Thanbks to the great advice I received at this site I'm now able to get me H9 J3 Cub safely off the ground. It flies great but the problem is that it's a real floater. I have an OS .46 FX in it and have it idled down pretty slow. I am trying to make approaches as low as possible but have to keep clear of trees. Right now I have an APC 11x6 prop on it. Will changing prop size help as a brake effect. Any suggestions? Also have a CG Ultimate ready to get into the air. It has a ST,75 for power. I'm not into extreme aerobatics ie: (not able) but would like just all round good performance. Any suggestions on prop size would be appreciated. Thanks.
