Hi, I finally got back to work on my ST. Aileron servos are mounted but now I need to know the distance (in mm if possible) from the servo arm screw middle to the last hole on the servo arm for all the recommended Alu. servo arms Aileron #HAN3574 , elev. #HAN3578 Rudder(tail mount.servo)#HAN 3578. They don't have any H9 3d servo arms at my LHS. so with you guys help I can find a proper replacement. Oh make sure the metric measurements are done with a ruler that represents the true measurement values. I've had rulers before where the Inch scale was correct but the ruler company just guesstimated or rounded off on the metric part and it was of course not very accurate for fine measurements.
Thanks,
Mike
