Reverse; Sub Trim - Spektrum DX3S User Manual

reverse

The Reverse function (also known as servo reversing)
establishes the servo's direction relative to the channel's
input (e.g. 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.

sub TrIM

The Sub Trim function is normally used to correct 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.
