Hi Rich,

Sorry about the crash. Just my opinion, but I would guess that the rotor shaft pulled out when the blade hit the stab. If you are using the SG6042 blade profile, 5 to 6 degrees of rotor head incidence is all that you need. Other blade profiles do require more incidence. My largest gyro weighs 5 1/2 lbs and the blades are only 23" long and it will lift straight up in a 7 mph wind. Based on the size of your blades, I suspect with 10 degrees of incidence, the rotors would pull the nose up and over on it's back so watch the throttle real close on your next attempt. Assuming that you have the hang angle correct, less incidence is better. The worst thing that can happen is, the rotors don't spin up. Too much incidence and you get rotor strikes or it rolls over on it's back.

Hang in there and better luck on the next attempt.

Phil
