The Gyro Sense Mixing (GYR) function lets operator perform two-point gain
adjustment at each condition. Set the sensitivity at all conditions.

[GY601 Settings]

Select the gyro operation mode at the GY601 Mode screen. (AVC, NOR, or
CMT)

[Transmitter Settings]

ATV function:
Adjust both the RATE A and RATE B rates to 100%  at the transmitter
5ch(GYR) ATV function setup screen.
Gyro Sense Mixing function:
1. Select the Dual Mode (DUO) at the transmitter Gyro Sense Mixing setup
screen.
2. Set the GAIN1 and GAIN2 gains.
(The following page shows a setting example in the CMT mode.)

[Sensitivity Display]

The gain display indicates the actual gain at the GY601 normal screen
display. The following shows the relationship between transmitter and gyro
setting .
