The I.F.O. Aerobatic R/C Slowflyer - Super cool plane!
As I understand it, this can be flown indoors in a gym, or outside in under 7
MPH winds. With the right flight pack, it can hover on its prop and is almost
indestructable. You could sit on your back porch and fly this around your
kids.
And there are IFO model files for FMS if anyone wants to try them out.
