Is there any way to cause the annunciator LEDs that accompany the Ray Allen trim servos to track servo position accurately, or skew their center indication even if the servo is nowheres near center?
Out of the box, these things are very non-linear, and the center indication could find the servo considerable distance either side of center. Also, I know that on RV-7s (perhaps others) that far more elevator trim tab down deflection (nose up) is needed than up deflection. Thus I'd like to set the servo's mechanical position so that most of it's stroke, say 75%, is dedicated to down deflection with the annunciator LED next nearest one end of the display lit when the tab is in trail.
Any possibilities?
