Differential - Spektrum DX8 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.
With the transmitter on and the main or telemetry screen displayed, press the roller. The Function list
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.
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 positive + 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. 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.

Note: You can assign multiple channels to a single switch to affect the dual and
exponential rates of all.
To Select Switch Position to Adj ust
Note Pos: Pos 0 in the center of the screen. Move the switch displayed at the bottom of
impositions from 0,1,2. When you 7 make D/R or Expo adjustments, values are assigned and
automatically active when the switch is in that position (Pos 0, 1or 2).
To Access the Differential Screen
Rotate the roller to highlight Differential then press.

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 chanjj^to the desired switch position or inhibit the function.
