Cool! :) If I ever won the lottery I would probably build this one:

My L-50 Fighter (Blue off course) ;)

Actually, I used to call this one Bluebird until I built the SR-100.

very cool model :)

I have built a scale rocket boat but its only 25cm long, and runs on candy rocket fuel (KNO3/Sucrose), I haen't been brave enough to try a rocket motor and the boat together yet, I'm waiting on getting an alloy motor case made, some of the test motors casing failed which wouldn't be good in a balsa wood boat lol
If it works then plan is to go bigger, I'd like to use a pulse jet but they are pretty much banned on water in the uk

Impressive, you seem to have some big plans. If you are using rocket engines, have you made any calculations on how fast it would go? :)

the boat's weight is about 0.1kg, with a motor installed it'll probably be 0.5kg, so it doesn't need a great deal of thrust to get it moving,, a lot depends on whether it'll get up on the plane to how efficent its going to be, the best I've achieved power wise was about 1kg of thrust for 5 seconds
There's a lot better fuels to use, it just looks very dodgey buying them.

If your interested here's the boat I build, mines a bit smaller and adapted to use home made motors rather than the very expensive Jetex ones., if it works I want to buy a hydro kit and have rc control, mine you just light the fuse and hope you can get it back lol
