The on-screen graph provides real-time feedback regarding how your D/R & EXP inputs affect
servo movement. Note that the y-axis of the graph moves as you manipulate the relevant
control stick for the current function being edited.

9. Scroll to highlight the “EXP” field and press the jog dial to
activate the menu.
10. By scrolling, you can highlight either the “L/U” (left/up),
the “R/D” (right/down) field, or both fields. If you want the
exponential movement to be the same for both directions of
servo travel (most common) highlight both fields and press the
jog dial.
11. Rotate the jog dial to increase (clockwise) or decrease
(counter-clockwise) the desired exponential value in high-rate
mode. This value is applicable for control inputs from neutral
to full left (AILE, RUDD) or full up (ELEV). Press the jog dial to
confirm your input.
12. Press the back button the return to the D/R & EXP menu.
13. Offest: Scroll to highlight the “OST” (Offset) field and press
the jog dial to activate the menu.
14. Offset allows you to set the neutral point of the servo to
different than the midpoint of its travel. This is helpful when you
require more servo travel in one direction than the other. Scroll
to select the desired amount of offset and press the jog dial to
enter your selection.
15. Switch Assignment: Scroll down to highlight the S/W field
and press the jog dial to activate the menu.

16. Scroll to select the switch you have chosen to control dual
rates for this function and press the jog dial to confirm your
selection. If you choose one of the 3-position switches, you can
set triple rates (high/mid/low).
17. Physically move the switch to the desired position for low-rates or mid rates and repeat steps 5-16 to
input the desired throws and exponential values for the selected function.
18. Repeat steps 4-17 for each control function.
19. Press the back button to return to the model menu.
The final settings in the D/R & EXP menu should reflect the model aircraft manufacturer’s
suggested control surface deflections for each function. Some manufacturers also provide
suggested exponential values.

The End Point Adjustment (EPA) feature allows you to fine tune the maximum servo movement for every
channel. This capability is very useful when dealing with models that require small control movements or
in cases where binding/damage could occur from excessive control movement.
End Point Adjustment
1. From the model menu, scroll to highlight “EPA” and press the
jog dial once to enter the EPA menu.
2. Scroll to the channel to be adjusted and press the jog dial to
activate the EPA sub-menu.
3. Scroll to highlight the left “LIMIT” field and press the jog dial to
activate the menu. This field defines the maximum servo travel
that can be set in the “left/up” direction. The value shown is a
percentage of standard servo travel (the default limit is 150%).
4. Rotate the jog dial to increase (clockwise) or decrease
(counter-clockwise) the desired “left/up” servo limit. Press the jog
dial to confirm your input.
If you are using multiple flight modes, you must define D/R and EXP values for each flight mode.
The top field of the D/R & EXP menu allows you to select the desired flight mode. Alternately,
you may select the desired flight mode using the assigned F.Cond switch.
