24 SPEKTRUM DX8 • RADIO INSTRUCTION MANUAL
To Select Switch
Rotate the roller to highlight Sw (switch) then press to access the switch options.
Select the desired switch to change the dual rate for that channel or inhibit then
press the roller to make it active.
Note:
You can assign multiple channels to a single switch to affect the
dual and exponential rates of all.
To Select Switch Position to Adjust
Note Pos: Pos 0 in the center of the screen. Move the switch displayed at the
bottom of the screen to one of three positions from 0,1,2. When you make D/R or
Expo adjustments, values are assigned and automatically active when the switch
is in that position (Pos 0, 1or 2).
To Select D/R and Expo values
Confirm that the desired channel and switch position are selected. Rotate
the roller to highlight the D/R or Expo value then press to access. When the
corresponding channel’s control stick is centered both values are highlighted. If
you move the control stick to its endpoint, only one value will be highlighted.
This allows the D/R or Expo value in that direction only to change. With the
desired value selected, rotate the roller to select.
DIFFERENTIAL
The Differential function provides precise adjustments of up/down aileron travel
of each aileron (or elevon if Delta wing is activated). Typically, you can use
Aileron differential to reduce unwanted yaw characteristics. In aerobatic airplanes
adjusting differential provides an axial roll (minimum displacement of yaw
during a roll). You can program up to three Differential values and assign them
to a switch. Note that po and negative – differential is available; however,
normally more up aileron travel is required than down aileron.
Note: The Differential function is only available if Dual Aileron, Flaperon,
2 ailerons 1 flap, 2 ailerons 2 flaps or Elevon is selected in Wing Type
(see page 13) and each aileron servo is controlled by its own channel.
To Access the Differential Screen
With the transmitter on and the main or telemetry screen displayed, press the
roller. The Function list displays.
Rotate the roller to highlight Differential then press.
Differential defaults to Inhibit. Press the roller to highlight Inhibit then select one
of the following switch positions:
Inhibit - Off
On - Always on
Gear - Gear Switch
Flap - Flap switch
Ail D/R - Aileron Dual rate switch
Ele D/R - Elevator Dual rate switch
Rud D/R - Rudder dual rate switch
F Mode - Flight Mode switch
AUX 2 - Aux 2 switch
Mix - Mix switch
Press the roller to accept the desired switch. The differential adjustment screen
displays.
Highlight the desired differential position/value and press the roller to access.
Rotate the roller to change the value then press the roller. Repeat for all switch
positions desired.
Positive differential values provide more up than down aileron travel. Negative
differential values provide more down than up travel. The differential values
screen also allows you to select/change switch positions. Use the roller to
highlight SW then rotate to change to the desired switch position or inhibit the
function.
