GRAUPNER mx-16 ifs - Program Description: Basic Settings - Model Helicopter (Continued); Main Rotor Direction and Swashplate Mixer Overview

51
Program description: basic settings – model helicopter
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 (HEIM
mechanics).
„3sv (2roll)“: 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 (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:
With the e
xception of the “1 servo” pre-set, the swash-
plate mixer ratios are set in the »swashp.mix« menu.

In the “rotor direction” line you enter the direction of
rotation of the main rotor using the rotary cylinder, after
pressing ENTER or the rotary cylinder:
“right”: the main rotor spins clockwise as viewed from
above.
“left”: the main rotor spins anti-clockwise as viewed
from above.
CLEAR switches to “left”.

The program requires this information in order to set up
the mixers to work in the correct “sense”; this applies to
the mixers which compensate for rotor torque and motor
power. You will fi nd these in the »heli mixer« menu:
