I lost one in a losi on the steering, and one on my new Mugen on the throutle. My friend lost one on the steering and throutle on a losi. I am glad you are having such good luck with the servos. I resently talk to a Hitec rep that had told me that even Adam Drake was having throble with the 7940 he switched to the 7950 and has had no problem sense switching. My e servos had nothing to do with the gears they both had motors go out on them. My friend had one that was a motor issue and the other could be a gear problem. PS I had 5955 servos in my losi for over 6 months with no issues even runningwith Lipos. Put the 7940 servos in and lost both within probable two months. I am not saying Hitec is junk, as that's all I run in my qiant scale imac planes love them.
