You're right about sticking something onto a control surface. I like the idea of attaching the roll control to the trailing edge of the stub wing but don't like the idea of attaching things to the elevator. Cutting another trim tab in the other elevator and attaching the servo to that would seem like a better idea rather than using the tab that comes with the TruTrak. Still playing with the idea of how to do it but it might be moot anyway - TruTrak, sad to say, is no longer the successful, busy operation it once was. They're behind on orders and repairs and their company user forums, once heavily trafficked, are now vacant. Doesn't look good. I'd sure like to get the control head and the servos for this autopilot and adapt it myself. Mike KSEE ____________________________________________________________ Citi ThankYou??
