I understand the theory of P factor, torque, gyroscopic precession, spiral propwash. All 4 cause a plane to pull to the left on takeoff. (Actually, precession makes a plane pull one way when the tail lifts and the other when the plane rotates). In a geared engine though, P factor and spiral propwash will be opposite the normal direction. But torque and gyroscopic precession will be offset by the prop turning opposite the crankshaft. I was just wondering what the net effect is. Guess I'll find out in a few months, with a little luck. Hope to be ready to cover by summer.
