flight conditions. You can set different delays
for aileron, elevator, and rudder. The delays you
set apply to all flight conditions. We recommend
trying very small values for the initial settings, say
5 - 10%. A 25% delay is about a half-second
transit time between neutral settings.
22. Gyro sensitivity should be controlled
with the CH5 switch. High is normally used
for hovering, and low in other flight
conditions.
You may use the Hovering Pitch and
Hovering Throttle functions for fine trimming
changes due to humidity, etc.
This concludes the example setup procedure
for helicopters. Be sure to browse through the
pages following this example to see what other
menus are available for helicopters, such as
Hovering Throttle and Pitch knobs, OFST, ACC,
DELAY, and INVERT CROSS. You may use a
mixer to adjust gyro sensitivity, or to enhance
flight capabilities or to correct a response you
don’t like. Again, we recommend you set up and
trim in the Normal flight condition before setting
up the alternate flight modes.
This procedure assumes helicopter is trimmed for hovering. Trimming must be done
in near-calm conditions. Repeat tests several times before making adjustments. If any
changes are made, go back over the previous steps and verify, or further adjust as necessary.
