Despite the correct gear ratio and motor pole count, the Spirit GT shows around 400 rpm too much with a Heli-Jive 120+ HV. In EdgeTX with FrSky F. BUS, around 2200 RPM is displayed. However, the Heli-Tach app determined around 1800 rpm, and you could also hear that the actual speed was significantly lower than what the telemetry showed. The gear ratio of the heli is 9.23 and the divider for the motor is set to five with an Align 750mx with 10 poles.

Hello,
I don't know the Heli-Jive exactly because I have no one -
But I have an suggestion for you - If you have setted the correct Motorpoles and the gear ratio in the Heli-Jive you can maybe manipulate the RPM-Telemetry-Sensor in the transmitter, test it with changeing the multiplier, if its possible or you can change the gear ratio in the telemetry settings in Spirit Software -
I can't think of anything else to say -

You can only try it - I hope this helps -

Regards
