The Sub-Trim function of the DX3 is an electronic trimming feature that allows the neutral
position of the servo on the steering, throttle or third channel (optional) to be moved, while
allowing the electronic trim lever for that channel to remain in the center position. This
feature is very useful as it allows the servo arm/wheel position to be moved to help with
control linkage installation, eliminating the need to make mechanical linkage adjustments.
Although the Sub-Trim function is a very useful feature, it is suggested that only
small amounts of sub-trim be used so that no unwanted, non-equal servo travel is
created. It’s suggested that less than 30 points of sub-trim be used during adjustment.
If more than 30 points of sub-trim are required, it’s suggested that a mechanical linkage
adjustment be performed.
