.mb-forum.at/baubericht_hpr_135_christian_841.JPG

http://www.mb-forum.at/baubericht_hpr_135_christian_842.JPG

http://www.mb-forum.at/baubericht_hpr_135_christian_843.JPG

http://www.mb-forum.at/baubericht_hpr_135_christian_844.JPG

So he came up with the question, if there's a chance to make a new frame structure out of CF. But there are two problems:
-heat: Most interesting is that not the turbine itself is the main problem with heat but the gearbox which is directly bolted to the ground plate and has a big contact surface. After a run it will have easily around 100°C so with standard CF sheets this can already be a problem. It could even be that the ground plate is already a kind of heat sink but we were not sure about that one
-brackets: On the side there are aluminium brackets to stiffen up the ground plate, so these are quite important. And its not easy at all to find suitable CF brackets, even more complicated if you need "good" ones which means good quality, heat resistant and stiff.

But already Obama said "Yes, we can!". So the first part was my task. I contacted Roman Kulossek from JetCat about the idea and he said if we find heat resistant CF material it is possible. Also the water and the cerosene cooling work well, the ground plate is not used as an additional heat sink. For the ground plates I ordered a suitable 3mm CF sheet, these are made of high-strength PrePreg material with aviation approval. They are pressed and tempered with 140°C so there should be no problems with that.
For the brackets I found a suitable supplier where I ordered 5 brackets, they feature a thickness of 2.5mm. Both, the sheet for the ground plates as well as the brackets, have a dull surface. This is due to the use of pressed PrePreg material. It might not have the glossy optic but it will be definitely stiffer and have more strength than a glossy CF sheet of the same thickness. I had all the material shipped to Christian and then he moved on with the work.

First he polished the bearing chair to a mirror-like finish:
http://www.mb-forum.at/baubericht_hpr_135_christian_845.JPG

[ManuelW]

The next task were the brackets in the rear of each frame structure. As you might see these are different but its not a mistake. This is due to the different turbines. One runs clockwise, the other one runs counterclockwise which needs an additional set of gears in the gearbox. Therefore the heigh of the mount as well as the output shaft is not the same for both turbines.

http://www.mb-forum.at/baubericht_hpr_135_christian_846.JPG

http://www.mb-forum.at/baubericht_hpr_135_christian_847.JPG

http://www.mb-forum.at/baubericht_hpr_135_christian_848.JPG

Afterwards he did the base plate and the side brackets. He was very surprised about the strength of the material compared to the glossy CF sheets he was used to. Especially the bores are not that easy as a usal drill gets blunt very fast. So he used a solid carbide drill, which worked very well. The side brackets are not only screwed to the ground plate with M4 screws but also glued with UHU Endfest 300 over the full surface. That means its like its a single unit which is almost impossile to break.

http://www.mb-forum.at/baubericht_hpr_135_christian_849.JPG

The last work were the plates for the bearing support on the front. To get the right thickness he glued several plates together, using also UHU Endfest 300. He also changed the shape to give it a nicer look, not that angular. So from now on just pictures!

Amazing. The amount of skill, imagination and neat, clean design in this project is way beyond anything I could ever hope to achieve. It is nice to know that engineering skills of this magnitude are alive and well!

[Gimp]

Pure insanity, bravo!

What step is next?

[ManuelW]

And beside the nice optic the CF frame structure has two other advantages. First its much stiffer than the original aluminium one, second thing is weight. Didn't believe it first but the difference is nearly 200g for each side, makes almost 400g overall.

main fuel cells

What a surprise, Christian also wanted to replace the plastic main fuel cells which came with the boat. Sometimes I ask myself why he didn't build a completely new boat instead of replacing almost every part on this one. But the glossy CF interior, the Aquamania paint job and the custom hatch system with the three independent hatches make this hull really special - something Christian likes a lot.
Once I've seen a 72" skater with twin turbines online and I remembered it had cevlar cerosene fuel cells. I knew these are mostly used in jetpowered rc aircrafts. Cevlar is used due to its wear resistance, this is very important in cases of crashs. Carbon might be very stiff but it will break almost immediately in case of a crash. Sure you could make the fuel cell thicker and stronger but weight is a big problem. Therefore the use cevlar.
So I contacted one of the manufacturers and after exchanging several mails he decided to make me two custom produced fuel cells in glossy carbon fibre. These were also the first he did in CF, but the result was great. It took several weeks and also was not that cheap but definitely worth the effort.

Here a few pictures of the two "drivetrains":

[Boaterguy]

beautiful tanks, but they seem a little small?

[graill]

Well, i had a couple hours of free time to work on my rig.......as i worked on it i kept seeing Christians build in my head. I went and made a loaf of bread instead. :lol:

[Boaterguy]

does christian have a job? or does he just get paid for this?

[ManuelW]

Christian has a regular job, building rc boats like this is just one of his hobbies and he does it just for himself.

