MIX
Flaperon, V-tail and Delta mixing are available for
specialty aircraft that require those functions. The
flaperon feature mixes flaps with ailerons so the
ailerons can be drooped for takeoffs and landings
while still functioning fully as ailerons. V-tail mixing
combines rudder and elevator for V-tail operations.
The Delta wing function allows the aileron to also act
as the elevator, while retaining independent use of
both functions. The Delta wing function allows the
ailerons to also act as the elevator, while retaining
independent use of both functions.
Flaperon Setup
When using flaperon mixing, two servos (one for
each aileron) must be used. Connect the left aileron
servo to channel #5 (Gear) and the right aileron servo
to channel #2 (Aile) in the receiver. Individual
functions (e.g., servo reversing, sub-trims, etc.) are
still available for each of the channels. Use sub-trims
for individual neutral adjustment.
V-Tail
V-Tail mixing requires two servos. Connect the left
tail servo to channel #3 (Elev) and the right tail servo
to channel #4 (Rudd) in the receiver. Individual
functions (e.g., servo reversing, sub-trims, etc.) are
available for each servo. Use sub-trims for individual
neutral adjustments described in Section 7.2. V-Tail
elevator travel is adjusted by elevator and rudder
travel adjust.
Delta Wing Mixing
Delta, or elevon mixing as it is commonly known, is
the final wing mixing selection in your XF421EX. This
style of aircraft also employs two wing servos.
However, in essence, there is not an elevator present.
Instead, at an elevator stick input, the two wing
servos function in conjunction with one another in
the same direction to create an up/down movement
of the aircraft. Also, when an aileron control is given,
the two wing servos move in opposite directions to
function as ailerons as well.
