Use

The following describes basic use of the GY501. Note that in the
AVCS mode, operation is somewhat different than that of a conven-
tional gyro.
Initial setting
1) Set the gyro operating direction at the GDir screen.
2) Set the servo operation limit range at the Lmtx screen.
- Adjust the servo travel so that it is within the linkage range.
3) Set the gyro operation mode at the Mode screen.
- To use the GY501 in the Normal mode only, set to "Nor". To use the
GY501 in the AVCS mode only, set to "AVC". When switching
between the AVCS mode and Normal mode, set to "CMT".
- When using the GY501 in the "CMT" mode, the AVCS and Normal
mode sensitivities must be set while hovering and during flight.
Therefore, a transmitter (T9Z, T8UHsuper, etc.) with a gyro mixing
function is necessary.
The following shows how to use the GY501 in the CMT mode.
4) Adjust the gyro gain.
- The GY501 initial sensitivity is 100% for both the G1 and G2 gains.
