I have been concerned with the flyaway issue, so I did some bench testing. I took off the props and pushed the throttle around. In the NAZI software the throttles look great and always comeback down from full throttle. When I then disconnected from the computer and did a full throttle, after about 4 seconds and release, the throttle stays as full throttle even though I have released to center. It also will full and left or right with full throttle if I go to the corners. I thought it might just been that it was in the house with no props, so I had my brother hold on to it. I pressed full throttle and sure enough it never stopped spinning at full throttle after I released it to senter. It is like it is stuck.
