Your instructor warns you that the Harvard trainer has a much more powerful engine than the Tiger Moth or Cornell. That means on take-off there's a much greater concern with the effects of "torque".

What is "torque" and how do you deal with it?

A. As your propeller turns one direction, the entire plane tries to rotate in the opposite direction. If a pilot doesn't use the control wheel to correct the problem your plane will try to roll to one side during takeoff

B. When the wing flaps are deployed, they help produce much more lift. If the flaps are not balanced properly the side with the greater lift will slowly try to roll the aircraft over. To counter-act this the pilot must level the flaps at the same level of deployment.

C. With a more powerful engine airplanes climb faster when the control wheel is pulled back. A trainee pilot sometimes pulls the stick back too far on take-off and the plane does a loop and crashes.
