Swash
Pitch, Roll and Nick Mixer
This submenu option is not available for the model set-
ting 1SERVO NOR.
This function is used to fine tune the outputs of the
mixing. Three interdependent servo linkages arranged
around the swashplate share the workload of con-
trolling control roll, control pitch and collective pitch.
Swashplate mix numbers represent the % of servo
function movement and the +/- symbols indicate di-
rection the servo will move. For example, increasing a
servo output to +70% will increase the servo function
range and blade pitch while an output in one direc-
tion, while -70% will increase the servo function range
and blade pitch in the opposite direction.
To adjust these settings, from the main display press
the FUNCTION menu gear icon (blue “F”) to bring up
the FUNCTION submenu screen:

When setting up a model through the BASE submenu
Model Type, the number of servos needed for pitch
control is selected. Once this entry is made, the re-
quired mixers for the swashplate functions of roll, el-
evation and pitch axis are activated so that additional
mixers do not need to be defined.
If the model is controlled using a separate pitch ser-
vo, the Swash submenu is unnecessary since three
software program operates the swashplate servos
seperately for pitch, elevation and roll (i.e. without any
mixer) and the Swash submenu will not appear in the
FUNCTION menu if the 1SERVO NOR option is se-
lected during setup:

For all other swashplate linkages employing 2, 3 or 4
collective pitch servos, the mixer ratios and directions
are set up by default. In the following examples, the
swashplate type 3SERVO 140 was selected. The de-
fault preset is +61%:

Values can be varied from -100% to +100% as need-
ed.
To change the values, press to highlight the field of the
mixer to be changed. In the example below, the ROLL
needs to be increased to +67%:

Press the RES button to reset the changed value
back to the default.
If the swashplate control (pitch, roll and elevation)
does not respond to the control sticks properly, alter
the mixer directions (+/-) before correcting the servo
rotation direction.
Notice
Ensure that changed mixer values do not result in
the servos mechanically striking their end-stops.
To save and exit, press the BACK button at the top
left of the display to return to the previous menu.
