The Sub-Trim function of the XR3i is an electronic trimming
feature that allows the neutral position of the servo on either
the steering, throttle or auxiliary 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 is
suggested that less than 30 points of Sub-Trim be used
during adjustment. If more than 30 points of Sub-Trim are
required, it is suggested that a mechanical linkage
adjustment be performed.
