Thanks a bunch guys. CBM, I tried the slave setup last night - and it works great.

Separately, one of my flap servos started acting up. So I tested the slave setup by connecting the ailerons to the flap channels for a moment.

WhenI connect this broken flap servo, Ican hear the motor reving in some positions, and then silent in others. Seems like the motor isn't connecting to the gears. And then whenI try to push the pushrod(you typically hear the gears swoosh), it doesn't move and there's no sound of gear motion.

Are the tiny flap servos that sensitive? Do Ineed to get a new one? Or does this sometimes happen and it'll help if Itake it apart and put it back together?

Thanks.
