the neutral trim position set in the Normal mode. This memorizes the
new rudder neutral position in the GY501. When the transmitter has
a function that allows trim setting for each flight condition, such as
the T9Z, the AVCS mode trim position is fixed and this operation is
unnecessary.
Note: The rudder neutral position is memorized inside the GY501.
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 with the transmitter in the ON state. This memorizes the
new rudder position inside the GY501.
