MHZ Mystic 1380mm build

[nata2run]

Hello Everyone,
I thought I would start this thread as I have the Carbon/Kevlar 1380mm 54" MHZ Mystic on order including hardware. Should be here next week or so. :banana:

The plan is to keep this one on a semi budget but make use of my Lehners (2250/5 D on 5s) or (2250/8.5 Wye on 8s) May be a bit on the short side but I'm not looking for TOP speed at the moment 130-150km/h. I would rather spend the time to get a nice build and paint job, and ofcause have some fun on the big lake.

I havent desided on a theme yet, but I quite like the Lehner colours for the inside of the hull (black purple & chrome) so lots of carbon, anodized aluminium & polished steel.

If anyone have any ideas, please share so we can all learn something.

Do you have the drives yet? The new click drives are really nice! Similar to Christians drives on his turbine HPR.

Wow, those are really nice. But I already ordered the MHZ, same with the rudder, I got the scale rudder from MHZ as well

I guess those will work! :)

[nata2run]

Hmmm you should have known what was on my mind and told me yesterday lol
Man, I really like those. I couldn't figure out, do they have ball bearings installed?

[nata2run]

Just ordered, SAVOX SC-1251MG Low Profile Digital Servo. Should be ok

[bruiser77]

MHZ external antennas are nice, clean and removeable!

These are not just ok.. they are great i have 3 of these used for my boats . Good call on the servo i would say!

[bruiser77]

I'm using the small version that I got from a forum member should work great.

[Espresso]

What exactly does this mini antenna do? I've seen these on some boats while I've also seen a really short antenna tube. For the spectrum MR200/MR3000, the exposed antenna wire is only like 3" long if that.

[bruiser77]

It does the same thing, just a clean and removable external antenna mount that will extend the range. A must for carbon hulls.

[srislash]

So how does it work with a co axial cable/antenna wire?

[bruiser77]

It's got a washer with a eye to attach the rx antenna to the external antenna lower shaft that attaches to the hull.

[Espresso]

So your Rx wire itself remains in the hull or is it threaded through the loops on this MHZ antenna?

[bruiser77]

The rx wire stays in the hull and the external antenna with the loops is what is removable after running/storage.

[numse1964]

Hi

Do you use this kind of antenna with a 2,4 ghz radio ?
- I thought that was a bad idear.

I use this with my 40 mhz radio. And it's realy good and comfy.

Best regards Henrik

[bruiser77]

I hope it works with 2.4, thats what im going to use it with. we shall see.

[nata2run]

I love the idea of a removable antenna, can someone confirm it works with 2.4ghz?..... Maybe I can get an extra long antenna and win the "INCH" game over bruiser LOL 2" short damn LOL

[srislash]

What are you guys comparing now...:roflol:

[nata2run]

What are you guys comparing now...:roflol:
Hey Shawn, stick to the subject LOL - the thread here is My new "big" boat! LOL, dont destract bruiser, he's got work to do!

[nata2run]

Ok, back to the real world again. Just looking at propshop's site. where would you guys start?
I'm going to give up on the traditional x447 for a hull this size.

5017/2 - 5517/2 or in the 60's ?

I think I'm hooked on the 8s setup motor is around 1380kv in wye mode

[bruiser77]

With that size boat you probably wanna run a 442 at max!!!!! LOL! I'm so distRacted now! LOL!

[srislash]

I would think something in the 55 range should be appropriate.Should have some choices there.Fightercat has 5518's
Mind you with 1380kv on 8s that is some RPM.50's or 52's then.

[srislash]

Hmmm you should have known what was on my mind and told me yesterday lol
Man, I really like those. I couldn't figure out, do they have ball bearings installed? So do these have bearings?I'm still aquiring information for my winters build.It may have gotton bigger now:hornets_nest:.

[nata2run]

So do these have bearings?I'm still aquiring information for my winters build.It may have gotton bigger now:hornets_nest:.

I would ever only build what I can fit on the back seat LOL. RPM wise I'll be in the 37k on 8s so it should pull a 50' something prop. 140km/h would be nice.

[nata2run]

I think the Doc has some 5518/3 from propshop, wonder if I can pull them safely. Potential to hit 100mph with something like that! That's if the lehners can handle it. Few more days and hull should be here.

