Check to make certain that the wires on the servos match the input wiring for the co-pilot. Airtronics used to have a different wiring arrangement from everyone else. I don't know if the new ones are different, or not.

If all the wiring matches up, i.e. signal wire, power and ground wires in the same locations between the co-pilot and the servos/receiver all should be well. The co-pilot was designed to work with any radio.
