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 transmit-
ter 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.
Fuselage Vibration Countermeasures
If the model frame is weak, or the engine mount is deformed or not installed prop-
erly, the vibrations applied by the engine will increase. Engine vibrations will lead
to unstable speed and prevent the governor from providing maximum performance.
Therefore, make sure that the engine is vibration free and that the carburetor provides
linear throttle control because the governor can not correct engine problems.
Use Of A Tuned Silencer
The use of a tuned pipe type silencer may cause the engine throttle response to be
substantially different from that of a normal mufer. Adjust the needle (and pipe
length) so that engine speed changes are proportional to the throttle opening. The
governor will not perform satisfactorily with a mufer or a pipe that does not allow
the carburetion to be linear.
