Hey, one other thing about "turning left then crashing"....

I didn't mention this at first because I didn't think it was likely that you could have changed this, but with all of your crash repairs, did you ever have to do anything to the firewall or motor mount area? The motor is installed so that the prop is angled down and to the right (referred to as down thrust and right thrust, or collectively "thrust angle"). This is intentional and is neccessary to offset torque and what we call prop effect, altogether the dynamic and aerodynamic forces of a spinning propeller. If you somehow mount the prop so that it is in-line with the fuselage, the plane will tend to turn left and pitch up when you apply throttle, which could ultimately result in a corkscrew into the ground
