Thanks Tony We will try them.
Scott has the plane now , I`ll get him to try it.
The Small props seem to work so well , I could hardly ask more of the combo. breaks and throttle were a perfect effort. I did fly the airplane with the Larger props but the Brakes were way to much, and I had to stay in the throttle more especially in the back of loops, eights ect.
I did not change gear however.
