11. Vibration damping
A. DOS is vibration-sensitive. To optimize its stabilization capability, vibrations
reaching the 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 DOS 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 DOS 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 DOS is supplied with the double-sided foam padding dampers.
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:
(1) After connecting all wires between the DOS
，RC Receiver and ESC, install the unit as recommended
(ensure correct orientation).
(2) Run the plane engine or motor at different throttle levels. DO NOT TAKE OFF.
(3) Move the throttle level to different positions and maintain it for 20 seconds at each position.At each throttle
position, observe the state of the purple LED light. If it stays OFF, that means your vibration level is acceptable.
