The Governor of the AR7210BX calculates with the rotor head speed of the helicopter. So as shown at the transmitter setup step of GOVERNOR MENU you can preset the desired head speed very easily and the AR7210BX will try to maintain the given rotor headspeed as close as possible. Thus the detected rotation speed of the motor can be converted into rotor head speed, you must specify the main gear ratio of the helicopter.

The gear ratio should be specified in the instruction manual for your helicopter. Especially with electric models it will vary depending on the motor pinion used. For helicopters with a single-stage gear drive the reduction can be calculated by dividing the number of pinion teeth from the main gear tooth count.

Example: Shape S8 - Main gear tooth count 130 teeth / 15 tooth pinion. Gear ratio apprx. 8.65:1. F - Status-LED purple flashing, G - Status-LED red, H - Status-LED purple.
