Well I have flown my Sukhoi a lot. I flew it so much on Sunday that the covering started to come off in flight. It was just the red covering on the front of the left wing that was starting to peel off.
I was wondering what is the best way to get it into a good flatspin. It will do a pretty good blender. But I can not get it into a flat spin. After a couple of more flights we are taking the spring crank out out of the gt80 and drill holes in the mufflers. Right now it is pulling out of a hover. I believe this motor is going to be good for the job. I have not had one screw to vibrate out. The gt80 to me sounds smoother than any other engines.
