Rotate the roller to highlight Tail Curve then press.
Selecting a Flight Mode
Highlight the desired flight mode at the bottom of the screen then press to select.
Note that the selected flight mode will darken confirming the selection.
N= Normal
1= Stunt 1
2= Stunt 2
H= hold
Adjusting the Curve
Move the flight mode switch in the position you wish to adjust the curve to.
Highlight one of the five available Pitch curve values (Low, 25%, 50%,75%,
High). Press the roller to access that value.
Rotate the roller to adjust the selected point to the desired output position. Note
the position on the graph at the left of the screen.
Repeat this for all desired points.
To Activate the Expo Function
Rotate the roller to highlight EXPO then press to toggle between INH and ACT.
MIXING
The DX8 offers eight mixes in helicopter model type. You can program a cyclic-
to-throttle mix to advance the throttle when aileron, elevator and or rudder inputs
are given. This prevents rpm decay during cyclic and rudder inputs. A Swashplate
Mix mixes Aileron to Elevator and Elevator to Aileron to adjust swashplate timing.
Six programmable mixes allow the mixing of any channel to any other channel.
You can assign Mixes to activate in various flight modes as well as with the gear
switch. Programmable mixes include a trim offset function that adjusts the mix
crossover point and a trim include function that applies the master’s trim to the
slave channel.
To Access the Mixing Functions
With the transmitter on and the main or telemetry screen displayed, press the
roller. The Function list displays.
Rotate the roller to highlight Mixing then press. The Cyclic to throttle mix appears
on the screen.
Cyclic-to-Throttle Mix
Cyclic-to-throttle mix prevents rpm decay when aileron, elevator and or rudder
inputs are given. This mix advances the throttle position with cyclic or rudder
control to maintain rpm. At full throttle, programming prevents the throttle from
overdriving the servo.
Important: When using a governor, Cyclic to throttle mix is not recommended.
Assigning Cyclic Mix to a Flight Mode(s)
Rotate the roller to highlight the desired box at the bottom of the screen. Press the
roller to darken the box and activate Cyclic Mix in that flight mode position. You
can highlight more than one flight mode position. If all boxes are highlighted, the
C Mix function is always on. If no boxes are highlighted, the function is always off.
N= Normal
1= Stunt 1
2= Stunt 2
H= Hold
M=Mix
Adjusting Cyclic Mix Rates
Rotate the roller to highlight the desired rate then press. Rotate the roller to adjust
the value. The available po and negative - values reverse the direction of
the throttle mix.
Adjust the rates for all desired channels.
To verify that Cyclic mix is working properly and in the correct direction, place the
flight mode switch in one of the active positions. Move the programmed cyclic or
rudder channel noting the throttle position. The throttle position should increase.
If it decreases then the opposite value (positive vs. negative) is needed.
