RE: Exceed RC Rx question
Re: matchups
No, they differ sometimes greatly.
Your best bet is to plug a loose servo into the receiver and a battery on the highest channel.
Then power up the TX and see which stick moves the servo.
Once you've determined that, move the servo to the next port.
You can do this with the RX powered up, as long as you do not reverse the orientation of the connector.
I do this all the time.
