Not exactly sure what it is you're asking.
Nitro or electric, and what are you trying to accomplish?
I just reread your question...are you setting up a Model Avionics Throttle Max limiter or a Throttle Jockey governor?
The limiter control wants to use RX Channel 7 as the default. Enable the Governor function, assign it to the flight mode switch (unless you have a burning desire to use a different switch to make it go) then set the limit values for each mode in the governor menu. You will need to calibrate the Throttle Max to the TX throttle stick, too.
