FOR SAFETY
When the rudder neutral position was changed by the linkage,
the rudder neutral position in the AVCS mode must always be
re-read before use.
Re-reading method:
Turn on the transmitter in the AVCS mode, then turn on the
gyro . Or quickly switch (interval of within 1 second) the
remote gain channel switch between the AVCS mode and
Normal mode at least three times and switch the AVCS side
with the transmitter in the ON state. This memorizes the new
rudder position inside the GY502.
During initialization, the message “-Hello-” appears on the GY502
LCD screen.
Do not move the helicopter until this message disappears (in
about 3 seconds).
Also, do not move the transmitter rudder stick from the neutral
position during this period.
Precautions When Turning on the Power Switch
Always check the direction of operation of the servos.
If you attempt to fly the model when a servo operates in the wrong
direction, the fuselage will spin in a fixed direction and enter an
extremely dangerous state.
Avoid sudden temperature changes.
Sudden temperature changes will cause the neutral position to
change. For example, in the winter, do not fly immediately after
removing the model from inside a heated car and in the summer, do
not fly immediately after removing the model from inside an air
conditioned car. Allow the model to stand for about 10 minutes and
turn on the power after the temperature inside the gyro has stabilized.
Also, if the gyro is exposed to direct sunlight or is mounted near the
engine, the temperature may change suddenly. Take suitable mea-
sures so that the gyro is not exposed to direct sunlight, etc.
