2 blade 42 inch rotor R/C gyroplane

This is the same gyroplane from the other videos. Only difference is the rotor is much larger. It started out as a 3 blade 24 inch rotor to a 2 blade 24 then a 2 blade 30 inch with the 24 inch blades and now 42 inch 2 blade rotor with 18 inch foam, carbon fiber, tape blades. 6 inch hub bar. When I changed to the 2 blade rotor I also cut off the elevator and made the head capable of fore and aft tilt so now I have a full dc head. I also cut the H stab off in a test but determined that some H stab is good so then added a very small 2X5 inch (10 sq in) one onto it.

This is the best flying one yet. As you can see it has a great climb for a 21.5 gram brushless out runner turning an 8X3 gws prop. Sink rate is great also. Servos are HS 225 MG servos. They are heavy but the large rotor and small power seems to work great. I fly it at about 60% throttle or 5 amps in cruise. It never needs full power to climb well.

I have not enlarges the V stab at all in the test. The Gyro has the same yaw stability regardless of rotor size. It doesnt work that way with fixed wings.

You seem to have roll control, have you built a swash plate arrangement up?
