The Trim Step function allows you to adjust how far the servo travels when the trim switch is moved. This allows you to change
the Trim function resolution to suit your preference. For example, in the default configuration, when you move the elevator trim
switch, the Trim percentage value changes in 6% increments. You can increase the resolution by decreasing the Trim Step value,
so that the servo travels less when you move the trim switch. This makes it possible to fine-tune the trim settings extremely
accurately. In addition, you could decrease the resolution by increasing the Trim Step value, so that the servo travels more when
you move the trim switch. This makes setting large amounts of trim faster, but the trim setting may not be as accurate.
You can choose to program Trim Step values separately for each of the five Flight Modes or you can use the same Trim Step
programming values across all five Flight Modes.
Programming F-MODE
Transmitter F-MODE refers to the Flight Mode that the transmitter is currently operating in. Programming F-MODE refers
to the Flight Mode that you would like to change the programming for.
Choosing the Flight Mode - Common or Separate
When set to COM (Common), the TRIM STEP settings will be the same regardless of which Flight Mode the transmitter is operating
in. You cannot program TRIM STEP settings separately for each Flight Mode. When set to SEP (Separate), you can program
different TRIM STEP settings separately for each Flight Mode.
1) Press the Navigation Pad 56 to highlight TRIM STEP, then press the
ENTER key to display the TRIM STEP menu. The cursor will default to
COMMON>COM.
2) Press the YES/+ or NO/- keys to choose either COM or SEP. If set to
COM, skip to the Setting the Trim Step Values section. If set to SEP,
see step 3 below.
3) Press the F-MODE key to choose the F-MODE number you would like to program the Trim Step function for. Choose from
N, 1, 2, 3, or 4. The F-MODE (N) display will change, indicating which Flight Mode you are programming the Trim Step
function for.
