Geistware, I think when you get the correct amount of right thrust in you will know it right away. More than likely when you are at that point you should be able to change props around without noticable difference in yaw. Of course, some rudder corrections will still be necessary.

I'm not sure I could learn to live with a plane that went a little right on takeoff. That would be like having to push the stick forward a little to land. Some things just go against the grain.

Keep us posted.
