canard pusher prop observations?
It would be most interesting if someone w/ experience w/ canard pusher prop aircraft (Rutan etc) w/ no fin in the prop slipstream, would post re yawing and rolling tendencies under power. How do they vary w/ power and airspeed? What rudder input or trim is needed to center the ball, and what rolling tendency exists once the ball is centered? What direction does the prop turn (cw or ccw) as viewed from the rear of the aircraft?
W/ the aircraft in a constant pitch attitude, it would seem that P-factor would be the only thing making the aircraft yaw/ slip. W/ the ball centered, we'd expect some rolling tendency opposite the direction of prop rotation due to engine torque.
