Most modern computer transmitters will have a gyro function
built into them. If this is the case, please refer to your transmitter’s
instruction manual. Most modern gyro functions will allow you to
set the mode of operation and the gains for several fl ight conditions.
The use of these functions is strongly encouraged. Shown below is a
recommendation of settings:
If your transmitter does not
have a Gyro function built
in then it will be necessary
to use the ATV or EPA function to control the gain. The Gyro Gain
channel will generally be assigned to a switch which provides two
gain values. Simply set the ATV or EPA for the gyro channel to the
desired gain value and set the Gain Switch to the desired mode of
operation. Unfortunately since you will only have one gain value
available it will be necessary to use the lowest value needed (for
example Idleup 2). When using this method of controlling the
gain, one direction of the switch will be AVCS mode and the other
direction of the switch will be Normal mode. Always ensure the gyro
switch is set to the desired mode before fl ying. Do not accidentally
change the gyro switch in fl ight.
