Futaba GY611 - Manual (Page 6)

· Re-reading method:
Turn on the transmitter in the AVCS mode, then turn on the gyro . Or quickly switch (in-
terval 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 GY611.
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 suit-
able measures so that the gyro is not exposed to direct sunlight, etc.
Check the remaining receiver/gyro/servo nicd battery op-
erating 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 GY611 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
performance for the tail drive.
Take the strength of the tail into account during inspection
and adjustment.
· 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.
Since a higher gain than usual can be used then the tail rotor is more effec-
tive, the load on the tail is also greater.
