I have my first true giant scale plane, a 1/3 scale Citabria. 131" WS, 38 lbs. Bought used. Installed a friends G-62 with Pro Zinger 22-10 to see if that would be enough engine. In general, plane flies great, and very scale like. So, I purchased a used Sachs 4.2 (a little more power is always good) and am in the process of installing.

Set up the G-62 with 2 deg right thrust, 0 deg up/down (as best I could). Thought I had the right thrust nailed because plane needs little if any rudder correction from idle to full power. However, the adverse yaw when using ailerons only is really powerful on left banks, much more tame on right banks. On left aileron banks, the plane will actually go right and climb. I understand that coordinated rudder is necessary, and is part of the fun of learning to fly the plane in a truly scale like manner. The problem I want to try to correct is the difference between left and right turns. Very stable and linear in right turns, but in left turns, using left rudder, a little too much rudder makes the plane bank (roll) way more than the stick movement should. When trying to tighten up the turn with more rudder, actually needs some opposite aileron to keep it from banking too much. Right turns don't do this - just bank with both aileron and rudder, and then hold enough rudder to keep it turning. I've been told this is just due to engine torque, etc.

So - question is - is there a balance between right thrust and the difference in left vs right turns? Should I back off the right thrust, and put up with a little pulling to the left under power? Would that help even out the turns? Or is this just the way I should expect this plane to act?
