Dual Elevator Servos (with a rudder)
(
AILEVATOR
) (
ACRO
): Many models use two elevator servos, plugged in separate
receiver channels. (Flying wings without a separate aileron control use
ELEVON
. V-shaped tail models use
V-TAIL
, p. 51.
Benefits:
• Ability to adjust each servo's center and end points for perfectly matched travel.
• Ease of assembly, not requiring torque rods for a single servo to drive 2 surfaces.
• Elevators acting also as ailerons for extreme stunt flying or more realistic jet
flying (optional).
• Redundancy, for example in case of a servo failure or mid-air collision.
Adjustability:
v
Direction of each servo 's travel may be reversed in
REVERSE
or the set percentages may be reversed here.
v
Elevator travels independently adjustable (both directions and percent).
v
Optional action as ailerons (defaults to
50%
response). This response
cannot
be activated/deactivated in flight.
Setting
AIL3
and
4
to
0
disables this feature. Note: if you want this, but on/off with a switch, set
AIL3
and
4
to
0
here, and use
2 mixes –
AIL-to-ELEV
and
AIL-to-AUX2
(assign a switch) – to get aileron action from the elevator servos when the assigned
switch is on.
The
AILEVATOR
mixing function uses one servo on each of the two elevators,
and
combines the elevator function with the
aileron function (unless aileron travel is set to
0
). For aileron effect, the elevators are raised and lowered opposite of one
another in conjunction with the ailerons.
Once
AILEVATOR
is activated, unless you zero out the aileron figures (see below), any time you move your ailerons or any
programming moves your ailerons (ie.
RUDDER-AILERON
mixing), the radio automatically commands both elevator servos
to also operate as ailerons. To deactivate this action, simply set the 2 aileron travel settings to
0
in the
AILEVATOR
function.
This way the elevators will work
only
as elevators.
If using the elevators as ailerons as well, be sure to move the elevator/aileron stick while checking the servo motions. If a
large amount of travel is specified, when the sticks are moved at the same time, the controls may bind.)

Activate twin elevator servos.
Deactivate the elevator-acting-as-
ailerons portion of this function.
Note: Depending upon your model's
geometry, you may need to reverse one
servo or set a negative percentage here.
Where next?
Open the
AILEVATOR
function.
Activate the function.
Optional: adjust up/down travel
when operating as ailerons. (Ex:
0
.)
Optional: adjust total elevator travel
of each servo. (Ex: right servo
elevator travel to
98%
, left to
96%
.)
