MULTIROTOR. Most ordinary MULTIROTOR do well at about 2 to 10 units. Generally
larger trim steps are for models with large control throws or for first flights to ensure
sufficient trim to properly correct the model. Smaller trim steps are later used to allow
very fine adjustments in flight.
HELI models only: OFFSET is available in the idle ups. If OFFSET is inhibited, adjustment of the
TRIM LEVERS will adjust the trims for all flight conditions. If OFFSET is active, then moving the
trims within any one condition will affect only that condition.

2.3.5 SUB TRIM
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. Otherwise, when the SUB-TRIM is of large
values, 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-TRIM (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 SUB-TRIM to make fine corrections.
