NO DOUBT, IT WOULD!

Diablo...So are you saying that the fact the place demostrates p-factor means it's out of trim??????

JEEZ! I guess we better put spacers behind the engine mounts of full scale aircraft so they won't experince left yaw due to p-factor. While we are at it, we can do way with counter rotating engines on twins just by installing spacers on the non-critical engine. I wonder why none of the engineers ever thought of that?

Huge difference between out of trim and normal aerodynamic characteristics.
What's he design call for and where is the thrust angle now?
Does it exibit left yaw when slowing down on a vertical climb or during the whole up-line?
Were you flying it directly into the wind when you noticed you had to add rudder?
