Servo Setup; Function List - Spektrum DX18 Manuel D'utilisation

FUNCTION LIST

Servo Setup

Choices in this menu support fine-tuning the servo operation in
your aircraft.
Servo Setup supports travel adjustment, Sub-Trim, and servo
reversing. Speed, Absolute Travel and Balance are additional
features that increase fine control and management of servo
operation through the transmitter.
Servo Setup screens feature a servo monitor that shows a visual
reference for adjustments.
Travel Adjust
Travel Adjust sets the overall travel or endpoints of the servo. You
can use Travel Adjust to:
• Prevent overthrowing a control surface or blocked
movement
• Increase or decrease overall control surface throw
• Change flight performance of the model
Sub-Trim
Sub-Trim adjusts the center point for a servo's travel
CAUTION
Use only small sub-trim values so a servo's
maximum travel (in either direction) is NOT overdriven.
Reverse
Servo Reversing is used to reverse the direction of a servo, if
a control moves in the incorrect direction. When reversing the
Throttle channel, after pressing reverse, a screen will show
stating "Confirm Throttle Reverse. Are you sure? NO or YES" To
confirm, highlight YES and press the roller. A message appears,
reminding you to re-bind the system and set a new failsafe. If
you do not wish to reverse the throttle, highlight NO and press
the roller to prevent the throttle from reversing.
CAUTION:
Always test the model after making adjust-
ments to make sure the model responds to controls as
desired. Rebind the transmitter to the model and set the failsafe
after setting the Servo Setup.

Speed
This adjusts individual servo speed. The speed of movement for
each channel can be adjusted to slow the response. This is very
useful for scale applications where the speed of a scale detail
needs to be slowed.
Absolute (Abs.) Travel
Sets the maximum travel for a channel in any direction regard-
less of any other functions. Each direction can be set individually.
For example, mixing aileron to throttle causes an issue with
overdriving the throttle at full throttle when the mix adds in,
creating a bind. Abs. Travel can be set so that the servo will stop
at exactly full throttle, no matter what.
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 sync multiple servos (dual servo wing) so the
servos don't bind in all positions.
This can also be used to level swashplates for helis. All chan-
nels are available in the balance function and this feature
provides precision adjustment of all channels, as needed.
