Swashplate type
You will require a particular program variant to suit the
number of servos which operate the collective pitch
function. Press the SELECT button.
The current number of collective pitch servos is highligh-
ted on the screen. You can now determine the required
variant using the right-hand rocker 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 me-
chanical compensating rocker (HEIM
mechanics).
„3sv (2roll)":
A symmetrical three-point swashplate lin-
kage using three linkage points arranged
equally at 120°, actuated by one pitch-
axis servo (front or rear) and two roll ser-
vos (left and right). For collective pitch
control all three servos move the swash-
plate axially.
„3Sv (2nick)": 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.
CLEAR resets the swashplate type to "1 servo".
Note:
The swashplate mixer ratios are set in the »Swashpla-
te mixers« menu.
