OTF (ON THE FLY) TRIM FUNCTIONS
AUTO SWITCH SELECT
To easily select a switch in a function, such as a program mix,
roll with the scroll wheel to highlight the switch selection box, and
press the scroll wheel. The box around the switch should now
flash. Verify the switch selection is now displayed as desired. When
correct, press the scroll wheel to select this switch and complete
the switch selection.
KEYBOARD STYLE
There are three different styles of keyboard entry for the letters.
• SwiftBoard – Full keyboard with numbers on top (default)
• RapidBoard – Full Keyboard with number pad on right
As you scroll to the next line the selection will jump down to the
next line. Scrolling through the keyboard characters is normally
side to side. Holding the function key down while scrolling
changes the navigation direction to up and down.
A set of letters with accents appear when a vowel is
highlighted. Press and hold the function key and click the scroll
wheel to select an accented letter.
• Legacy – Original single line input, with scrolling through
individual characters
To activate the OTF feature for a given function:
1. Navigate to the desired function screen.
2. Select OTF to open the Configuration screen.
3. Select Inhibit to select a switch.
4. Select the desired trim switch to assign to the trimmer value.
Each trim button may only be assigned to a single function at a
time. If a trim button is already in use elsewhere, a warning dialog
appears asking to confirm the change to the new function.
5. Select the Min / Max values to assign a minimum and
maximum value for the trimmer. The minimum value is the
lowest value the trim button will adjust to. The maximum value
is the highest. Touch OK when the Min / Max values are set.
CAUTION: Never assign a minimum or maximum value
that could negate the travel of a control surface, such as
with dual rates. Setting a dual rate value of 0% will keep the
control surface from moving and could cause a loss of control of
the aircraft.
Many functions of the NX20 allow for making fine adjustment using available trim switches while flying your aircraft including:
• Dual Rate
• Exponential
• Programmable Mixes
• Pre-Configured Mixes
• Flap System
• Differential
• V-Tail Differential
• Camber Presets
• Camber System
