Balance
Balance is available on all channels to fine-tune the servo position
at up to 7 points. This is a precision curve mix that is normally
used to prevent binding when multiple servos are used on a single
control surface.
You can also use the Balance menu option to match throttle response
on twin engine aircraft or level the swashplate on a helicopter.
Channel Name
This page enables you to rename each channel to suit your setup.
To rename a Channel:
1. Press the scroll wheel to select the menu.
2. Scroll down to select the channel you want to rename.
3. When the channel is selected press the scroll wheel again to open
the sub page.
4. Enter a short name and a long name for the channel.
Absolute (Abs.) Travel
The Abs. Travel function limits the amount of travel on a channel.
Adjust the Abs. Travel value to prevent a servo from binding when
a mix is applied.
Speed
The Speed menu enables you to slow the response time on any
individual channel (such as retracts).
The Speed is adjustable in the following ranges:
• Nor (No Delay) – 0.9s in 0.1 second increments
• 1s – 2s in 0.2-second increments
• 2s – 8s in 1-second increments
To adjust the Speed:
1. Scroll to the channel you wish to adjust and press the scroll wheel.
2. Scroll left or right to adjust the speed and press the scroll
wheel to save the selection.
Multiple travel rates and exponential (expo) are available on the
aileron, elevator and rudder channels. Rates enable the pilot to
set up different amounts of control travel which can be selected
from a switch or flight mode. Exponential affects control response
sensitivity around center but has no affect on overall travel.
Positive exponential decreases the sensitivity around the center of
gimbal movement.
To adjust the Dual Rate and Exponential:
1. Scroll to the channel and press the scroll wheel once. Scroll
left or right to select the channel you wish to change and
press the scroll wheel again to save the selection.
2. Scroll to Switch and select the switch to activate D/R and Expo
for that channel.
3. Scroll to dual rate and press the scroll wheel. Scroll left or
right to change the value and press the scroll wheel again to
save the selection.
