I have planed to make a small engine for my RC. I plane to use clay and (balsa layers) wood for structural support. I know clay is relatively heavy, so I only plan to use I tiny amount for the wind tunnel of the plane. Like one other person had mention, I want to use a "cold" jet. I plan on spacing the fan blades apart and using a reverse nozzle to compress/focus the air and they use the rocket nozzle on the other side. Over all, air way should short. What's even more wacky, is that I plan to do this with electric power... and I hope it will outlast all other Fan Duct planes. For electricity, I plan to use a combo of LiIon batts and Solar panels. Am I far fetched? If you think not, then please help... I would like have some websites or something to look at. Thankyou:shy: PS: I give you permission to laugh if ya want.
