unit must be kept at a minimum.
B. When installing this flight stabilizer, we highly recommend that you install it with the supplied
vibration absorbing pads (dampers).
C. The algorithm in the FY-31AP compensates for normal levels of flight vibration. However, if
the vibration experienced by the unit exceeds the acceptable level, it will not work normally or
may even stop working altogether.
D. To keep vibration at a minimum, install the FY-31AP away from the engine or any other
vibration sources.
E. The included shock-absorbing pads will meet the damping
requirements for electric powered aircrafts and most gas / nitro
planes.
F. The FY-31AP is supplied with the double-sided foam padding
dampers. Please use them as shown:

Checking for Vibration Levels
Even with the shock absorbing mount, your aircraft installation may not meet the damping
requirements of the FSS. To confirm correct vibration damping, please follow this procedure:
A. After connecting all wires between the FY-31AP,Receiver and ESC, install the unit as
recommended (ensure correct orientation).
B. Run the plane engine or motor at different throttle levels. DO NOT TAKE OFF.
C. Move the throttle level to different positions and maintain it for 20 seconds at each position.
D. At each throttle position, observe the state of the red LED light. If it stays OFF, that means your
vibration level is acceptable.
E. If instead the red LED lights up bright and staysON solid, then the vibration dampening is not
enough. You will need reduce the level of vibration on your aircraft, add additional dampening
support or change the installation location.
