I’m having big problems setting up twin servos for my elevator half’s on my Seagull Extra 260 (90). This is the first time I’ve tried to use two servos to control a control surface. I’m using one channel through a splitter/reverser to Hitec 645’s. First of all the servo arms will not line up. One is off about a half a servo arm tooth. It’s either too far one way or the other if I rotate it a tooth. Now if I line up the elevators at neutral, one half travels further than the other at the limits. I’ve tried using two channels on my JR 6201, but the trim only works on the elevator channel and not on chan. 5 or 6. I’ve tried to compensate by moving the control horns to different distances. The plane flies OK, but the elevator causes rolling as is. A tight loop goes into a tight roll.
Am I going to have to go with digital servos?
