Fuselage Maintenance Precautions - FUTABA GY601 Instruction Manual

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.
Avoid sudden temperature changes.
Sudden temperature changes will cause the neutral position to change. For
example, in the winter, do not fly immediately after removing the model
from inside a heated car and in the summer, do not fly immediately after
removing the model from inside an air conditioned car. Allow the model to
stand for about 10 minutes and turn on the power after the temperature
inside the gyro has stabilized. Also, if the gyro is exposed to direct sunlight
or is mounted near the engine, the temperature may change suddenly. Take
suitable measures so that the gyro is not exposed to direct sunlight, etc.
Check the remaining receiver/gyro/servo nicd battery operating time
during the adjustment stage and decide how many flights are remaining.
Never use the transmitter rudder trim in the AVCS mode.
When the rudder is trimmed during flight, the neutral position will change.
When using the GY601 in the AVCS mode, set revolution mixing to
OFF.

Fuselage Maintenance Precautions

Use a tale rotor drive tube or other part with a high torsion perfor-
mance for the tail drive.
Take the strength of the tail into account during inspection and adjust-
ment.
The amount of improvement of gyro performance has a considerable effect
on the fuselage vibration level or the size, type, linkage method, looseness,
etc. of the tail rotor.
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 and switch the AVCS side
with the transmitter in the ON state. This memorizes the new
rudder position inside the GY601.
