One aspect not given much attention in this thread is propeller choise. The plane I fly mostly right now is Diablotin Std with Irvine 72. It is basically a very easy plane to hover.

However, if I use 6 inch pitch propeller (tested APC 13x6 and 14x6) it becomes difficult to keep in place. Needs 3/4 power. APC 14x4W transforms it -- very stable, hovers at half throttle, need very little right aileron to prevent torque rolling.

The moral: use ow pitch propeller at least when learning the basics.
