The AT9 has digital trims which are different from conventional mechanical trim sliders. Each TRIM
LEVER is actually a two-direction switch. Each time the TRIM LEVER is pressed, the trim is changed a
selected amount. When you hold the TRIM LEVER, the trim speed will increase. The current trim position is
graphically displayed on the start up screen. The TRIM submenu includes two functions that are used to
manage the trim options.
（
1
）
Trim reset (RESET): Electronically centers the trims to their default values. Note that the
SUB-TRIM settings and the trim STEP rate are not reset by this command.
（
2
）
Trim step (STEP): changes the rate at which the trim moves when the TRIM LEVER is activated.
It may be set from 1 to 40 units, depending on the characteristics of the aircraft. Most ordinary
aircraft 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.
