Can't find RC1 thru RC4 options in Mission Planner

Trying to set up Elevons in Mission Planner. I’ve read the instructions but can’t find any reference to setting elevons in mission planner (except checking elevons box in basic config)

It’s on the Radio Calibration page.

OK - I clicked Elevons on the Calibration page and now I get an Advanced Params page under Cinfig/Turning. That allows me to reverse the servos. Is that all there is to it?
