Lynn: Funny you should mention this. I was just testing my new Turn Coordinator yesterday in my coupe (actually an Alon with 3 controls) and was making a mental note of how much rudder was needed to keep the ball centered in slow-speed full-throttle climbs. In 80MPH+ climbs and at cruise no rudder input was required, but below 80, right down to 50, an increasing amount of right rudder was needed to center the ball. At 50 it took almost full deflection. This is exactly what theory would predict - read "Stick and Rudder."
When you have only two controls you have to bank to
counteract the effect of inverse yaw on directional control
- you can not eliminate the resulting slip because you don't
have rudder pedals. The plane can only be set up to have
perfect coordination of controls at one speed - in the case
of the coupe, that's at cruise. I suspect that "other
people don't have the problem" because they don't have a T&B
in the plane, or they just bank and accept a mild slip and
don't notice it.
BTW, you should notice the same effect in slow speed
descents as you do in climbs. In short, it's perfectly
normal.
