Hi! Kayaba autogyro.

When take off,
1.Turn the rotor until 180 r.p.m by engine power.
2.Cut the power to the rotor by crutch.
3.Increase propeller thrust to move forward direction. The rotor rotate naturally.
4.Take off by free rotate rotor lift.(240 r.p.m)

She could hover while angle of attack was 15 degree.
The autogyro is a wonderful vehicle.
Number of production：98(1941 to 1945)(1 gata were only 20,because Argus engine had over heat problem,nevertheless low drag.)
