ing the problem. If you feel everything is set
up correctly and that the helicopter is vibration

new location away from servos, ESC and drive
motors.
gyro systems. Even though the CGY750 gyro
sensor is the most vibration resistant gyro sen-
sor available, eliminating vibrations will always
improve performance. Throughout extensive
testing it has been found that the CGY750
gyro sensor performs best when the sensor is
mounted rigidly to the airframe. This is mainly
-
ommended to avoid using soft foam pads as
this may allow the gyro to bounce around on
the roll and pitch axis, causing instabilities and
possible loss of control during flight.
All components of the helicopter must be bal-
anced and operate in a smooth manner. The
newer gyro sensors are so sensitive (and
extremely accurate) that even something as
simple as a bad ball bearing can cause enough
vibration to cause the sensor to read incor-
rectly. Main and tail rotor blades must also be
perfectly balanced. Ensure that your engine is
running smoothly and properly tuned. If you
feel that all of the criteria has been met, then it
is recommended to relocate the gyro sensor to
a different position on the helicopter and test fly
again to look for improvements.
