SERVO SET
Enter this function to adjust any channel’s reversing, travel limits, or sub-trim settings. Press or to
select the desired function to adjust and press ENTER.
Reverse: Sets the rotational direction for a channel’s output relative to the movement of the control stick.
Move the cursor to the channel to adjust. Set to “NOR” normal or “REV” reverse. Adjust all reversing
settings before making any other settings or adjustments in the programming.
Travel limits: Sets the maximum travel limits for each channel. Limits can be set for each side of
center. If two channels are mixed, adjusting the travel limits of each individual channel may be necessary
to adjust the travel limits for the entire mix. Move the cursor to the channel to adjust. Defl ect the control
stick for that channel to one side and notice the cursor on-screen will move accordingly. Set the percent
for that direction of travel as needed. Move the stick to the opposite direction and repeat. Repeat for
all channels as needed.
Sub-trim: Finely adjusts a channel’s center position. Be aware that extreme adjustments of sub-trim
could possibly result in servo binding if the servo’s output arm moves too far in the model. This is
available for all channels.
DUAL-RATES, EXPONENTIAL
For setting dual-rates and/or exponential travel for the aileron, elevator, and rudder channels. Dual-rates
allows a channel’s maximum travel limits to be switched between two limits. Exponential changes the rate
at which a servo rotates per degree of control stick defl ection. The rate of servo movement is non-linear in
relation to the movement of the stick. The higher the exponential percentage, the more the servo will rotate
as the stick is moved away from center position.
To select the desired channel to adjust, press ENTER, then or . Press ENTER when fi nished.
To assign a different switch to change the dual-rate / exponential setting, move the cursor to the CTRL line
and press ENTER. Select the switch that will control this function as explained on page 12. Press ESC
when fi nished.
Different dual rate and exponential settings can be set for each position of the switch. Highlight the dual-
rate percentage and move the assigned switch to the position that will allow for the furthest servo travel.
Adjust this percentage to the widest travel distance as needed for this channel. Note that the slope of the
diagonal line in the graph changes as the percent is adjusted. Defl ect the control switch to the opposite
position, and adjust the percentage to the lowest travel distance needed. The diagonal line on-screen will
now show the slope for the low dual-rate setting. A low rate can allow for better control of the model while
on the ground, at low altitudes, or while performing certain maneuvers. A high rate can allow for optimum
control of the aircraft in mid-fl ight.
To set an exponential value, move the cursor to the EXPO line and repeat the steps explained above to set
a different value for each position of the control switch. This function can be handy for optimum control of
the model - especially around center-stick position, and when performing stunts or aerobatic maneuvers.
Moving the control stick for the channel shown on-screen will change the position of the vertical line in the
graph. The point where the vertical line intersects the diagonal line is shown at the bottom-left on the screen.
The “x” (horizontal) coordinate is on the left, and “y” (vertical) coordinate is on the right.
Repeat the above steps for each the aileron, elevator, and rudder channels as desired.
