The Reverse screen allows you to specify the direction of servo rotation for channels 1-8 of the active
model.
Servo Reverse
1. From the model menu, scroll to highlight “REVERSE” and press
the jog dial once to enter the reverse menu.
2. Scroll to the channel to be reversed and press the jog dial to
activate the selections:
NOR (default):
Normal rotation.
REV:
Reverse rotation.
3. Once you have chosen the desired direction, press the jog dial
to confirm your selection.
4. Press the back button to return to the model menu.
The Sub Trim menu is used to make very fine adjustments to the center point, or “neutral point” of a
servo. It is typically preferable to have the servo arm 90° to the pushrod at the neutral point. Use sub trim
settings to attain this orientation. Then, adjust the length of the pushrod to achieve the desired neutral
control surface position.
Sub Trim
1. From the model menu, scroll to highlight “SUB TRIM” and press
the jog dial once to enter the sub trim menu.
2. Scroll to the channel to be adjusted and press the jog dial to
activate the menu.
3. Rotate the jog dial clockwise or counter-clockwise to alter the
servo neutral point.
4. Once you have achieved the desired neutral point, press the
jog dial to confirm your change.
5. Press the back button to return to the model menu.
The Dual Rate (D/R) feature provides a method to define two different values of servo movement (“rates”)
on the same channel. You may want low control rates during takeoff and landing and higher rates when
performing aerobatics. One or more switches are assigned to allow the pilot to select high or low rates.
Exponential Rate (“EXP”) is a powerful function that is often used to make a twitchy model easier to
control. Negative exponential values typically make a model less sensitive to moderate control inputs,
yet you still have the same amount of overall control throw. Positive exponential values are generally
detrimental to a model’s controllability and should be avoided.
Dual Rates
Before entering the D/R & EXP menu, it is helpful to decide which switch or switches you want to
control dual rates, as well as the switch positions that will be used for high-rates and low-rates.
The same switch can be used to manage dual rates for one or more control functions.

Caution
1. From the model menu, scroll to highlight “D/R & EXP” and
press the jog dial once to enter the D/R & EXP menu.
2. Scroll to highlight the function field (RUDD, ELEV, etc) and
press the jog dial to activate the menu.
3. Rotate the jog dial to select the desired function and press the
jog dial to confirm your selection.
4. Locate the switch that you will use to control dual rates for this
function and move it to the desired position for high-rates.
5. Scroll to highlight the “D/R” field and press the jog dial to
activate the D/R sub-menu.
6. By scrolling, you can highlight either the “L/U” (left/up), the
“R/D” (right/down) field, or both fields. If you want the dual
rates to be the same for both directions of servo travel (most
common) highlight both fields and press the jog dial.
7. Rotate the jog dial to increase (clockwise) or decrease
(counter-clockwise) the desired travel for the servo(s) in high-
rate mode. The value is a percentage of the available servo throw
from neutral to full left (AILE, RUDD) or full up (ELEV). Press the
jog dial to confirm your input.
8. Press the back button the return to the D/R & EXP menu.
