Press briefl y on the center SET button in the right touch
pad. The current setting for number of pitch servos will
be displayed in inverse video. Now choose the variant
needed with the arrow keys of the right touch pad.
"1 Servo": The swashplate will be tipped with one
servo each for roll and nick. Pitch control
will be affected by
a separate servo.
(Since helicopter models operated
with only 1 pitch servo will be operated
WITHOUT the transmitter's mixer
functions for pitch, nick and roll, the
"Swashplate mixer" menu item in the
Multifunction menu will be hidden.)
"2 Servos": Two roll servos will displace the
swashplate axially to affect pitch control;
nick control will be decoupled by a
mechanical compensation rocker.
"3Sv (2Roll)": Symmetrical three-point control of
the swashplate is affected at three
articulation points, each radially offset
from the others by 120°, which are
connected to one nick servo (at the
front
or rear) and two roll servos (located
laterally at the left and right). All three
servos push the swashplate axially to
affect pitch control.
"3Sv (140)": Asymmetrical three-point control of
the swashplate is affected at three
articulation points connected to one nick
servo (rear) and two roll servos (front
left and right). All three servos push the
swashplate axially to affect pitch control.
"3Sv (2Nick)": Symmetrical three-point control as
described above but radially offset by
90°, one lateral roll servo and two nick
servos, front and rear.
"4Sv (90°)": Four-point swashplate control affected by
two roll servos and two nick servos.
Simultaneously pressing the

or

keys of the
right touch pad ( CLEAR ) will set the option back to
"1 Servo".
