Hi Meikleour
We need an aerodynamics expert (which I'm definitely not) to sort this one out! I seem to recall that there are several reasons for variable engine power causing yaw changes, which rudder inputs oppose. On a single-engined aircraft one of the causes is spiral propwash past the fin-rudder but of course that doesn't apply to a multi with wing-mounted engines. Or does it? I wish I could remember . . .
