Bryan Thanks for the comments, interesting autopilot you have !

You are quite correct, when we dial out the wing drop with a trim tab you
need to apply right rudder (just a touch) and the situation is extremely
dependant on pilot / passenger ratio.

However all the trim tabs and a touch of rudder decays all the efficiency we
have tried to obtain !!

ATB

Tony.
