Tip:
If you test all servo reversing options and the control surfaces
do not move in the correct direction, change the Elevon wing type
in the System Setup list from Elevon-A to Elevon-B.
Flap System
The Flap System menu option enables flap programming as well
as elevator mixing. You must select a flap-enabled wing type in
Aircraft Type or the Flap System menu does not appear.
To activate the Flap System:
1. Access the System Setup list and select Aircraft Type.
2. Select a flap-enabled wing type and exit the System Setup list.
3. Access the Function List from the Main Screen and select
Flap System.
4. Select Inhibit and scroll to the switch or lever you wish to use to
control the flap channel.
5. Assign the Flap travel values and any desired Elevator mixing.
6. Select a Flap speed, if desired. Norm (default) does not have a
delay. Flap speed options range from 0.1s to 30 seconds.
ACRO Mixing
Rudder to Aileron/Elevator
Rudder to Aileron/Elevator mixing corrects coupling in knife edge
flight.
• Add Elevator mixing if the aircraft pitches toward the landing
gear or canopy.
• Add Aileron mixing if the aircraft rolls in knife edge flight.
• 1/2% mixing values are available for precision adjustment
of knife edge mixing values below 10% values.
Aileron to Rudder
Use Aileron to Rudder mixing to overcome adverse yaw character-
istics with certain types of aircraft (such as high-wing aircraft).
Elevator to Flap
Elevator to Flap mixing enables Flap movement when the Elevator
stick moves. Use Elevator to Flap mixing to add the spoileron func-
tion to 3D aerobatic aircraft. This mix is available when a flap or
dual aileron wing type is selected.
