The Reverse function (also know as servo reverse)
establishes the servo’s direction relative to the
channels input (i.e. a right steering input should
result in a right steering angle at the car). Reverse
is available on all three channels and is normally
the first function that is checked and adjusted
during programming.
The user name and model number and model name
are also displayed in this screen.

Sub Trim
≤
The Sub Trim function is normally used to correct for
minor angular inaccuracies that occur when placing
the servo horn on the servo. In many cases, the
servo horn is not exactly perpendicular to the servo
(or in the exact optimum desired position). Minor
sub trim values can be used to correct this offset
inaccuracy, however, it’s important to understand that
large sub trim values can limit the total throw of the
servo in that direction so small sub trim values only
are recommended.
The user name, model number and model name are
also displayed in this screen.
To aCCess The sub TrIM funCTIon:
In the List screen use the roller to highlight the Sub
Trim function.
