Elevator-to-flap mixing makes the flaps drop or rise whenever the elevator stick is
moved. It is most commonly used to make tighter "pylon" turns or squarer corners
in maneuvers. In most cases, the flaps droop (are lowered) when up elevator is
commanded.
Setting Elevator-to-Flap Mixing
Turn the ELE-FL function ON or OFF by pressing
the (+) key ("ON" or "OFF"displayed ). Turn off
(INH) the function with the (-) key.

V-tail mixing is used with V-tail aircraft so that both elevator and rudder functions are
combined for the two tail surfaces. Both elevator and rudder travel can be adjusted
independently on each surface. Because they share receiver outputs, Elevon and V-
Tail mixing cannot be activated simultaneously.
Setting up V-Tail mixing
1. Turn the V-TAIL function ON by pressing the
(+) key ("ON" displayed ). Turn off (INH) the
function with the (-) key.

Be sure to move the elevator and rudder sticks continually while checking the servo motions. If a large value of
travel is specified, when the rudder and elevator sticks are moved at the same time, the servo travel may be
large, and controls may bind or run out of travel.

and set the desired travel with