[Chrisg81983]

Can't wait to see this
I bought the Hpr drives by the way they should shpi out monday thanks for the help
Chris g

[nata2run]

Congrats on getting the HPR, I was a 1/1000's of an inch from getting the 135 HPR!!! MHZ gave me a deal I couldnt refuse so I ended up with that. Hanspeter has some amazing Hulls though. and I always enjoy watching them getting build :) Kinda glad I got the MHZ though, just look at Christians new turbine powered monster! "so I keep telling myself anyway"

Would be good to follow your build threat, all the best of luck. (although luck is for the unprepared)

[nata2run]

Hull should arrive tomorrow or the day after, really looking forward to this one. Hopefully everything is in one piece.

HOHOHO, HULL is here .... In my car :spy:

[Chrisg81983]

Pics please

[srislash]

C'mon open it!!!

[nata2run]

OK, She's here!!!
Thought I'd share the first photos. Looks smaller in the picture but shes quite big compared. (maybe because the 114 sits higher on the stand) This should be alot of fun.
Also ordered some carbon 3.5mm sheets, that I will be using + servo arms that I will be polishing chrome. I think I will go back to the traditional motor mounts as I want to use the 8mm thrust bearings. How ever, there will be 2 mounts per side on the front. Sorta like the honey combe design but without the combe. first mount will have the 14mm center hole for the motor bearing half way through, the second just the 8mm for the shaft. then a 0.5mm aluminium plate, for the thrust bearing. Both mounts will screw togeter with a 4mm spacer. So it will look like the honey combe but instead 7mm of carbon. It will then have the lehner bracket for the back support.

[Remmie81]

Looking nice!!!

I will follow this build!

[nata2run]

Thank you Remmie, will follow yours too :wink:

[nata2run]

Ok Guys,
to better understand what I'm planning to do with the mounts here is a little drawing. So 2 mounts for the front bonded with spacers. 1 mount for the back from Lehner. (will make a back bracket so it can screw on and come off anytime.

[Remmie81]

Nata,

I like the design of your motor mounts, but (forgive me) I do not understand the idea behind it.
Why double on the front?

[srislash]

Kent,how big are the Lehners compared to the 1717's? Just curious. Looks like a good mount setup.

[nata2run]

Nata,

I like the design of your motor mounts, but (forgive me) I do not understand the idea behind it.
Why double on the front?

Remmie,
The idea serves a couple of things. I have learned my lessons from the past. Let me explain. Soon as you leave room for the wind up (3mm) the stingers just sit there and hold the shaft in place. All the preasure/load is on the bearings of the motors and the mount itself holding the motors, making it very easy to break if you have a crash or hit something in the water. The purpose of this setup is, the 2 mounts help each other and become double the strengh or more. instead of all the power be located on one 3.5mm mount its now in an area of 10mm (2x3.5mm plus gap) it also allows me to run extended bolts through the mounts and cover with epoxy (total area covered with epoxy will be close to 20mm) The mount will never give!!! Also, I'm saving the motors by having a thrust bearing on the second/front mount. that means the collet will push on the bearing of the mount and not the bearing of the motors.

[nata2run]

Kent,how big are the Lehners compared to the 1717's? Just curious. Looks like a good mount setup.

I think the Lehners are on path with the 1717 but in a smaller package. If I understand right the Lehners will handle alot more RPM. They seem to be build like a brick and no wobly parts and loose bearings like the 1717's have. But power wise, I think its close. I will benefit from the RPM and the fact I can run both 5s-(6s HOT) and 8s just by swopping leads.
The lehners are slightly thinner but a bit longer 1/2" or so

[Prop-a-Gator]

Unique motor mount design. Sounds like you are going for bullet proof-ness. Any chance you'll put some fillets in those inside corners? Sharp inside corners are stress risers, but it seems no one bothers rounding them on these motor mounts - not that I've ever heard of one breaking.

