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.