Best regards,

Manuel,

Does Christian have the Lambo? That one picture that circulated a while ago of a guy transporting an HPR in a Murcielago.

[ManuelW]

Hello Guys,

@ Tyler and Drax: Sadly not even close to the truth. He only could afford to buy that MHZ 185 Mystic boat after selling his HPR06 "2Face" and his beloved full carbon Cervelo road bike (which he built up over a few years to its final configuration!). So far away of being rich and able to afford a Lambo....

As a car he runs an Opel Astra Estate Diesel, practical and economical.

What might interest you, he once built a 1:4 scale model of a Ferrari F1 car almost completely from scratch except parts like the tires, the motor or the differential. Took him I think 2 years overall.

For the picture of the Lambo: That was a HPR 233 and the car was a Lamborghini Gallardo Sypder - picture was taken in France. Its a group of guys who owns almost every E-powered HPR 233 woldwide. My latest info was, that they have at least running 5 (!) of these at the moment.

Best regards,
Manuel

Oh, so its kinda like what I do. If I need money for another project I sell things on. The 2Face was a superb build and I bet the bike was nice too. Hope he got a good price on the 2Face.
Didn't expect that car as its similar to what I drive, great for transporting boats in though. Just goes to show if you have a hobby that you love, all your moneys goes into it.

5 HPR 233s!!! and a Gallardo Spyder in france .....ummm Thierry Henry and friends :roflol:

[Punisher 67]

Unbelievable detail and patience to do it all - Thank you Manual and thank Christain for posting this - I would be very curious to see the machine shop where all of this is custom built .

[Boaterguy]

if he has a job, where does he find the time for this?
i'm assuming he doesn't have a wife because valentine's is tomorrow and nothing has slowed down.

[metalsak]

detail and detailed.....always happy to see both of you guys to work......something interesting to take the temperatures away from the carbon sheet,is something that we say 'mirror' in our construction job here (coffee roasters)....if you find a very thin super mirror inox metal sheet,and you keep 2mm air gap from carbon,and also 2mm from turbine,this will keep the temps in a very low number....you can (if the space is good) to keep the other piece of insulation,on the cf sheet,that i see.........(just my opinion ,manuel and cristian) but if i can help you just 0,00001mm long,i will be happy......thanks for the super post here....stelios

[ManuelW]

@ boaterguy: Wrong again, he's happily married and also has two children. Where he takes the time? Mhh I've asked the question already myself several times couldn't find an answer. I mean beside rc boats he still has other hobbies...

@ stelios: jep, thanks for the info about the thermal shield, already thought about that. The 2nd stage is already covered by a polished SS sheet. The test will show how everything works, I think even the little heat insulation on the ground plate is not necessary. Hopefully in a future not too far away Christian will start the turbines the first time.

@ Punisher: Is this a swashdrive with a 40.160 and a big NEU 22 in your avatar picture?

Best regards,
Manuel

[Punisher 67]

No Manuel its the HobbyKing jet drive - I have modified the pump somewhat or better put corrected the flaws and then machined an adaptor bracket to fit a 3080/7 and a schulze 40/160 . there will be a complete write up on this + a writeup on the HK jet drive probably towards the weekend . Here is a quick picture of where I am so far .

I do not want to dirty your thread but here is a quick look .

That jet drive is really nice.

[jcald2000]

Punisher, Be careful of the jet drive. Having raced a full size offshore jet boat it will cavitate the jet drive as soon as the intake sees some air and the revs will go though the roof instantly!!
We ran a rev limter on the big block, you should see a big block torqe the mount 2" inches each way when the rev limter kickedoff or on.

[Punisher 67]

Hey guys thanks for the kudos and advice much appreciated . I will dedicate a thread to the HK pump and this conversion by the weekend and I look forward to being hammered there - Out of respect for Manuel and Christian and this awesome thread please lets all stick to there topic .

Thanks ..............:wink:

[ManuelW]

Hi,

can't await the thread about this jet-unit. For Christians build, I'll continue with the review this week-end. Right now Christian is working on a new set of powertrimms. These will be HUGE...

Best reagards,
Manuel

[ManuelW]

mounts for the main fuel cells

Each carbon fibre fuel cell has a volume of 42oz for the cerosene fuel. Christian didn't want to mount them fix inside, he prefered to be able to remove them for cleaning and service at any time. So he made a quite similar system which we normally use for the lipo batterys in our FE-boats. The ground plate is made of CF, the rest are polished aluminium parts. Each ground plate is screwed to 4 little mounting posts, these are glued to the bottom of the hull using special fish tank silicone. Each of the four posts has a diameter of 22mm or nearly 1" so its almost impossible to get them out again - at least not during any crash. The other four posts are directly glued to the fuel cell. Now its like a little rail system. To secure it he cut out two little CF brackets and he uses some nice anodized nuts. I think it should be clear after viewing the pictures. The whole system itself is superlight, each fuel cell with its mount has overall only 147g.

front turbine mounts inside the hull

As already shown he used some cf brackets and hard rubber parts on the turbine mount. But there has to be a suitable counterpart inside the hull. These were made of aluminium but Christian was not very satisfied with them. The thing is, its almost impossible to make these out of CF. The bore is so big, the bracket would have to be much bigger to ensure that there is enough weave left. Otherwise it would brake easily. So he decided to make them new with a better shape and then polished.