The hull makes those Lehners look tiny. I would've needed a roof rack or a trailer to get it home! :lol: This will be an awesome build.:popcorn2:

HEHE,
Not going bullet prof, but want to make sure motors stay in place and not move. You just never know what might happen. Its not going to harm making it stronger. Your quite right, the Lehners look so small. Its amazing they have enough power to push the hull 90+mph (not saying thats what I will do) but the power is there on the right setup. I will definetly do my best to make everything line up and make everything run as smooth as I can. Measure twice, make a template then test and install.

[Remmie81]

Thanks for the explanation.
I think its a perfect solution!!!

Grtz Remmie

[nata2run]

Thank you Remmie, I hope it will work in my favor. The whole idea is to make an even better build than the 114. The last thing I want is parts flying off or misfailure because of me. I run in a small lake with people around. It's better to take precaution and make it right.

[nata2run]

Ok,
Been spending some time on the drawing board. Here are the Carbon parts.
77110

[jkr]

Nice job.

[srislash]

That'll look cool in there bud.

[nata2run]

The plan is to have the components under the carbon and purple anodized under the cutouts. Just printing templates at the moments to see if it fits nicely. Unfortunately I'll be using a lot of carbon. Few hundred bucks. Grrreee. But don't want to compromise. Have to finish of the battery treys. Also working on the template/jig to cut the holes for the drives. Carbon should arrive before the weekend.

[drwayne]

OSE CF bat trays are cheap at 12US ea.. I understand the uber need to do everything yourself, what I dont understand is the need to waste so much time copying something readily available from a friend ?
Cripes, Bruiser will be on the water before you !

ps. love ya work !

And damn straight I'm ready for the pond.

[nata2run]

Thanks Remmie, I can't wait to see the result my self. Will have to wait till tomorrow, they are still covered in protective tape and stuck to the sacrificial sheet. Have to clean up and run some superglue around the edges to seal. Should have them ready by tomorrow.

Carbon bits look great! Can't wait to see this build really get going. I think the purple should be translucent and back-lit!! :banana:
Also looking forward to seeing DrW's uber Genesis hit the water. Does anyone sell the painted 56" Genesis hull in the States?

[nata2run]

Thanks gator, don't think that hasn't been on my mind lol. I even have the panels for the backlid. Got blue and white but could ad the purple film. Could even insert acrylic into the cuts so it would be flush. Hmm but the window on the cowl should be clear..."...nah come on LOL

Been working on the motor mounts to see if the motors fit, plenty of room there. This is the result so far. Also made little flex shaft holders that elevate up/down and left/right. Again the bottom screws are to alow for better bond to the hull "concept im working on for this build" so it will have that consistent look.

Pity is the TFL aint mine !
On it's maiden run, spun the collet RHS at 1.36 .tightened both till thought the nuts would slip ! .. . and at end the LHS prop and shaft stub , lost to the pond monster ...fractured outside of stinger...dog and all ! 8(
The 1/4 to 3/16 shaft is great for prop selection, but not ok for the power squeezed through it.
Oh well.. all 1/4 now.. owner ordered new props from propshop-UK.. now waiting for sunshine and wamrth !

Kent's looked impressive today.
Lots of up and go !
remind him to return those props !
haha

[Prop-a-Gator]

Looking good Kent. No wah-wah. What did you adjust or was it just the props? If so, you may want to tell Doc you lost them in the pond too. :wink:

[nata2run]

Nah not props, moved stingers up to neutral position and moved batteries forward. Just never thought I had to move them that much forward. But can experiment with smaller props now and more cell count. Ppl that get those boats running on 6s got 2200kv motors, that's a lot more rpm then what I run on my 1580kv.

Kent did you ever try the 1717's on a higher cell count

No not doing that, the bearing is on the outside of the mount. Reason for 2sheets of carbon is extra strength. Don't want things to flex. There is a lot of power going through the hull. The lelief is for the bearing on the lehner, it's not flush to the front plate but poking out about 0.5mm. Will take some more photos as build comes along.

[nata2run]

Kent did you ever try the 1717's on a higher cell count

Nope, not done that but have 8s waiting to test on smaller props. Should be good fun, there was no point trying to put more power through if it wasn't smooth on the water.

you need compressed air to blow out every bit of carbon dust from inside else the motors will ingest it, and get belly ache.

