3.1.11 Gyro Sense

The gyros have two operations modes: GY mode and STD mode.
•STD mode: This mode performs general proportional control operation.
For instance, it controls the gyro so that changes are countered when
the attitude of the MULTIROTOR is changed by cross-wind, etc.
•GY mode: This mode performs both proportional and integrated
control operation. The difference between Normal mode and GY mode
operation is that where as the Normal mode only counters changes in
attitude, the GY mode returns to the original controlled variable
simultaneously with countering changes in attitude. For example, during knife edge flying, aileron and
elevator meeting rudder is normally necessary, but in the GY mode, meeting rudder is performed
automatically by the gyro.
Adjustability:
• Plug the gyro's sensitivity adjustment to channel 5, 7, or 8 of the receiver. (Selectable)
• Full switch assignable (SWITCH A-H)
• Each rate setting may be set from 0 to NOR100% or AVC100% gain. NOR: GY mode gain. AVC: STD mode
gain
• Larger percentages indicate more gain, or gyro responsiveness.
• MIX-1,2: Two surfaces' sensitivity can be adjusted independently.
GYRO GAIN Adjustability:
• When the servo hunts, the gyro gain is too high. Lower the gain until the hunting stops.
• The gyro will display best performance at a gain just before hunting occurs. Perform adjusting by flying the
MULTIROTOR repeatedly.
Precaution:
• When taking off and landing, always switch to the Normal mode. Taking off and landing in the GY mode is
dangerous.
•We recommend that you use the rudder control gyro in the Normal mode. In the GY mode, rudder operation
is necessary when turning because the weather vane effect is lost. Use the gyro in the Normal mode unless
you are an expert in rudder operation.
• And we recommend that you also set to off (0%) mode for safety as follows.
