Initialization
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
AVCS mode operation is based on the rudder neutral data stored in
the GY502. When using the GY502 for the first time, or when the
internal reference data and the transmitter neutral position differed
when the transmitter neutral trim was adjusted, etc., the rudder
neutral data must be read again.
[At power ON]
When the power switch is turned on, the GY502 automatically
obtains the reference signal for AVCS function correction and
initializes itself.
•When the power was turned on in the Normal mode, the rudder
neutral position already memorized in the GY502 is not updated.
•When the power was turned on in the AVCS mode, the rudder signal
at that point is memorized and updated.
[During use]
When the rudder was re-trimmed in the Normal mode and the new
trim position also affects the AVCS mode, the rudder trim neutral
position must be memorized in the GY502.
