I'm just finishing up my RV-12. Calibrated the autopilot servos as per the manual and that worked fine. However, the trim indicator on the SV panel is grayed out, as is the Trim calibration menu option in the Setup>Hardware Calibration>EMS Calibration menu. The RV-12 uses a Ray Allen servo for the anti-servo tab on the stabilator. Skyview is apparently not seeing the trim setting. The trim switch on the panel works OK so the servo is getting power, but I assume that means that one or more of the remaining servo wires has a fault - possibly at one of the crimped on connectors? Any advice or suggestions?
