Wing Mixing Type Selection Wing Mixing Type Selection
There are two different wing mixing functions to select from:
V-tail mixing V-tail mixing
Intended for V-tail aircraft (such as a Beechcraft Bonanza), V -tail mixing allows the
ruddervators to operate both as rudders and elevators. V -tail mixing requires that
each ruddervator be operated by a separate servo.
To activate V-tail mixing: To activate V-tail mixing:
1. Connect the left ruddervator servo to channel 2 (elevator) in the receiver and
connect the right ruddervator servo to channel 4 (rudder) in the receiver.
2. Enter the programming mode. Access the ““WING WING”” screen with the MODE key.
3. Push the DATA INPUT lever upward or downward for about a half second to select the V-tail
mixing.
You cannot set ““V-tail V-tail”” mixing when ““Elevon Elevon”” mixing has already been set.
4. Once this mix has been activated, move the servos to their full extremes to make certain they are not overdriving the
controls. If necessary, adjust the linkages to achieve the correct control throws.
Elevon mixing Elevon mixing
Intended for tailless, “ flying wing ” models such as delta wings and flying wings,
elevon mixing mixes channel 1 (aileron) to channel 2 (elevator) allowing the
elevons to operate in unison (as elevators) or in opposition (as ailerons). This
function requires that each elevon be operated by a separate servo.
To activate elevon mixing: To activate elevon mixing:
1. Connect the servo in the right wing to channel 2 (elevator) in the receiver and connect the
servo in the left wing to channel 1 (aileron) in the receiver.
2. Enter the programming mode. Access the ““WING WING”” screen with the MODE key.
3. Push the DATA INPUT lever upward or downward for about a half second to select the
Elevon mixing.
You cannot set ““Elevon Elevon”” mixing when ““V-TL V-TL”” mixing has already been set.
4. Once this mix has been activated, move the servos to their full extremes to make certain they are not overdriving the
controls. If necessary, adjust the linkages to achieve the correct control throws.
*If necessary, use the Servo Reversing
function to achieve the correct direction of
servo throws.
*If necessary, use the Servo Reversing
function to achieve the correct direction of
servo throws.
