Yay the boat and drive is here, thanks to the help of odessit. So to give the run down.

KMB 28mm jet drive, 28" billings jet boat.

Drive train
Intending to use a feigao 12L brushless motor. Using somewhere between 6-12 cells.

Thats about it for now, but there may be some surprises in the works.

Some pics of the boat drive and next to the jet-villain.

Nice. the hull of both boats look the same just longer !!
pretty cool ! good job

Quicksilver1

My first obstacle is how to armor the hull, I'm going with aluminum again probably, but thinner. and hopefully much neater. I dont want to paint the hull, so I've got to plan this out. If you can think of any easy way to attach metal to ABS without the risk of either losing it or making an ugly hull. I'm wondering rivets?

CadillacDTS2001

screw aluminum. Go with a sheet of carbon fiber and kevlar

Quicksilver1

ohh, I like how you think, flexible, lighter and stronger. Attaching a composite to plastic much easier. Which is less expensive and easier to get, I'm thinking carbon fiber, very very good idea. bet no one has put it on the outside before.

CadillacDTS2001

it isn't less expensive its more then aluminum.

Sweeet dude, very nice. Can't wait to see the results

Quicksilver1

well, I found a place that sells carbon fiber sheets, I can get a 11"x16" piece of CF of 24$, in either the classic style or some new aluminum carbon hybrid material. I like that silver hybrid stuff. good old hexanium lol, thats what its called.

Slap it on and go!... sorry I build the ........ for a living.

Thats it I am Waiting for the Day when Quicksilver Says " Vids done..Got my Girlfriend/fiancee/wife to drive the Villian for a Comparo, New Boat is Quicker"

cool project...cant wait to see the results...dont forget vids vids vids vids vids!

,,oh yeah, VIDS!

on the villain hull is there any stuff inside it when you buy it? I mean like is it flat on the bottom and cleared out like a bby hull when you get it or does it have plastic stuff all over to hold moter mounts and all that stuff. thanks mike

CadillacDTS2001

what do you mean like a bby hull?
Of course it has stuff in it it is a RTR boat.

Quicksilver1

thanks for the support guys, should be fun and there will be vids.

to answer the villain hull question, I highly modified that hull, copy and paste the address in my signature, thats the build thread.

Quicksilver1

small problem read up some more on the carbon fiber, there's a world wide shortage. Not so sure this is the best time to be purchasing the stuff. I'm taking other suggestions for armor. unless someone knows where to get some decently thick and decently priced CF.

edit: scratch that, I'm going with carbon fiber tape, easy to get, real, and cheap, not to mention tower hobbies has it, yay

great project..
love those jetdrives.

I have a question about the jets you like so much. I have a 33in flat bottom river boat made of fiberglass it is real old! put it this way it was old what I found it in a yard sale15 years ago. long story short I have painted it n was going about finding a jet for it then I hear the it won't every really be fast cuz jet boat RCs aren't very fast now I don't know if I want to finish it since the performance may not be worth the cost

joccee

If you want it to go fast then go for surface drive. But the feeling of a jetboat is incredible and they can go pretty fast to. search for qicksilvers vids on youtube and see for your self.

here is mine

Its only 18" and is powered by a graupner 19mm jet and a feigao 380 9s on 6 cells
I think the speed is decent. Could have been faster but I'm happy with how it turned out.


If you want speed out of a jetdrive, brushless is a must i think. And keeping the weight down.
jet have a "speedlimit". when you have reached the rpm were the jet is the most efficient it will not go fatser if you add more cells.
So a bit bigger motor with more torque and a few less cells will probably give you more fun than a high kv motor.
(I think someone off you english speaking folks could explain it better than me, i'm just a poor stupid swede so I'm a bit handicaped with the language)

Quicksilver1

you did admirably . I would add, it's a weight to horsepower type of situation. You want the most power from the least amount of weight, with a jet. I think you should go weigh that old fiberglass boat, then wed have a better idea.

CadillacDTS2001

who cares. lets get like 40 cells and a Lehner 22/40/*6 and hook it up and see how it goes. I'm sure it will push to much water you will be flooding the land

saleens7

some of us arent rich man...

...if only, if only.....

Quicksilver1

okay thats it you need to build one You know you want to

CadillacDTS2001

Haha yeah!. i know.

ok, I got something done today. After purchasing some brass, I spent a great portion of the day, cutting, bending and soldering an intake grate for the boat. Being this was something I never quite got with the first boat, I figured it should be the first thing I finish on this one. I pretty much traced out the intake on the brass cut slits every cm across. Then bent up the sides to form a set of guide vanes. This did three things, guides water straight into the drive(no turbulence), helps the boat track straight and protects the intake from large rocks. I then doubled the thickness of the base and vanes.

It might not be easy to see the intake, sorry it's a bit too shiny to try to photograph at night indoors. I was almost going to paint it just so you could see it. Mind you I'm not done with the intake but, its roughed out pretty good and I've got some extra metal to work with.

That looks very nice. Great job
