SUB-TRIM
: makes small changes or corrections to the neutral position of each servo. Range is -120 to +120, with 0 setting,
the default, being no
SUB-TRIM
.
We recommend that you center the digital trims before making
SUB-TRIM
changes, and that you try to keep all of the
SUB-TRIM
values as small as
possible. Larger
SUB-TRIM
values affect the servo's range of travel is restricted
on one side.
The recommended procedure is as follows:
• measure and record the desired surface position;
• zero out both the trims (
TRIM RESET
menu) and the
SUB-TRIMs
(this menu);
• mount servo arms and linkages so that the control surface’s neutral is as correct as possible; and
• use a small amount of

The servo submenu includes two features:
• real-time bar-graph display to demonstrate exactly what commands the
transmitter is sending to the servos. (This can be particularly handy in setting
up models with complicated mixing functions, because the results of each
stick, lever, knob, switch input and delay circuit may be immediately seen.)
