No problem Bill. I hadn't thought that through in some time, just had been taking it for granted for a while I guess, so really hoped I wasn't getting too far off.

What's amazing is that lots of folks don't understand the underlying reasons for right thrust. Many think it is to counteract the torque of the engine, but that would be roll-wise, not yaw-wise.

Another reason for right thrust that I have seen explained is that as the propwash curls towards the tailfeathers, it usually induces some left yaw from pressures on the rudder I guess.

Thanks for not ejecting me from the forum....:-)
