Build a FT type of plane around the notion of a prop that spins fast enough that part of the prop goes supersonic. I know a supersonic prop loses efficiency, but that isn't the point. The point is to build an electric airplane that flies and is really noisy because the prop is supersonic. I have seen and heard full scale planes with supersonic props and I can assure you that it is almost unbelievable.
It will take a high kv motor driving a fairly low pitch prop, of course, but it will also probably take using more cells than a motor is really designed to use. The prop will have to be on the small size so the motor isn't overloaded.
I'm thinking an F-22 type plane with mid-ship motor to maximize the noise. A bigger plane would be noisier too. And, yes, it has to be electric so we know all the noise comes from the prop.
