Pro Boat Formula Fastech Jet Drive Project

[Jesse J]

I remember that one!! Good stories never die!

Holy crap talk about digging up an old thread......LOL

[sundog]

I was doing some research for a project which led me to this thread. It is where Dan (Diegoboy) fit a Graupner jet drive into a Formula Fastech seven or so years ago. In it - with my infinite wisdom I told him that it wasn't going to work. That the intake was too far forward (would suck air at high speeds) and there was a more suitable drive available. He didn't take that well, but was gracious and went on with the build which ended up just fine. In fact, with the motor and intake both being forward like that, it eliminated the hopping that is associated with overdriven jet drives.

Anyways, I must have gotten sidetracked as I don't see where I apologized for being absolutely wrong, I seem to have just left the scene. So for the record Danny, I was wrong (as you well know) and I want to thank you for being a gentleman about it all and for adding to my (not so infinite) knowledge of jet drives.

Thanks! Sounds like something i can handle, I just need to figure out how to get the deck rails off without breaking the hull.. any tips? I have already ordered new rails incase i have to break them off.

[egneg]

I sanded the hull with 600 grit wet/dry. I then used Duplicolor Pro Shop lacquer red and then clear shot through a 1.0 detail gun. Buffed the clear with Turtle wax liquid polishing compound using a 6" buffer and a wool pad. Make sure the humidity is low or the clear will blush - learned this the hard way.

Awesome Project! LOVE the paint! what kind of paint/prep did you use? I am think ing of painting my stock fastech and I am not sure what kind of paint I can use on it.

Nice work!

I gave up on planes long ago. I still like them, so I'm trying to put floats on a plane that will not fly, boat functions only with a spinning plane prop for looks only.

[vvviivvv]

Nice boat! What is the length? Who makes it? Is it a Graupner boat? Is it fiberglass or ABS plastic? Sorry to ask so many questions but I'm thinking about building a scale boat and I really like the one you have pictured!

its fiberglass, it is graupner's kit... this is what you start with.

those aren't my pics thats just a idea of what you have to do... looks easy but drilling 1,5mm brass tube with a 1mm drill is a 'tad' frustrating

[vvviivvv]

To be honest, this is the speeds i am aiming for...

Hey Diego;
I learned how to crash Planes this summer. Great fun. and faster than boats.
I didn't stray too far, they are all Seaplanes. I live on a lake remember.
I just signed a Dealership agreement with Pulso, they make brushless motors for planes and ESCs to run them, along with Helicopters, Cars and Boats. Boat ESCs from 40A up to 200A. They look good, I haven't recieved my first order of stock yet, I tested a motor before I signed. Nice motor. I should get a shipment next week.
Have you run the rapids with that pretty boat yet ??
Later;
that Viking

it's had graupner 700 bb turbo's for about a year on 9,6v sticks each... nice scale speed nothing impressive, the inside is abit of a mess because i needed to modify bits after installing the deck which is HARD this is about the only pic i have of before i stripped the 700's, the feiago install isnt complete...


wow wrong pic

[Darin Jordan]

Ive got the boat these jets where intended for (2)... i was planning 2 feiago 8xl's on 4s, would be straight line speed only as its a fast scale boat, would these be overkill? it is a big ish boat... on 4s

im sure there the same jet units just i have the reverse mechanism attached...
geared 1:2 i think (forgot to mention)

I'm always VERY impressed with these major scale builds... VERY nice. Would love to see more pics.

Would love to see under the bonnet on your rig , nice boat

[Darin Jordan]

Thank you!
No spin-outs, so no turn-fins needed! She runs very well too. I'm pleased

I just need to be sure the TX batteries are the proper voltage to give me some range.

Diego,

Do you have any video footage of this boat running? Would love to see it! I found this on YouTube: http://www.youtube.com/watch?v=BQ6ABJfr7Fk