All cool, will do and do regularly as well. What I ment to say with the carbon was... that I mixed some carbon dust with the epoxy (looks cool) and may be stronger dunno. Once im done drilling I will clean the hull inside in methonol. (and then blow compressed air again)

[nata2run]

The Doc. came to the rescue again today. He happend to have some CF cloth I could use. (Very minor amount used)
Wanted to get something strong for the tubes,s so got them wrapped in CF. Ideal would have been heat shrink and then get that to clamp around, but didnt have any big enough so used some cling film to wrap around as epoxy is setting off.

Many hours sanding and then polish should look nice. Here they are before applying the epoxy.

Hello guys,
Got a few things done. drilled holes for the rudder, installed water pickups (still need to cut the teardrop) glued/waterproofed the drivers.
little luck will be on the lake in no time.

Lookin good

[drwayne]

Apologies upfront . you do know lots.. however, the pix suggest the water pickup tube leans fwd, making in a drain ?
More pics could offer clarity..
Luv ya work.

Maybe drain is a good idea when I fill up with water :). I have now dremmeled the teardrop shape into the hull. Illustration shows the configuration of the jets & cut.
regarding leaning forward....well regardless, thats the way the hoses will go anyway. Will see in the pond how good it works, but I'm glad I got them that close to the tunnel.

[Chrisg81983]

Once that teardrop is filed out they look like they will be perfect looks great keep up the nice work

[nata2run]

Thanks Chris, I hope it works as planned.
This is how I did it.

77749

[Chrisg81983]

I have used the same method many times and it works flawlessly so it looks like you will be ok

[drwayne]

ahahhh

without the tear drops it wouldve been all over !

[Chrisg81983]

No without the tear drops there will be tear drops (crying)

[nata2run]

Well lets just hope those "working" "tear drops" are not from my face :)

[Chrisg81983]

I hear that I am sure it will be fine My Hpr is stuck in Germany for some reason it has not moved since the 26th I am hoping all is ok else I will have those teardrops we are talking about it's been 10 days total and it moved once

[nata2run]

It could be at you local facility, just not updated/logged yet. you may see it in the next few days or so??

[Chrisg81983]

I really hope so

[Eric Ho]

If its DHL you got to bug them more.....I had them arrive late and unrecorded.

[Chrisg81983]

I called Dhl and they said i need to call their express line so I called them and they said it is going to go to my local post office but still no word thanks everyone for all your help

[nata2run]

Hello Guys, got abit done. Installed rudder and the pull/pull wires...what a P.O.S. idea MHZ Pull/pulls!! definetly have to rework that and use thinner wire. With the holes and stuff to get it working smooth boat will sink before it gets moving. If it wasen't for the perfect alignment of the motors and flex drives, I would of had a bad night!! Stuffing tube support now got carbon rod rather than screws on the bottom part. I think its coming along ok.

Carbonicious! Carboniferous!

[srislash]

Coming along nicely Kent.What are you gonna run for props?

[nata2run]

Thanks guys,
Well I'm going to do what we should all be doing... start off small and work our way up. x447 will be first on 8s, then 450/3 maybe? would like to run something like 5517/2 or 57something high pitch. but I dunno. 90mph would be the max I think i could get, but I am a long way from that.

[Chrisg81983]

Looks totally awesome and i love the carbon plate work. I would like to speak to you about making me some parts if you are interested ?

[Prop-a-Gator]

I really like your flex shaft holder design. Looks great mounted to the carbon-sheathed flex tubes. I've never built a twin. Is it ok to have that much flex showing between the tube and the coupler? Is that gap to allow removal of the coupler nut?

[nata2run]

Thanks Gator,
by the time I get the nut back on and install a flex saver there will be less than half an inch showing. I think it should be ok, less chance of snapping if slightly misaligned. Can wobble but half an inch should be ok.

[nata2run]

Ok, Got some more done, and worked on the pull/pull system. Still not 100% happy but never mind. Just need to waterproof a few spots loctite all screws, add ESC's. Drive to pond :)
Oh and props are 4818/3 on 8s

You're making it look too easy. Always a fast builder. Almost time to start looking for your next hull. ;)
BTW... have you seen the 1.8 pitch CNC props on FCR (http://fightercatracing.com/index.php?page=shop.product_details&flypage=flypage.tpl&product_id=244&category_id=26&option=com_virtuemart&Itemid=1)? 50-55mm DIA. Too big for me, but sounds like you were looking for something in that range.

