 Limit setting

Move the rudder stick to the left and right and
perform adjustment at the Lmt screen so that
the servo operation angle becomes the maxi-
mum value at which the servo horn does not
strike the linkage.

*When flying, the servo horn does not move beyond this set angle,

thus protecting the linkage. However, if the limit setting is too low,
gyro performance will be effected.

*In this mode, only the stick operates; the gyro does not operate.

 Gyro gain setting (tentative setting)

The initial gain of the GY601 is 100% for
both G1 and G2. When setting the gain from
the transmitter, leave it at the 100% reference
gain.

Make the following value the gain setting criteria.

A setting example when a T9Zwc series transmitter was used is
described below. When using another transmitter, see "Remote gain
function" on page 21.

(T9Zwc transmitter setting)
•Call the transmitter GYR setting screen.
•Adjust the gain when hovering to 90% at the AVCS side and 10% at

the normal side on the transmitter screen.

•Set the gain in flight to 80% and 20% for the AVCS and NOR mode,

respectively, on the transmitter screen.

•At this time, the GY601 gain display becomes 80% for hovering and

60% for flight.(*1)

(*1) In the case of the T9Zwc GYR function, GY601 gain is 0% for a

transmitter setting of 50%. When the gain is set above 50%, the
GY601 operates in the AVCS mode and when the gain is set below
50%, the GY601 operates in the normal mode. The gyro gain
changes 2% for every 1% gain change.