On the right the old ones, on the left the new set of brackets:

[ManuelW]

making the data and power cables to the turbines a little nicer

Beside cerosene fuel the turbines also need a power supply for the cerosene start and the electric starter and a data cable to give information back to the ECU. Christian made both cables a little nicer using mostly shrink tube and mesh guard.

[ManuelW]

mount for the main data cable

He could make the power cables himself using the black MPX connectors and the flexible 2.5mm² silicon wire so he made it just the right length. For the data cable with its special connector this is not possible. Therefore it was quite long and a bit loose inside the hull. Christian didn't like that so he made a little mount of it. I mean its just a mount for a cable, a little socket and a cable strap would do the job - but thats not Christians style. What he came up with, is really a little piece of art. I don't explain it, just enjoy the pictures of the little...

Best regards and have a nice evening,

[ManuelW]

Hello Guys,

I got a few questions about the machines Christian uses. Almost everyone has huge very expensive CNC machines in the mind, but only a very very few parts were made on them. Most of the parts Christian makes on his little Proxxon milling and turning machine.

[nata2run]

Well, you dont get to be called Sir File-Alot for nothing :wink: I sure do best with a CNC. Place the raw material and walk off ...hehe. all respect for Christian and his skills.

[Punisher 67]

Thanks Manuel for posting that - I would love to sit with Christian with a beer and talk machining - the man has unbelievable skill


I sure do best with a CNC. Place the raw material and walk off ...hehe

Its not always that simple - I can walk away for a while with mine but not for the entire run

[centralrchobbies]

First post to this forum and making it a good one. Congratulate you on the best build I have ever come across nicely done. Are you painting the outside like the new JBS boat with the skull as well. Rick

[Chrisg81983]

Words can't describe this build he is very talented and thank you for posting this build

Chris

[metalsak]

AAAAHAAAA.........o.k very nice building..good skils...but we must say almost and for fantasy!!! this is very important,in construction,and a must when you build something,that never see before(and in that detailed way)...im not in my pc for long period,because of my job,but today manuel im happy because of the lathe and milling machine. for our main job,the C.N.C machines are just fine,but i understant,the hobby time,and the dificulty that you must have,in order to love,what you do..........for the friend that say that C.N.C is grate,i ugree but as i have say before: 'dont worry....cristian when it was small children,he eat a fanuc C.N.C controller'....(like ovelix comic) all the best,stelios

[megalops]

Man this beast has got to be done by now!. Hurry back guys - we need our fix!!

[brooks93]

holly crap what amazing craftsmanship.

[ManuelW]

Hello Guys,

tomorrow will be an update for the new drives, so just a little more patience....

Best regards,
Manuel

[ManuelW]

Hello Guys,

so now it is officially time for:

The Monster-Drives

Already last year Christian machined me a set of custom drives for my SAW HPR 135. These were intended for maximum stability and control at very high speeds so they were designed by form follows function. And the function was great, they performed excellent on the hull right as expected. :rockon2: Also Christian liked them, especially the look.

So as for his new hull, this Mystic C5000, he also wanted a kind of similar set of drives. Overall it took me about 15 hours of work just in the CAD program to design the drives and make the technical drawings. Did think a lot about how to make the dimensions and proportions right as these should also work on this hull which is not self-evident. Therefore I couldn't just scale-up the drives from my HPR 135 but had to make some changes and tricks to get it right. But I think it should be fine and they should work very well on that hull but the first test runs will prove.
The optic is definitely a sharp contrast compared to the rest of the boat but they have just the desired look. They are quite huge (overall length from transom to the DogDrive is 240mm or almost 10" :scared:) and look massive but without looking clumsy or unshaped.

So I gave Christian the drawings and he was very very satiesfied and started immediately to order suitable raw material. He used very high quality T6 7075 aluminium which has a very high strength. The round stock for the drive tubes had a diameter of 60mm so it produced quite a lot of chips to machine the drive tube out of it.

Here the comparison of the round stock with the hull and the technical drawing, I think it shows the dimensions in the right proportion:
http://www.mb-forum.at/baubericht_hpr_135_christian_896.JPG

http://www.mb-forum.at/baubericht_hpr_135_christian_897.JPG

At first he turned the side with the ball joint, followed by the other side with a 12mm + 0.01mm bore for the bearings:

http://www.mb-forum.at/baubericht_hpr_135_christian_904.JPG

Here the result after the turning process completed, and seriously, the drives have already the final length!!!
http://www.mb-forum.at/baubericht_hpr_135_christian_905.JPG

[ManuelW]

Now the really hard work started, the milling. The turning was done on a CNC machine, as especially the ball joint is almost impossible to do on a normal turning machine. But for the complete milling process, he did everything by hand on his little Proxxon machine shown in one of the previous posts. And he did also take quite some pictures as documentation.

