the overall travel or
endpoints of the servo
arm movement.

wheel. When adjusting travel values assigned to a control stick:
a. Center the control stick to adjust both directions at the
same time.

the control stick in the desired direction while you are
adjusting the travel value.
2. Scroll left or right to adjust the travel value. Press the scroll
wheel to save the selection.
Sub-Trim

servo travel center point.
CAUTION Use only small sub-trim values or you may
cause damage to the servo.
Reverse

to reverse the channel
direction. For example, if

up but should move
down.
To reverse a channel direction:

wheel.
If you reverse the Throttle channel, a confi rmation screen appears.

reminding you to bind your transmitter and receiver.
CAUTION: Always rebind the transmitter and receiver
after reversing the Throttle channel. Failure to do so will
result in the throttle moving to full throttle if failsafe activates.
Always perform a control test after making adjustments to confi rm
the model responds properly.
CAUTION: After adjusting servos, always rebind the
transmitter and receiver to set the failsafe position.
Speed
The Speed menu
enables you to show 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.
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.
Balance
Balance is available on
all channels to fi ne-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.
