RE: Need help with Hitec Supreme Rx...
As CP140 suggested Rx's could care less. The difference is in the the TX and different brands definately use different port assignments.
As you mature in the use of your Tx you will know which function plugs in which channel # and it makes no differance what the Rx brand is or how it is marked for aileron,elevator, rudder or throttle etc. if it is not the same make as your Tx.
Piper_Chuck outlined the very simple procedure if you forget what your Tx's port assignments are.