First step was to clear the two side surfaces and the bottom as these were just flat surfaces:
http://www.mb-forum.at/baubericht_hpr_135_christian_906.JPG

http://www.mb-forum.at/baubericht_hpr_135_christian_907.JPG

http://www.mb-forum.at/baubericht_hpr_135_christian_909.JPG

http://www.mb-forum.at/baubericht_hpr_135_christian_910.JPG

Next step was the upper surface which was much more complicated. But I think it is not necessary to explain, just take a look at the pictures:
http://www.mb-forum.at/baubericht_hpr_135_christian_911.JPG

[ManuelW]

http://www.mb-forum.at/baubericht_hpr_135_christian_912.JPG

[ManuelW]

http://www.mb-forum.at/baubericht_hpr_135_christian_918.JPG

Then they were sanded with 800 grit to remove any marks from milling or the vise:
http://www.mb-forum.at/baubericht_hpr_135_christian_919.JPG

Another project were the gearboxes, as you might already know Christian likes to use vast amount of nice little screws. So thats how I designed the drive. As it really was a complicated part he finally decided to had it CNC machined by a good friend of him who also cycles with road bikes. I think this was the right decision, it might have been possible to do it on his little Proxxon milling machine but the necessary time and effort would be in no proportion to the result, furthermore we already know his skills so another demonstration is not necessary... ;-)

These are the gearboxes after he received them:
http://www.mb-forum.at/baubericht_hpr_135_christian_920.JPG

http://www.mb-forum.at/baubericht_hpr_135_christian_921.JPG

The rest of the parts including some special plastic washers he also did on his CNC turning machine:
http://www.mb-forum.at/baubericht_hpr_135_christian_922.JPG

http://www.mb-forum.at/baubericht_hpr_135_christian_923.JPG

[ManuelW]

When all the parts where basically "finished" he started the assembly and polishing work:

http://www.mb-forum.at/baubericht_hpr_135_christian_931.JPG

http://www.mb-forum.at/baubericht_hpr_135_christian_932.JPG

A still missing part is the upper support of the drive which is screwed to the hull. The first step was turning, the second one milling. As he has a dividing head this was not a big deal - as for sure also done on his little Proxxon machine:
http://www.mb-forum.at/baubericht_hpr_135_christian_933.JPG

http://www.mb-forum.at/baubericht_hpr_135_christian_934.JPG

[ManuelW]

http://www.mb-forum.at/baubericht_hpr_135_christian_936.JPG

Next work was to drill twenty 1.6mm holes in the two cap nuts for the drive. Sadly this time he had bad luck, after 19 of 20 bores the 1.6mm drill gave up and broke. So he had to make this part again but then everything went okay for the second try. Here some pictures to see the work and the dimensions:

http://www.mb-forum.at/baubericht_hpr_135_christian_941.JPG

[ManuelW]

After drilling the holes and cutting the threads he grinded the parts like the drives with 800 grit and polished them to a mirror-like finish:

http://www.mb-forum.at/baubericht_hpr_135_christian_946.JPG

[ManuelW]

As you might have seen on the gearboxes there is a little circle with a diameter of 10mm. So he took some effort to cover it nicely with glossy CF to give the gearbox a nicer look - I think this can be called a win. To get a precise circle with 10mm diameter he turned himself a kind of stamp and used his vice. The CF sheet has only 0.3mm so it was not a big deal.

http://www.mb-forum.at/baubericht_hpr_135_christian_950.JPG

[ManuelW]

Some of you might remember, Christian had a skull lasered on his aluminium hopper tanks by his friend Hannes in the German Forum. Their work was beautiful so it was an easy decision to send them the gearboxes and the drives for a little "update".

Here you can see the result, definitely worth the effort:
http://www.mb-forum.at/baubericht_hpr_135_christian_951.JPG

http://www.mb-forum.at/baubericht_hpr_135_christian_956.JPG

[ManuelW]

Did forget to mention that, normally polished SS screws look beautiful but in this case there'd have been no contrast between the screws and the polished parts so Christian ordered some glossy black SS screws for the gearboxes and the drives.

Here two pictures I liked very very much, the comparison between my CAD drawing and the result:

This boat, the time and effort invested in it, can not be topped!! I can't imagine what that would look like? :smile:

It's just......perfect....

[sailr]

Wow!

[Drax21]

The amount of screws amazes me. A fair bit of loctite:lol: A world class build. I must say very good work on CAD Manuel, and the production of the drives by Christian is once again precision taken to a whole new level. The finishing touches with the polishing and laser work really completes it.

[megalops]

What!?!? Those drives are off the chart!

