 Throttle Servo Linkage Precautions

· To effectively use the governor, observe the following precautions when connecting the 

servo linkage.

· Make the servo operating range as wide as possible.  Make the throw of the transmitter 

EPA (ATV) function and AFR function as close as possible to 100%.

· Fly with the governor turned OFF and adjust the needle so that the engine smoothly 

reacts to movement of the transmitter stick.

· If there is a point at which the reaction of the engine is considerably different due to a 

too rich or  too lean mixture, the governor may not operate to its maximum potential.
