Program description: base settings - model helicopter
buttons of the right-hand touch-key:
“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.
Simultaneously pressing the
cd
or
ef
buttons of the
right-hand touch-key (
CLEAR
) resets the swashplate
type to “1 servo”.

Cut off
As part of the auto-rotation set-up procedure of the
mx-16
HoTT transmitter’s Helicopter program there is
the option to defi ne a “motor OFF” position for the throt-
tle servo or speed controller for use in an emergency.
However, if you set an idle position in the “Throttle” line
instead of an emergency OFF position - for example, in
order to avoid having to re-start the engine after every
practice auto-rotation landing - then this option is not
available. In this case we recommend that you use the
“Motor stop” option described below as the emergency
OFF solution. Depending on the option (“forward / back”)
you have selected in the “Collective pitch minimum”
line, you can defi ne a “Motor OFF” position in this menu
line which can be called up by operating a switch. The