Hehe, I hope I can make it look easy, that's the point no? How ever you can do it fast when you have all the machines to cut things out. Some may argue that it's cheating because the machine did it. But does it apply if you build the machine too? Resin only takes 24 hours to cure. By the way props are similar to FC's they are 4818 CNC. I noticed they don't bend they snap. Looks to be very good quality

Has anyone out there completed the rudder pull/pull on one of those. I seriously dont like the way its sugested by MHZ. I much rather the wires runing inside tubes way above the waterline. But I dont want to reinvent the plate :) the way it is now, hull will definely take in water!

LOL ok then...... I got the props locally. They look to be of good quality. I had a x445 from the same company, and they are tough as! Accidently hit something and it just snapped no bend or anything just snapped. So they are hard as. They are so light you can't even balance lol... Hopefully I can finish off the build soon and get her on the water. Just curious to see how she performs before I invest in a nice paint job. Forecast looks good though, and I'm confident I didn't spare anything or cut corners.

[drwayne]

yes pull pull
rods at very end for emulaton of hydraulic ram.

[Prop-a-Gator]

I don't think you need to worry about anyone accusing you of "cheating" for using CNC to cut your parts. I wish I had access to CNC & laser/water cutter. Nor would I think cutting corners is in your vocabulary based on your builds. Your quick and clean builds are a testament to your planning and preparation. Nice work, nata. :beerchug:
Checking the forecast... you must be close to finished ;)

[nata2run]

Ok, so how are they entering the hull? Any tubes for the wires? Have you got close up pics?

Hehe, thanks Gator for the confidence. I hear too often, "oh you just have to push a button" well yeah! If I can get it done in a tenth of the time then why not. And its accurate and consistent. About being close to finish.....well look wise it's coming to an end, but there is still plenty to be done, not to mention all the setup. The setup as is now is capable of 90mph and beyond. To actually get it there is a different story. ...... And that's the part I lack.

[nata2run]

True true, as long as you learn a little every time you go out its all good. I still have a bad fear of crashing or boat going boom. With the speed we are doing comes much more risk, no room for a lot of error. But never mind. Tonight I got the anodized purple aluminum under the carbon, looks good! Will take some pics tomorrow.. When my carbon plate lands it's of to make the treys for the lipos. And I guess after that it's just small cosmetic details before I declare done.

umm yep :)
you can check it out on their website under counter rotating props. you'll see the the 48, 50 they are all 1.8 even though it dont state. Says on the prop though :)

[Chrisg81983]

Kent what type of epoxy resin do u use

[nata2run]

I spot glued with 6min epoxy mixed with carbon filings/dust, then I used a 2 part resin from West Systems 105 part A + hardner, its a 24hour i believe. It took a while to cure (they sent me a sample pack for free) just enough to glue in the mounts. I think you can use any 24 hour epoxy resin for carbon fiber. as long as the hull and mounts are carbon. not seure what to do if hull is glass??

[Chrisg81983]

I was thinking of using the west systems epoxy but I was unsure if it would bond to the carbon / Kevlar plus my Hpr has an extra layer of glass over the carbon/Kevlar I am in the middle of talking to Manuel about him sending me some of the epoxy he uses in his builds as he needs to send me the rest of my parts.

[nata2run]

Maybe talk to Manuel, as he would know for sure. No.1 importent though, is to make sure you prep right for the job. Cleaning the area using thinners or acetone sanding with 80grid sanding paper even heating up the area with a hair dryer/heat gun. Lots of different ways. As long as it holds :) thats the main thing

[nata2run]

Thought I'd upload some more photos, got the purple anodized aluminium under the carbon.

[srislash]

Looks good Kent:drool:, I like the inlay look,Awesome.Did you find the coloured tubing at Bitz as well or did you do that?I have been doing my own but I saw someone with white on the board.I never got a reply as to where they got it.Those props do say 1.8 don't they.mmm 6s

[Remmie81]

Its not about Epoxy bonding to carbon or glass, it will do both as long as you roughen up the surface and make sure its clean (grease and dust free)
its about epoxy bonding to another resin.

