（When number of rotations goes up at the time of Throttlehold ）

*If the speed is increased at throttle hold, the governor and transmitter operating directions will not 

coincide. In this case, match the operating directions by reversing the polarity of "CH8".

A governor is made up of a set of sensors which 

read the RPM of the helicopter’ s head, and a 

control unit that automatically adjusts the throttle 

setting to maintain a constant head speed 

regardless of changes in pitch of blades, weather 

conditions, etc. Governors are extremely popular in 

competition helicopters due to the consistency 

provided. 

How does it help in helicopter setup?  The 

governor eliminates the need to spend large 

amounts of time setting up throttle curves, as it 

automatically adjusts the engine’ s RPM to 

maintain the desired head speed.
