split elevator with 2 servos and 8103
I have an 8103 and a plane with a split elevator with one servo on each half. I programed an elevator to aux 2 mix. It works fine but the half of the elevator that is on Aux 2 will move if I move the aux 2 knob. Is there any way to turn off this knob? If I accidentally move the knob in flight or didn't notice it was moved prior to taking off it could cause a crash.
