whatever you use, make sure it centers well. I recently installed a Hitec 5625 \which I used on a throttle of a gasser and it wouldn't center worth a hoot. I threw it out and put a spare 5955 in. It centers now for sure. it would probably break the wire if the gear got bound... but its what I had. I used a hitec 985MG before and it worked good, as well as the already installed JR 579 on my new Kingcat and Rookie(RIP)
