Most servos will work in most RXs. The exception I am aware of is Airtronics. As far as Futaba,JR,Hitech,Spectrum. Any of these companies serovs will work in any of the RXs. As long as you have them plugged in correctly. If you plug them in wrong, they don't run back words, they just dont work. As for as your channel number. It makes no difference to the RX.
