The mc-22s includes several programs for control-
ling the swashplate, differing in the number of ser-
vos which are used to provide collective pitch control.
Hold the rotary control pressed in initially to select the
“Swashplate type” line, then press the rotary control
briefl y to set the number of servos in the inverse fi eld.
The remainder of the parameters in lines 2 to 4 are
set in the same way (details below).
The servos must be connected to the receiver outputs
in the sequence described on page 37.
Swashplate type
„1 Servo“:
The swashplate is tilted by one roll
/ pitch-axis servo. Collective pitch is
controlled by one separate servo.
„2 Servo“:
The swashplate is moved axially by
two roll servos to provide collective
pitch control; pitch-axis control is de-
coupled by a mechanical compensa-
ting rocker (HEIM mechanics).
„3Sv (2roll)“: 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 col-
lective pitch control all three servos
move the swashplate axially.
„3Sv (2p.ax)“: 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.
Pressing
CLEAR
resets the swashplate type to “1
Servo”. The swashplate mixer ratios are set in the
»
Helicopter mixers
« menu, as is swashplate rotati-
on.
Note:
If none of the swashplate mixers is correct for your
model, you can adjust one of them to suit your own
swashplate type in the »
Helicopter mixer
« menu un-
der “Swashplate rotation”.
Swashplate type: 4 servos (90°)
