Darin's Top Speed 2 FE Conversion...

Well, I have a really basic question since I can't seem to find it searching on my own...

Where did you guys get your outboards? The only thing I can find is the Aquacraft EP-1 and Graupner--is this what you are using with different motors? TIA...Pete M

Darin, in this picture, can you tell me what sizes of tubing did you use? Thanks

I don't really remember... I think the water lines are 5/32"... The three for the ESC wires are "big enough to fit the contacts w/ shrink through", and kind of the same deal on the steering... They were all just bits and pieces from my brass tubing box...

ok thanks!! Im trying to win one on ebay, and if so Ill be following pretty much the setup

Did you get it? They are alot of fun to run,and fun to build.!!http://www.youtube.com/watch?v=sUteIPgYuAE Crappy video of mine.

I finally finished the orange TS2 I bought off the swap shop forum a couple of months back. (It was a bit of a challenge considering the state I received it in, but that's a different story for a different thread).

First off, here's the setup:

SV27 motor on a REK lower tilted up a bit to (try) and lift the nose, 70A ETTI ESC, Octura X440 2 blade and...12 IB 3600's

What a dismal failure.

It's WAY too heavy with nimh cells. The prop cavitated like crazy. The nose actually plowed down into the water at least once, and the water pickup was basically non functional because of the cavitation. I tried to lower the outboard a bit, then tried a graupner 40mm CF prop, neither made much difference.

So basically, it was slow (like 10-12mph), WAY too hot and tried to end it all by heading for Davy Jone's locker a couple of times. Let's just say, I ended that trip to the pond shortly after it started.

Ok, I know now that this setup is not even worth considering nimh's, Lipo's are a must.

My question is about prop selection, outboard depth and angle, what prop would be better? I think my overly aggressive upward angle contributed to the cavitation too, do you agree?

[TRUNKMUNKY]

Maybe I can help.,you must have the lower unit set at the proper height,this will mean using the ts2 manual.Just use the biggest side of the stand it came with to set your boat on,then you can set the motor and lower unit height,..just make sure you use the wide side of the boat stand.

[Stinger9D9]

Yeah, I think the motor was too low in the water, the prop was in too deep, and could not wind out. It started to get going, but looked like the motor just could not get the rpm needed to push the boat up on plane properly.

Has anyone had any success at all running one of these on nimh's? Or will I have to put it back on the shelf until the budget allows for a pair of those?

[smm_cbf]

im sure it can get on to plan with cells. you might just have to find the right balance point, i might do a bby tunnel on 12 cells, but thats built for cells, so....

[Stinger9D9]

Ok, I raised the motor up to get the bottom of the prop shaft 1/8" above the bottom of the sponsons, and also trimmed it to exactly neutral.

It's better, notceably faster (still pretty slow though), but it still runs REALLY wet. I still don't think the motor is hitting full rpm.

I think I read somewhere that the SV motor likes to be a bit higher out of the water than the recommended 1/8" above the sponsons. I'll need to slot out the dubro mount a bit to get the lower unit higher up.

The motor ran really hot again. I think a better water jacket is in order as well.

anybody know where to get the mount? looks perfect for my next build
