I can't find a text/instructions for mechanical retracts. Should the push rods from the retracts go as straight as possible to the servo arm, or should there be a slight bend at the arms? My retracts, with a hitec retrac servo grunt and groan about mid retract and have often hung up. I quickly lower them and keep on flying. Have pulled the wells and cleared all binding. The retracts themselves have no binding and the servo is smooth. This is a hanger 9 P51. My email is [email protected]. Thanks to all
