Hitec 5735
I have ten 5735's. . .one lost an amplifier a few weeks ago, on the bench while setting up a plane. . no problem, just shipped it off to HiTec for repair.. all in all a good strong servo and very reliable. I've had a pair in a plane for 2 years now. . never a problem with performance, and after 300 flights the gears are still pretty tight.