[Chrisg81983]

Once more I am speechless the amount of detail is just amazing

Thank you

[JCAustralia]

This is like jewelry making.

i am speechless......

[graill]

Which museum was this being made for again? :biggrin:

[ManuelW]

First of all a little picture in between:

Visited Christian to look for an update and pick up some parts but no one opened the door. But I could see lights inside and also hear some noise. So I walked round the house and found Christian sitting on the floor absolutely concentrated polishing his drives. Watched him a few minues, then I took a photo before I knocked on the window. He liked the photo and also told me to put it online. Because it shows that what we do here is not pressing the green button and the finished part falls out of the machine but its mainly just a real lot of manual work.

Mounting of the drives

Next step was to mount these drives on the hull. There he had some minor troubles as he didn't like the optic of the mounting surface inside of the hull. So he made a sketch on cartrigde and then cut out some nice CF sheet and glued it in using epoxy resin. He also prepared some selfmade aluminium washers which he polished for the screws to mount the gearbox as it is a seperate part.

[ManuelW]

http://www.mb-forum.at/baubericht_hpr_135_christian_968.JPG

Another problem arrived when we found out that the transom of the boat was not 90° to the last running surface. This caused a problem as the part where the drive is fixed on the transom had a negative angle and its end was below the tearing edge of the boat. So this would cause quite some drag and also lift. But Christian had a brilliant idea to solve this. First he cut out a piece of sanding paper in the form of a washer which he glued to that part that is screwed to the hull using double sided tape. Then he grinded a kind of countersunk up to 3mm in the transom. When finished he cut out a ring of 2mm CF sheet and glued it into that countersunk using an angle to make it rectangular to the last step.

http://www.mb-forum.at/baubericht_hpr_135_christian_971.JPG

http://www.mb-forum.at/baubericht_hpr_135_christian_972.JPG

Then he could finally mount the drives. I may excuse for posting a lot of pictures now but they all look good and it was almost impossible to choose the best ones!

The Props are a pair of PropShop 6518/3 in Stainless Steel reduced to 62mm in diameter. These are the perfect high speed props for that hull with that setup.

Unreal!!! .....

[Drax21]

I'm really looking forward to the first run!

Hello Guys,

thanks again for the Kudos!! Only a few minor things to do, especially the stuffing tubes and then you can expect to see a video of the first start of the turbines.

Best regards,
Manuel

[J.M.Fangio]

Nice works ! :thumbup1:

Manuel Im new to boats so I dont know much but after looking at this project and the attention to detail on this is beyond imagination.

[Chrisg81983]

Hello Guys,thanks again for the Kudos!! Only a few minor things to do, especially the stuffing tubes and then you can expect to see a video of the first start of the turbines.Best regards,Manuel


Can't wait to see this thanks a lot
Chris g

[Espresso]

Excellent build and thread showcasing the process. Curious though. If he had to place a price on this build, how much would it be? Lots of custom and fine detail you don't even see on a full size boat which makes it even a more impressive build.

[Derrick Davis]

Hello,
Is there video of this beauty on the water yet? Did I miss it somewhere else here on the forum?
Can't wait!

[dont slow down]

GREAT build, attention to detail, quality and engineering is beyond incredible. If I had the time, money, machinery, and talent to build something like this I would. Can't wait to see some videos!!! I'm curious (I'm sure everyone else is too) as to what the total cost is at right now?

[ManuelW]

Hello Guys,

its really always a pleasure to read the comments and Christian told me to forward you his greetings!!

@ Derrick Davis: No, there is no video available yet. We already startet a turbine but we want to take a few more shots and videos to edit a nice video.

@ Espresso & dont slow down: Its really difficult to tell and also Christian doesn't know either. I just can say that 2 years ago the same boat (MHZ Mystic C5000) with basically the same setup (2x SPM5 Marine Turbine), well built and a nice paint job was sold for 18.000€ which is around 24.000$. Most expensive parts are probably the turbines, each one is around 5300$.

And here some further progess on the build as Christian still has to do some minor jobs.

stuffing tube support

Right before the turbines there needs to be a support for the stuffing tube as well as a bearing to support the flex shaft. Normally not a big task but it wouldn't be Christian if it was normal. So he came up with quite an extraordinary creation. The main part is made of T6 7075 Aluminium turned to the right shape and then milled on his little Proxxon machine. It has a collet for the special stuffing tube on one side and a bearing sit for a ball bearing on the other side. From the top side he made three bores, two to mount it with hex socket screws to the bearing support on the turbines and a third one to oil/lube the flex shaft between the bearing and the stuffing tube on the other side.

As for sure he also polished them to a mirror like finish.

Here a few photos from the design process to the result:

http://www.mb-forum.at/baubericht_hpr_135_christian_999.JPG

[ManuelW]

But from beginnig he planned to make some kind of cover plates for these, thats why in the picture of the design sketch you can also see the skull.

