Gyro System
To activate the gyro function you need to use device select in the system menu
to assign a switch to the gyro function. The gyro system allows you to easily fit a
gyro to your aircraft. Gyros normally reserved for helicopters can now be easily
utilised using the PCM9X gyro function. Gyros help stabilise flight controls and are
particularly useful for elevator control on pitch sensitive aircraft. You can have 2
gyros in use, one activated by Aux 2 and another by Aux 3. The software also
allows you to dynamically change the gain in relation to a stick movement. For
example if you select Aileron under the stick item within the gyro menu you will be
able to see a second series of gyro gain values for the end of stick travel as well as
centre stick.
Aileron Differential
Aileron controls do not provide equal amounts of drag when they are operated.
The downwards-moving aileron always provides more drag than the upwards-
travelling aileron. This can result in adverse yaw because of the drag difference.
Aileron differential mixing reduces the throw of the downwards-moving aileron to
counteract this drag difference.
Aileron differential is only active for twin aileron servo installations when the
Flaperon or Delta options are selected in Wing Type. Each aileron control surface
must have its own servo with the right aileron servo plugged into the aileron
channel on the receiver and the left aileron servo plugged into the flap (AUX1)
channel on the receiver. If these are the wrong way round, the differential will
apply to the up going aileron!
0% gives you normal aileron control, 50% provides differential control whilst
100% gives split aileron control (e.g. no downward aileron movement). Again this
system can be set to activate at a set throttle position using the THRO STK
function.
Servo Speed
The servo speed function allows you to independently control the speed of the
servos in your aircraft. The servos can be slowed down to 15 seconds per 60
degrees of movement.
