Pitts Special Prop Governor


The prop govenor doesn’t give full prop pitch at full the throttle until some way into the takeoff ground roll. This causes a massive yaw to the left as the prop goes from 2,000 to 2,500 rpm. This feels like a bug.

It is a serious bug, but the sudden yaw is due to the tailwheel loosing contact with the runway.
If you maintain a bit of aft stick, you can avoid this problem.