The biggest task was to cut these skulls out of 0.3mm thin texalium sheet. The main outline was no problem as well as the eyes, he filed them right. A big problem were the individual teeth. He first tried with a superthinn diamond cutting wheel but it failed and he had to start again. The solution was to make a first cut with a scissor and then insert some 800 grit sand paper and file it till the gap had the right width. Now these got absolutely perfect.

http://www.mb-forum.at/baubericht_hpr_135_christian_992.JPG

http://www.mb-forum.at/baubericht_hpr_135_christian_993.JPG

Then he made a kind of "background" out of glossy 0.3mm CF sheet, quite an easy task for him.

http://www.mb-forum.at/baubericht_hpr_135_christian_994.JPG

[ManuelW]

For easy access he installed some supersmall hinges which needed M1.2 screws and therefore also M1.2 threads. These screw taps already almost break when you just look at them.

http://www.mb-forum.at/baubericht_hpr_135_christian_998.JPG

On the aluminium part he installed also some self-adhesive velvet for better optic:

Here the result outside the boat:

http://www.mb-forum.at/baubericht_hpr_135_christian_1012.JPG

[ManuelW]

prop shafts + DogDrives

Next task were the DogDrives and the prop shafts. I sent him some CAD drawings from both parts, he made the propshafts 1:1 the same, for the prop shafts he preferred to make them with a conus. More effort to make but it looks better.
For the propshaft he used some hardened and grinded 8mm shafts. They are very hard to machine with a surface hardness of 60HRC and Rp0.2 above 600N/m². The DogDrives are made from absolutely stainless V4A material.

Not much more to explain for these parts:

[Clueless1]

Done yet?:olleyes:

[ManuelW]

Hello Guys,

yes its done and also the 1st test run was successful. A full video is still in progress but I think you'll already like the following video:

http://www.youtube.com/watch?feature=player_embedded&v=JtYjdBBB2rs

It was taking at the meeting in Krieglach (Austria), it was a pure FE meeting so Christian just took the boat with him for show purpose and not for running. Its also a MHZ Mystic 1850 and not a HPR 233 as mentioned in the title.

regards,
Manuel

[dont slow down]

What video?

[Prop-a-Gator]

Didn't anyone ever tell you it's cruel to tease, Manuel? :wink:

[dont slow down]

Haha didn't mean to tease, couldn't see the video. So what kind of fuel are you using? Jet A?

[Prop-a-Gator]

Haha didn't mean to tease, couldn't see the video. So what kind of fuel are you using? Jet A?
@DSD: Tease Manuel all you like! :tt2: We all want to see it running. I was referring to him showing us a video of the boat spooling up on a stand = tease.
@Manuel: Seriously speaking, still very cool - even standing still. Everyone was very casually looking on in the vid. Tell the truth. It was earsplitting loud wasn't it?!?

[ManuelW]

Hi Guys,

@ dont slow down:
Here the video just as a link to Youtube: http://www.youtube.com/watch?feature=player_embedded&v=JtYjdBBB2rs
You can run these turbines on various fuels, like cerosene Jet A1, petroleum & even high quality diesel oil (here called Shell V-Power). Right now Christians turbines run on petroleum as it has the same performance but less smell than cerosene.

@ Prop-a-Gator:
Well a little teasing is always good - be sure as soon as we have an appropriate running video of the boat we'll present it as for sure also here on OSE. Up to now we only had the maiden run which was very short and not worth to presented alone as video. So we are planning another few runs next week and if the weather stays fine you can expect a video next week-end. And yes, its earsplitting loud....

regards,
Manuel

[Espresso]

So how many boats does Chris have currently and does he keep all these high end builds? A pic of his collection would be awesome.

[Chrisg81983]

Very cool sounds great Manuel I will get back to u real soon on what we were talking about I think it's definitley a go thanks for that info by the way
Talk to u soon
Chris

[Eric Ho]

Please congratulate Christian on an exceptional build, keep us posted on more!

[metalsak]

hi manuel and cristian....sorry for i dont reply for a long period,but here is a tons of work on our daily job...(madness)...i just see the drives....i want to be there,on the milling machine ,with you guys!!!!!!!! wow!! detailed work. very nice photos from machining (you understant why i love them). a big problem for me ,when i make a boat with tons of work,is that when i finaly get my futaba in my hands,is always a perkinson moving on hands,and a heartbeating like a piston on racing engine.....is there a medicine for this???xaxaxa.....i hope cristian to not have this problem like me...and for the video, i prefer a video ,that is quite good,as the boat building,so please not hurry up. must be A VIDEO!!! for this boat...i cant say nothing!!!! you make something VEEEEERY GOOD! i hope the best,and always be together you two,as this result,in my mind,is a result from two clearly minds,with the perfection in front. all the best from me.stelios.

[mejson]

I'm speachless! it's a breathtaking experience to see something like this...congratulations and best of luck in running this perfectly made monster!