Epoxy -> Polyester = YES
Polyester -> Epoxy = NO

I keep following your built Kent! Its awesome!!

I certainly like the theme! ;):thumbup:
I thought about adding the orange and red stripes from the black & silver AquaMania boat to mine just to give it more color on the water. Wasn't sure how it would look and didn't put any effort into laying it out on the pc.

Gator if that's yours in the pic, that looks awesome. Where you get the graphic from?

[Prop-a-Gator]

Thanks! Someone posted the black/silver decal set on one of the forums. I modified it on PSElements into the white version. (red surround, metallic gradient in the lettering, etc) Some of the graphics from that set were hi res - others low res. It took some doctoring on some (flags) to even look decent. There are better pics in my album. I printed on water slide decal paper with an inkjet. Would have been better with a laser jet, but you can only tell up close. I know they'll fade over time, but they'll probably last longer than my boat with my driving skills. lol

LOL @ Chris, lots of machines I wish I had. Never thought the machines I have were going to be used for boats.

@ PF3X, thanks for the compliments.

Anyway, didnt have alot of time today to work on the boat, but got some electrical done plus the "Star" for the motor (Enables the motor in WYE mode and can be use for 8s around 1370kv, compared to Delta 2365kv i think) I also got the leads wrapped with mesh to hide the black, red, and white. And for minor protection. Next will be some more water proofing and mounting the ESC's 5-8 more hours and she's good for her maiden.

7858678587

[nata2run]

Hi everyone, trying to work out the ESC's hmmm they fit fine but by doing this will have to extend the battery leads.
Worse case they have to be top mounted. They also fit in the sponsons behind the motors :) ...ahh well still thinking

78713

[Remmie81]

Cant you put the ESC's sideways?
Then connect the lipo thats in the left sponson with the right engine and vice versa.
Then you can have the minimum wire lenght possible I think.

But I dont know if that will fitt under your awesome carbon work.

Grtz,
Remmie

[nata2run]

Remmie, I wish, but the holding screws are in the way. If I was able to fit them that way "if I modify" I don't think it would look very good as you would see the ends? I wonder how bad it would be to extend the wires 10cm 8guage? How much power would get lost? And how hot? I have tried behind the motors, it don't look bad.

[drwayne]

put them on the wall behind the escs.
see brusier77 daytona thread where he placed the FC esc for example.

[nata2run]

put them on the outside wall behind the escs.

That's what I ment about the behind motors "parallel to the motors" if you look closely at the picture there is a black strip of Velcro next to the motor. It don't look too bad.

[Remmie81]

Ok if sideways is not possible then I would mount them on the walls between the motors and batteries if possible.
Then your tunnel stays very clean, you can design something new to make mounts and covers for them on the sides.
everything is lined-up then and you can go with short wires.

This was my idea for my MHZ 114 as well.

TFL56 for SF300A

[Remmie81]

LOL, at least we are all talking about the same solution :thumbup:

[nata2run]

Wow, they are big and heavy esc's. I have to think a little more as I want it to look as nice as possible.

[Remmie81]

Just an idea but if you would put velcro on the walls and on the ESC's, then you can always remove them in case you need to.
Then if you make these stands (like the ones you have on your tunnel were the bolts of your carbon plate go into) and mount
them on the walls you can put a carbon plate in front of the ESC's so they are almost not visible.

So the same idea as you have now on the tunnel but then on the walls of the sponsons

[drwayne]

[nata2run]

@ Wayne, woohoo good to hear, sadly when they get here you may loose them to me :) .!!
@ Everyone, the plan was to have them under the carbon....."I WILL MAKE THEM FIT" who says you can't trim a little here and there LOL.

Thats not a bad idea, will do as my last way out if I cant fit them any other way, I would then cut the same pattern in them as on the plates but have them light up when the ESC's are armed :)

[Remmie81]

[nata2run]

Ok Fellas, Almost done. I decided to go with my orriginal plan and mount the ESC's under the carbon. To make it work without extending the wires I just had to spin the ESC' around and move them up towards the front, I didnt want to do that before but it should be ok. Still plenty room for playing with COG. I had to make the stand off's longer too. for that I just used some aluminiun tube that slides over the exsisting mounts, coated with the Dupli Metal Cast purple. Just some final touches and a bit more water proofing "just to be sure" and we're off for maiden.

