MIXING
The DX8 offers eight mixes in airplane model type. There is an Elevator to Flap

mixing of any channel to any other channel. 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. You can assign Mixes to the
following switches or flight modes:
Inhibit - Off
On - Always on
Gear - Gear switch
Ail - Aileron dual rate switch
Ele - Elevator dual rate switch
Rud - Rudder dual rate switch
FM1 - Flight mode 1
FM2 - Flight mode 2
FM1, 2 - Flight mode 1 and 2
Mid - Flap switch mid position
Land - Flap switch land position
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. Note that the Elevator to Flap mix
appears on the screen if the appropriate wing type is selected.
AILERON TO RUDDER MIX
Use Aileron to Rudder mixing to overcome adverse yaw characteristics with
certain types of aircraft such as the J3 Cub and make coordinating turns easier.
To access Aileron to Rudder Mix
IIf you accessed the flap option in wing type in the system setup mode, the
elevator to flap mix will display. Rotate the roller to highlight ELE > FLP then
press. Now rotate the roller to select Ail > RUD and press. The aileron to rudder
Mix screen appears.
Assigning Aileron to Rudder Mix to a Switch
Rotate the roller to highlight Sw: at the bottom of the screen. Press the roller to
access the switch select function then select the desired switch to turn on/off the
aileron to rudder mix. If you select On, the mix will always be on.
Adjusting Aileron to Rudder Mix Rates
Rotate the roller to highlight the rate values then press. Note that both rates are
boxed. Moving the aileron stick right or left causes the right or left value only to
be highlighted so you can adjust the values individually. Move the aileron stick
in position to highlight the desired rates then rotate the roller to adjust the value.
Note that po and negative - values reverse the direction of the mix. Press
the roller to accept the rate.
Verify the aileron to rudder mix is working properly and in the correct direction by
placing the active switch in the active position and moving the aileron stick noting
the rudder position. If the rudder moves in the opposite direction than desired,
the opposite value (positive vs. negative value) is needed.
Note: the Elevator to Flap mix operates in the same fashion as alieron to
rudder mix.
PROGRAMMAbLE MIXES
Programmable mixes allow any channel to be mixed to any other channel or to
itself. Popular programmable mixes include rudder to steerable nose wheel, dual
rudder mix, dual elevator mix, rudder to aileron and rudder to elevator mix for
knife edge correction.
