DJUSTMENT
Flight Adjustments
1
In the AVCS mode, turn on the transmitter power, then turn on
the gyro and receiver power. This reads the rudder neutral signal at
the GY601.
•Never move the helicopter or rudder stick during the approximately
three seconds that the -Hello- display blinks.
2
Hover in the Normal mode and adjust the rudder neutral position.
•In the AVCS mode, the rudder neutral position is automatically set,
and linkage changes cannot be verified. First, perform rudder neutral
adjustment in the Normal mode.
•Move the transmitter trim lever and reset the neutral position. When
the rudder servo neutral position has changed considerably, readjust
the linkage.
3
When the transmitter rudder trim was adjusted, the rudder neutral
data must be read to the GY601. Therefore, always perform the
following operations:
•Switch the transmitter sensitivity switch quickly (internal of within 1
second) between AVCS and Normal at least three times. "****" is
displayed on the LCD screen to show that data is being memorized.
During this operation, never move the transmitter rudder stick from
the neutral position for at least 1 second immediately after switching
the switch in the state in which the model is on the ground. Memori-
zation and updating is executed only when the sensitivity switch is in
the AVCS mode position.
4
Set the sensitivity to the position at which hunting does not occur
during hovering and flight.
•When the helicopter tail hunts, set the gyro sensitivity to a lower
value. When adjusting the gyro sensitivity, increase and decrease the
sensitivity gradually while checking.
•When the sensitivity is low even when the gyro sensitivity is 100%,
make the rudder servo horn position longer. The sensitivity can be
increased (up to 120%) at the GY601 gyro gain adjustment screen, or
by increasing the ATV amount of the transmitter sensitivity setting
channel. The actual sensitivity can be checked on the GY601 normal
screen display.
