Other Hidden Inputs? (also searching for in depth vizzy tutorials) (Update: Solved i guess)

I'm currently making an aircraft with two gauges displaying the RPM of the two motors but for the life of me cannot find the option in the craft information list.

The farthest I've gone is using Command Chip.FlightProgram.Rotator that is set to the throttle setting but It is essentially the ideal RPM output instead of the actual RPM in the craft part information during flight. Just recently I discovered I can use FlightData.(insert flight data here) but it focuses on the overall craft information and not on that motor.

anyone got suggestions? references? tutorials?

Update: I found. its in the JNO XML guide that i forgot lmao
