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
GY611.
· Never move the helicopter or rudder stick during the approximately three sec-
onds 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 link-
age 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 rud-
der 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 GY611. Therefore, always perform the fol-
lowing 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. Memorization and updating is executed only when the sen-
sitivity switch is in the AVCS mode position.

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 GY611 gyro gain adjustment screen, or by increasing the End
