Hi Rick,

A friend of mine once had an Orbit ECU (although not the auto start version you have) and, as I remember, there were 2 connections to the receiver. I think one was the throttle channel, and the 2nd connection went to an on/off switch on another channel... If that's the way this one works, you'll need 2 of those little servo testers and you should be good to go.

Good luck on the maiden flight of your test bench!
