Use Parameter menu point I to change the response of the RPM Governor control. This determines how fast and how far the system will open the throttle when the rotor rpm changes. Ideally the response is set as high as possible. If it is too low the main rotor may speed up in unloaded conditions as the system reduces throttle to slowly. Also the RPM Governor will only increase throttle very cautious when the rotor is loaded, so that the rotor rpm will drop. If on the other hand the response is set too high, the throttle may stutter audible and/or the motor rpm will kick in very hard and overshoot if the rotor head is loaded. This will make the rotor headspeed even more inconsistent than with a lower setting. The height of throttle response highly depends on factors such as heli size (blade size), motor power and performance and/or the throttle reponse behavior of the speed controller (when flying an electric heli). If you need to adjust the throttle response, we recommend to start with the lowest value and increase stepwise just until you get the most consistent rotor head speed. Having a heli with good motor power and/or a fast responding speed controller (on electric helis) typically allows to have high throttle response values (up to "very aggressive" setting) which will give very consistent head speed. Helis with not so much power (small nitros, gasser, scale helis) prefer low throttle response settings for a softer throttle management.
The choice is made by moving the rudder stick into one direction until the Status-LED lights in the desired color.
