Symmetric three-point control as described above
but radially offset by 90°, one lateral roll servo and
two pitch-axis servos, front and rear.
• "4Sv (90°)"

1
Four-point swashplate control affected by two roll
servos and two nick servos.
Simultaneous tap on the  or  keys of the right
four-way button (CLEAR) will reset the option back to
"1 Servo".
Note:
Except for the "1 Servo" choice, swashplate
mixer proportions must also be set in the
»Swashplate mixer« menu, page 216.
Swashplate linearization
After selecting the "Linear. swashpl." line with the 
selection keys of the left or right four-way button, the
entry field will be framed:
Heli type
Swashplate 3Sv(2rol)
Linear. swashpl.
Rotor direct
Pitch min.
The "yes" entry will prevent undesired side effects such
as pitch change due to a roll function or tension be-
tween swashplate servo rods.
This type of tension can arise when effected servos
strain for different displacement positions due to travel
which deviates from one another.
Linearizing will require a bit of familiarization on the
part of the pilot because, in order to linearize the entire
rotation travel of the servo arm, servo travel is reduced
in small control movements – similar to a pronounced
exponential setting.
Rotor direction
After selecting the "Rotor direction" line with the 
selection keys of the left or right four-way button, the
entry field will be framed:
Swashplate
Linear. swashpl.
Rotor direct
Pitch min.
After a tap on the centre
rection of rotation is entered in the "Rotor direction" line
with the selection keys of the right four-way button:
• "right"
The main rotor turns clockwise when viewed from
above.
• "left"
The main rotor turns counter-clockwise when
viewed from above.
A simultaneous tap on the  or  keys of the right
four-way button (CLEAR) will set the option to "right".
