RE: Yellow F22 Build
Well mine are not hysoled in and I flew it with a Kingtech K180 at Florida jets and I had it full throttle going about as fast as it can go many times with no problems. I was also doing some very hard high speed turns with it at full throttle and everything was rock solid.
Keep in mind I got rid of the stock horns that yellow puts on the rudders. I think these are what caused flutter and the problems with others. I used big BVM carbon horns with max mechanical advantage along with 8611 servos to drive them.
I am flying the Kingtech K170 now and I have been really beating on the plane in the air and its been perfect.
I agree this plane is very slick in a straight line unlike the F15.
