Hi!
Have been in this sport/hobby for 34 years and I don't use a mixed throttle /rudder on any of my planes! Be it sport planes, pylon racers, scale or 50cc gassers! At take of all my planes track straight forward!
When newbies complain about a plane not tracking straight they always tend to think about torque /P-factor, but its not!
The reason some planes (mostly belonging to newbies) do not track straight is that the wheels on their planes are not set up correctly!
I honestly do not want to begin any kind of disagreement but, if someone reads your post and believes it then they will be taking away an incorrect set of facts. So that I don't repeat my previous posts I will simply state that they are accurate and correct. All single engine propeller driven airplanes yaw to the left (for counter clockwise rotating prollers) when you apply power or slow down while keeping the same power - for the reasons that I stated and it has nothing to do with how the wheels are set up. This occurs both on the ground and in the air - always. I respect your 34 years in the hobby. I soloed a Carl Goldberg Senior Falcon powered by a Veco 50 in 1969. Once again, let me suggest that a good pilot training ground school manual/book could be very helpful in providing another source to understand the yawing effects caused by the propeller.
