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

[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 ..............

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

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:

Here a few pictures how the boat looks with the new rc box and the turbines inside:

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...

So now the review is up-to-date and on the same level as in the german powerboat forum. I'll continue the work when Christian has finished the new powertrimms for the boat - completely new and designed using CAD-software.

Best regards and have a nice evening,
Manuel

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.






(on the left you can see the turning machine)

Best regards,
Manuel

Well, you dont get to be called Sir File-Alot for nothing 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

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

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

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!!
