Mike, I just bought a Hitec 5645 from Tower Hobbies, I also have two more on order from TBM. All three slated for the tail of my GP Cap232. The one servo from Tower Hobbies has a lot of play, when I hold the case and pull back and forth on the servo arm it moves about 32th to 16th of an inch. That's wether it's turned on or off. The JR ST125MG that it replaced had no play at all. Is this normal for the 5645 or do I need to send it back for repair or tune up? This servo also has a whine to it when turned on? This is my first digital servo. Thanks, Henry
