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 GY502 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
effective, the load on the tail is also greater.
Always perform proper maintenance for ultimate performance.
The rigidity of the fuselage tail has a large effect on gyro perfor-
mance.
Make the fuselage vibration as small as possible.
Fuselage vibration has an adverse affect on gyro operation.
