SBD-1 problem maybe
 

I have 3 SBD-1 in a small B-17 1 in each wing and one running to the tail. The problem is in the left wing. 3 servos, 2 throttle 1 aileron. I can not adjust the end points or subtrim the aileron. The right wing works fine. The left servo is on channel 6 and moves in the correct direction and can be reversed. I am out of ideas as to the problem. Servos check fine so wonder if there is a problem in the decoder cable. radio is the 14SG. I have other planes on SBus and everything works fine.

Unlikely it is the SBD itself. The SBD only allows you to set channels, all the other function are accomplished in the radio. Let me know how everything is assigned in the function menu.

Problem was solved. Somehow that lead didn't get set right. Appears it was on channel 1 instead of 6. explains why it would move but wouldn't set. Should have double checked that first but it is always the simple things you overlook. Thanks

Well, there you go. Like you said, it is always the simple things. Happens to me all the time!