VERY NICE MANUEL!!! i think that cristian sleep with a huge smile in his face....nice video,nice perfomance,nice friendship between you two....i think that this monster needs biger lake to get the max rpm,and top speed....(in run 4, is that you , on drive??????) i get neurous on the corners ,on lake ends...pfoyoyoy....(im still) grate job manuel!!!

[ManuelW]

Hi Guys,

@ James:
I think that was just the audio, so far after reading out the data after the runs everything was almost perfectly synchronized. At the moment we just have a little issue with the bearings but the boat itself is working excellent.

@ Stelios: Yes, Christian and I will continue to work together for sure. In run 4 thats also him driving. Was also surprised how he ran the boat but best part was when I actually sent him the video and he was shocked himself how fast he drove that boat :thumbup1:

So except a few more running videos and photos in the future not too far away!

regards,
Manuel

[nata2run]

Manual, with such a boat it's really not important how fast she was, however from the bushes I couldnt see clearly, so what would your guess be? She looks impressive regardless.

[Cervelo]

Hello Guys,

I'm Christian "Die Feile" Fischer - the owner and builder of the Golddigger and the Mystic AquaMania TwinTurbine of this thread. Manuel is sitting next to me and helps me writing this post in english. I can speak or write hardly anything in english so I'll also write my further posts in german and hopefully Manuel will always chime in and help with a little translation. But I'm very happy with the reactions to this thread, you are also awesome guys.
Manuel also showed me a few other threads here on OSE and told me its absolutely worth to register.

For my person:
As said my name is Christian Fischer and my hobby are rc powerboats. My other hobbies are my little dog Jamie and I also cycle a lot (mainly road but I also have a mountainbike) - so some of you might know the brand Cervelo which I've chosen for my username. I really started this hobby with the HPR 06 BudLight which I bought completely RTR from my friend mudl (he's also registered here) and then I rebuilt the interior. After that I built another HPR06, the 2Face followed by the HPR 135 Golddigger. My latest and by far biggest project is now the Mystic 1850 TwinTurbine from this thread. It is really a dream which became true with that boat.

So I wish you a nice evening!

regards,
Christian

[Prop-a-Gator]

Hello and welcome Christian! You are already a bit of a boat building legend here - before even joining. I have seen many threads link to your builds. They are astonishing in the level of craftmanship and detail. Your input would be a great addition to the forum.
:beerchug:

[Chrisg81983]

Thankyou for the amazing builds and it's great to have both Manuel and yourself on the forum

[Clueless1]

Welcome Christian!

Thank you for sharing your builds with the FE world! Truly amazing builds!

Best regards,
Todd

[megalops]

Welcome Christian - and again great build. Your like the "European West Coast Customs" of Rc Powerboating. LOL Enjoy the site.

[nata2run]

Willkommen im Forum Christian, wirklich eine Freude, Sie hier zu haben. (that's about as much German I dare to write) how ever I do spend a bit of time on the German forum's as well.
You have been a great inspiration for all my builds, (they slowly start to look like yours LOL) and set a standard for what a "high profile" model should look like. Don't be a stranger on this forum. If English is a problem, I'm happy to exchange for some building lessons ....

mit besten Grüßen
Kent

Welcome to the forum Christian
Thank you for posting your twin turbine build on this forum for us to enjoy. Your craftsmanship is absolutely astonishing. Also thank you Manual for taking the time to translate so we could follow along.

Hi Manuel, Christian..

Unbelievable build!
I remember this boat when Chris Tonn first put up Video of Turbines flaming whilst sitting against dock.
You truely have transformed what was already a magnificent boat to a OUT of this world #1 Scale boat in the world!!
I will go and work on my RADEK/HPR 233er today, and take some of what ive learnt from you and try to apply it to my boat.
Only wish i had the brain, skills, to execute some of the idea's i now have in my head :(
Cheers from
Australia

[ManuelW]

Well interesting to hear about your project, will await you starting a building review about that boat?

regards,
Manuel

[Eric Ho]

Manuel, Christian, thanks again for sharing this.

Great build, I have also been following the build on the German Powerboat forum, I remember Christian had also modified the water intakes and added a pump system, how did that work out?

[SAW- USA]

I've also followed this " rebuild" and I can't even think of a word or words to describe this build . I've tried to think of something but I just can't do it lol. I'll just say this " unbelievable " !!!! I know your not trying to kill the boat but what speeds have you been able to achieve ? I'm just curious as to what this build is capable of running ? Again very nice and congrats on an unbelievable build .

[ManuelW]

Hi Eric,

yep but so far he did not finally add the pump system within the boat. Instead he made a set of additional water intakes in the last step and added them with the rudder intake via two Y-harnesses to cool both gearboxes. So far it seems to run fine.

Here a video of what we did in Heilbronn:

[nata2run]

Christian, was its das?
What is it?

