Flight Adjustments
1) Turn on the transmitter power, then turn on the receiver power.
- Never move the model or rudder stick during the 5 seconds the
"INIT" 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 GY501. 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. Memorization
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.
- In the AVCS mode, when the sensitivity is lower than the suitable
sensitivity, operation that resembles conventional hunting or opera-
tion that seems to be the opposite of operation of a conventional gyro,
such as a slight drifting of the tail when the sensitivity is high may
occur. Therefore, use a method that finds the suitable value by
checking neutral suppression and pirouette stopping by raising and
lowering the sensitivity.
