Well, if you are looking for how to use that menu, I'm about 95% sure you have to use a telemetry module on the model, and it uses that module to calculate the rpm and send that information to the receiver to adjust the throttle servo. Way more than needs to be done on newer gyros. Now days, you connect a sensor to the engine or fan, plug it into the gyro, and just set a gain value on channel 7 and call it done.
I don't have all of the equipment, and I doubt anyone else on this forum has all the equipment, to get that menu to work correctly. Sorry we couldn't help. But I can assure you, my reply and Fran's was not a "try this - try that" response. We told you exactly how we fly nitros with a governor with newer gyro's that can handle it. Have a good one.
