Re: [Phys-l] unusual areodynamics



RC helicopters can do some crazy things, too.

Hobbyists are doing some wonderful stunts using modern lightweight
clockwork.
I can imagine that this example has some useful help from 3 axis
accelerometers and gyro inputs to controls.
I find it particularly impressive when an RC helicopter can summon
stability in space at hover - hands off!
