H9 j3 CUB-pOSSIBLE TO TAKE OFF?
I have the GP Cub with an OS52 on it. Os recommends you use a 12-7 and thats what I have on it. The way I see it your not getting enough speed on take off and applying to much up when it gets in the air. You have to fly it scale like. A real Cub took awhile to gain altitude.