[Chrisg81983]

Kent I think a pump of some kind Maybe for constant cooling

[nata2run]

Maybe it's a coffee machine hehe, what else could this boat need?

[Gerwin Brommer]

pickups for watercooling ?

@ Manuel :

Nope, no more rc-boats for me. The only boat I would consider working on, would be 1:1 wooden raceboat ( Google for Flyer 15 hydro )

[graill]

If it is his turbine it is the pickup for the transmission cooling. He has obviously opted for a constant pump instead of the traditional forced system.

[nata2run]

hmm, the "picture filename" does say HPR_135 but he posted in this thread......I still think its a filter system for the coffee machine LOL, you watch! next there will be a nice chrome polished tab :)

[ManuelW]

Hello Guys,

Christian tried to upload the pictures in usual size but seemed to have some troubles with it. Next time I give him a visit, I'll explain it to him. For today I'll continue the thread here.

What Christian wants to show here is what some already thought, additional cooling for the gearboxes/transmission. So far both gearboxes got their cooling water from a single intake in the rudder blade and a Y-connector. First step was to make new intakes in the last step of the boat close to the tunnel. These pictures should be pretty self-explaining.

Next task was to create mounts for the pumps. These are rated at 12V and will be powered by a 3S lipo. They really create a huge waterflow and also some serious pressure. Completely made in germany with fibre reinforced casings and rubber bushings - makes them very silent!
It wouldn't be Christian if the parts were not completely custom made (cut, filed and sanded) out of glossy CF sheet:

As I already wrote, both pumps will be powered by a single 3S Lipo with 2800mAh, lasts easily long enough. The switch he installed inbetween is a magnetic switch from the german manufacturer Emcotec. On the outside you just need a little bore for the status LED, the pumps are shut on or off simply by holding the magnet either on the left or on the right side of the status LED. It works up to a distance of 1/4" so way more than a hulls thickness.

But also the battery itself needed a kind of mount, he decided to place it within the hatch and created a mount very similar in terms of optic to his RC box. Its made out of texalium and CF sheet, with aluminium spacers and anodized screws. I could go into details step by step how it was done but I think also this time pictures should be quite self-explaining.

The sheet on the left is glued to the inside of the hatch, the rest of the mount can be disassembled.

Here you can see in the middle the status LED of the Emcotec switch, he turned a little aluminium spacer for it which he polished before he installed it:

Next step was to make it a little nicer with another skull:

The black foam was just because he was waiting for some 0.3mm CF sheet but as soon as he got it he replaced the black foam:

Hi man yall quality is off the hook. Question how do yall cut carbon fiber I have cloth which I made mounts with but man when I cut shapes out with dremel cutter it leaves hair of carbon cloth on edges that even if I sand wont go away even cloth is unbelievably hard to cut guess I bought to thick a cloth . Man I wish I could get mine like yalls my hats off to yall

[nata2run]

Hallo Manuel & Christian, ok, so its not a coffe machine! could have fooled me :)....my question though, what is useed to bond the carbon on all christians brackets? and also what is the black/dark filling over the intake? is it just epoxy with color or something special? and....what was used to paint the bottom over the intakes?

[Chrisg81983]

Amazing work

[ManuelW]

@ Kent:

He uses either regular 2K epoxy or UHU Endfest 300 (its a special brand like Loctite and basically also a 2K epoxy system but it can be tempered) which is thickened with the right amount cotton flock and thixotropic agent. Then its colored black with suitable black epoxy color, you just have to add 2-3% to the resin to get the desired color.

For the painting of the bottom: As far as I know simply a high quality 1K spray can?

regards,
Manuel

[nata2run]

Thanks for the info, so no teardrop on the buttom hull for the intake?

[drwayne]

Thanks for the info, so no teardrop on the buttom hull for the intake?

+1 ??

[Cervelo]

Hi Guys,

@ Kent: Well I made a teardrop intake, but I did the modification after taking the picture. As it was on the photo it just wouldn't work very good.

But what I also want to show you is the latest update from my rudder. As you may have already seen I did disassemble it and polished all parts to a mirror like finish. But I thought for another update so I disassembled it another time and had a few parts laser engraved. This was done by a colleague from the german discussion board. And I have to admit he did an excellent job, its the same one who did already a similar work on my drives.

Here a few pictures of the result:

And yet another Wow! The rudder was already a work of art. For that matter so is everthing else!

[Chrisg81983]

this thing just keeps getting better and better...... Great work

[metalsak]

cristian and manuel hi....how you see the boat with the square end of drives on back of drive dog?? i ask because i usualy milled in a conical way my drives on the back(especially the small ones)....as i see you make the final points of the piece of art....thank you so much that i see this building!!! greetings stelios.

[ManuelW]

Hi Stelios,

well not to make it conical was done on purpose. Its my design with some info about CFD (Computational Fluid Dynamics), for normal purpose I don't think you will notice a difference but in such applications it could.

regards,
Manuel

[metalsak]