I'm aware that delicate electronics "ESC's" need better control/cooling than plain copper wires inside a motor, it's logic for cage chickens. In my curent setup to keep the temps down/cold, this worked better. (For me) Im by no means arguing whats best for this setup. Of cause when you push the electronic side of things, it will need the most cooling, plus I believe the motors can handle alot more heat than the ESC's.

[nata2run]

Good morning everyone , this is your captain speaking :lol:
Ok I have re wired all the cooling to feed the ESC's first "that will keep the Doc happy" specially if it blows, then he can fix without feeling bad, that it was wrongly wired. So shes done as far as I can tell, and hoping for a maiden this weekend yeahhh..

[Chrisg81983]

Looks very good and good luck with the maiden run take a video please. What is the positioning of your lipos and are you running 1 or 2 packs to each motor

Thank you chris, lipos will be in the sponsons as usual, COG start around 35% and work my way up. 6s1p 5000 per side to start off with, then 8s1p 5000 per side if all good.

[Chrisg81983]

Are you putting any type of lipo trays in along with straps to hold them in place. Kent I have been told as well from many creditable people that esc's will take more heat than the motor. At the heat range a motor starts to demagnetize itself a esc can run fine at. It kinda makes sence but I need to look into it further.

Chris, I'm no expert here. But I didn't think the electronics could handle running very hot, I have seen caps and other components blow at 80-85c (I consider that hot) I guess I have heard so many things I dont know what to believe? sometime what should makes sence, make no sence at all. All I can say is, that I dont push any components to the stage of getting burning hot. Never blown anything inside a boat (outside yes LOL) I wouldnt push my components to the limit for an extra 5-8mph as I dont race, this is for pure fun on the lake. So again if the motors starts to heat up, and ESC's are cool, I'll swop the cooling again :) easy done.

Regarding lipos, Im making a slide system when my carbon gets here. till then, just using pool noodle and Velcro to hold in place as I test.

Oh on a side note, SF240HV $250
Lehner 2250 $600
Hmm, wonder what I would look after the most

Got the cooling sorted today, just the last little bits for the exit of the hull. also installed the support rod between the two motormounts. seems like I'm getting less vibrations, and its now hard to squash the two sides in. She should be ready for a maiden, but I find it a bit unsecure to install the batteries with no mounts. May have to consider. I really want her on the water though!!!

[jcald2000]

Carbon Fiber conducts elec, the thin coat of epoxy over the C/F is NOT much insullation. I have seen an $800.00 schultz mounted on a C/F plate burn from a dead short across the + and - on 10s almost took out the tent canopy!!!!
C/F looks great but can be deadly used wrong!!!

[nata2run]

Unless the servo is in danger from being mounted directlty to the plate, I can't see what can go wrong? There is 3mm rubber between the esc's and the mounts plus the insulation around the esc's. I'm assuming everyone that uses carbon know not to mount any electrical components directly. I guess someone with a $800 schulze controller mounted directly onto carbon has no business in the boat business.

Quite nice for a maiden I would say, nice in the water and a good speed of 102.4km/h on only 6s with the 4818/3.

Oh had some. Cooling problems. Could be the pickups or could be the 3mm tube that I used. Will install 4mm tube and see how we go. No chance of running the way it is.

[nata2run]

Does any of you guys have a photo of your under hull "home filed" pickups just want to make sure mine are right. Didn't seem to cool very well. Don't want to have to install a metal one at this point.

[srislash]

So how bad was it?Have you tested the rest of the cooling system?And are your cooling tubes going up at a 90 degree angle in relation to the ride pad?

[nata2run]

So how bad was it?Have you tested the rest of the cooling system?And are your cooling tubes going up at a 90 degree angle in relation to the ride pad?
Well it was bad enough, definitely can drive like this, you can blow through the cooling system but not with ease, if that makes sense. The pipe is at 90 degrees yes. But I wonder if the tear drop need to be a certain length or depth? The other option is to install a hose with a larger diameter.

