RE: GP GEE BEE
I also wrapped the outer tread area with electrical tape. when you compress the wheel up in the wheelpants like a rough landing the foam wheels grab like brakes, but with the tape it slides along the inside of the pants...so hopefully it will help. I know on some small electrics the tape on foam wheels makes a HUGE improvement on handling on the petrolmat runway.
I know the geebee is a problem child on landings, but it was ON THE LIST of planes that must be flown...I never planned on it hanging around forever !
