SYSTEM SETUP
x-Plus Input Configuration
The X-Plus Input Configuration screen enables you to assign any
X-Plus channel to any transmitter input.
1. Select NEXT on the Channel Input Config screen to access the
X-Plus Input Config screen.
2. Scroll to the X-Plus channel you wish to change.
3. Press the scroll wheel once and scroll left or right to change
the X-Plus Input for that X-Plus channel.
CAUTION: Do NOT connect throttle or any primary con-
trol surface to the X-Plus Module. The X-Plus channels
are intended to be used for auxiliary functions only. X-Plus chan-
nels have a resolution of 512 and variable latency from 22ms to
about 88ms. When X-Plus is active, the first 10 channels default
to 22ms.
Trim Setup
Use the Trim Setup screen to change the size of the trim step
and the trim type.
Trim Step
Adjusting the trim step value determines how many "clicks" of
trim you input each time you press the trim button. Changing
the trim step value to 0 disables the trim for the channel.
To change the trim step value:
1. Scroll to the trim step channel you wish to change.
2. Select the trim step value and scroll left or right to change
the value.
3. Press the scroll wheel to save the selection.
Trim Type
The two Trim Type options are Common and F Mode.
Common trim type maintains the same trim values for all flight
modes.
F Mode trim type enables you to save trim values for individual
flight modes if you find, for example, the aircraft requires aileron
trim in Flight Mode 1 but not in Flight Mode 2.

gimbals.