What diameter is the hose now? I have gone thru all my fittings with a drill bit and make larger fittings for the cooling jackets.If it is having a hard time pushing the water thru opening the flow will help.On my Geico I got a good 1/8th throughout.The FC I think is 7/64th with 1/8 lines.
Another thing I can suggest is try to reinstall the 90 degree tube with a swept rearward angle to it.With them straight up you would need pressure built up to make water travel up them(I would think).
You could also elongate the teardrop.They do look a bit short.

Shawn, I think it a combination of small hose and "short teardrop" I have made the teardrop longer, so before I change the tube I'll see if it has made any effect if I change it all and no good then I'll turn to the metal ones that I know work. Did you watch the vid by the way? The doc has some more coming once it uploads, but I think his still on a 28 modem LOL

Yeah I watched the vid.It looks good.So those were the 4818's?It looks good and stable.I got to watch Docs now and I'm getting mine from yesterday up from the Shocker.

Nice to see her hit the water! Looks like she rides nice and flat

Regarding the cooling issue, are your temps high or are you not seeing water exit flow? Here is a link to a HPR115 build (http://bbs.5imx.com/bbs/viewthread.php?tid=411096&page=1#pid5323950) that I used as a guide for making my through hull inlets. The photography is some of the best I've seen for a build thread. Then again, I've noticed that Manuel doesn't bother with angling his water inlet tubes. His are basically vertical with a teardrop added like yours. If you have an adequate teardrop, you're probably fine.

If you're having trouble blowing through your cooling circuit, maybe you should check out the motor water jacket issue found in the link above. The water fittings were threaded too deep and impinged on the motor can - restricting flow. I'm not sure this is even possible with your LMT jackets since they don't look threaded, but thought I would mention.

Thanks gator, I have read that thread a while ago. Motor jackets are fine, no problem there, but tube is only 3mm and teardrops are/were small. I have now sorted the teardrop so will see how it turns out. If all works and can keep her cold, I'll hook up the 8s for some real fun.

Oh didn't really see any water flow from the exits

Looks good in the water Kent. Hope my maiden goes that well! Great job. FYI, I hooked up my receiver to the MHZ antenna and it works flawless.

Wunderschönes Boot.Super edel gebaut.Einfach der Wahnsinn.:thumbup:
Wünsche dir viel Erfolg bei der Erstfahrt.

Looks good !!! For the cooling problem if i remember correctly I think the tubes need to be angled a bit more. They seemed a little straight when you first did them. I will try to get some pics loaded with the pickups that I had. The only problem is the two boats they were on I sold. I should have some pics though

[nata2run]

@ Charles, YOUR ALIVE!! And thanks for the compliments. Of cause you will have a good maiden as you have invested a lot of effort in this build. I wish you all the best, and please.....get that boat done before Xmas.

@ Christian.... What can I say, your builds have been the number 1 inspiration for my builds, and here you are complimenting on my boat. I guess only thing to say is ... Thank you ... DANKE

(Christian .... Was kann ich sagen, Ihr eingebauter waren die Nummer 1 Inspiration für meine Boote, und hier sind Sie auf meinem Boot Komplimenteren. Nur, was ich sagen kann ist ... Ein großes DANKE)

@ Chris hopefully it will work after making the teardrop a little bigger. If not then I'll replace it with a proper under hull pickup. Don't know what possessed me to do it this way when a had a great success in installing in the other hull.

I upload slow because I know you like waiting ...

The Mystic had water flow, evident on my vid , but the motors returned as egg cooker cans.
Hopefully higher voltage and lower amp draw will result less heating.
The pickup teardrops were small .. more suited a small boat.. this cat needs LOTS !

FYI, these sf240hv esc cool by both air convection and water passthrough.
Kent has his esc wrapped in 3mm insulation squished between cf tray and deck.. not good for cooling the unit.

"Kent has his esc wrapped in 3mm insulation squished between cf tray and deck.. not good for cooling the unit."
Not wrapped just edges so they dont slide, there is still air between all the parts for airflow. I even made room for a fan if needed

please ask if in doupt of how things were made.
