I checked out your theory that the prop affects the tail control surfaces. If you run the motor while holding the plane in hand, you will notice that it will rotate in whichever direction you turn the rudder. I can see this making it a little touchy. It does not seem to affect the elevator, though. I am currently having problems with my motor flexing up and down, throwing props, and braking motor mount plates. I am going to try rotating the motor 90 degrees to help limit this. We will see if it works! Aaron

PS Slow tick purchase was delayed due to purchase of paint sprayer. Practicality wins again.... Dammit...
