I have a brand new 9254 that was part of the GY401 combo set. Purchased from tower hobbies. While installing it and setting up the arms I noticed felt a wierd notchiness in the servo when the wheel was turned. it seems to happen in three spots. I had a pro a LHS take it apart to see if any gears were chipped but they were all intact. It just does not sound right tome when connected to the Rx and rudder input is given. I am concerned becuase I intend to put this in a Scale aircraft and dont want an inflight failure. THis is a brand new servo !
