is framed. Press the SET button: the current number of
collective pitch servos is highlighted on the screen. You
can now determine the required variant using the arrow
buttons of the right-hand four-way button:
“1 servo”: The swashplate is tilted by one roll servo
and one pitch-axis servo. Collective pitch
is controlled by one separate servo.
The Swashplate mixer menu point is
suppressed in the multi-function menu if
you select “1 servo” as the swashplate
type. This is because model helicopters
with only one collective pitch servo are
controlled WITHOUT transmitter mixers
for the swashplate functions collective
pitch, pitch-axis and roll.
“2 servo”: The swashplate is moved axially by two
roll servos for collective pitch control;
pitch-axis control is de-coupled by a
mechanical compensating rocker.
“3sv(2rol)”: A symmetrical three-point swashplate
linkage using three linkage points ar-
ranged equally at 120°, actuated by one
pitch-axis servo (front or rear) and two
roll servos (left and right). For collective
pitch control all three servos move the
swashplate axially.
“3sv(140)”: Asymmetrical three-point swashplate link-
age using three linkage points, connected
to one pitch servo (rear) and two roll
servos (front left and right). For collective
pitch control all three servos move the
swashplate axially.
“3sv(2nic)”: A symmetrical three-point linkage as
above, but rotated through 90°, i. e. one
roll servo on one side, and two pitch-axis
servos front and rear.
“4sv(90)”: Four-point swashplate linkage using two
roll and two pitch-axis servos.
Note re. “4Sv (90°):
As can be seen in the receiver assign-
ment on page 47, the second pitch-axis
servo is connected to output 5. For this
reason the “Gyro” option, which is
assigned to output 5 as standard for sys-
tems with 1 … 3 collective pitch servos,
is suppressed in the Helimix menu and
the line of the same name in the Trans-
mitter control settings menu.
Simultaneously pressing the cd or ef buttons of the
right-hand four-way button (CLEAR) resets the swash-
plate type to “1 servo”.
