servo Sub-trim
The Sub-Trim function corrects the neutral trim setting for steering and throttle, making it possible to center the trim switches
(Trm 1, Trm 2, and Trm 3) while ensuring the steering and throttle servo horns remain centered. When adjusting linkages, Sub-Trim
allows you to x an accurate center position. It's not unusual that when you center a servo and install the servo horn, the servo
horn is not perfectly centered. Sub-trim allows you to center the servo horn perfectly, without altering the servo End-Point travel.
The Sub-Trim function can also be used for Brake Sub-Trim when using the transmitter in 4CH Mode. In this case, channels 3
and 4 can be set independently.

2) Attach your servo's servo horn (or servo saver horn) to your servo in the position that is closest
to neutral (as close to centered as possible).
1) Before adjusting your model's linkages, be sure to set the three trim switches (Trm 1,Trm 2, and Trm 3) to the center positions
(0) as displayed in the Information Window.
SUB-T ST setting range is 100L to 100R. The default setting is 0.

3) Press the Function key to highlight the SUB-T menu. The cursor will
default to [ST] in the Programming Window.
4) Press the INC/+ and DEC/- keys to adjust the Sub-Trim value to center
the Steering servo arm.
Install servo horn centered
as close as possible.
5) Adjust the remaining Sub-Trim values using the same techniques.
The Steering and Throttle Sub-Trim functions utilize Parallel Trim Technology. This allows you to
adjust the Sub-Trim amount to center the servo horn and still maintain full servo travel (up to 150%)
in each direction.
