Establishing helicopter model type

This "Model type" menu is used to establish the type 
of model to be programmed. This also activates 
all characteristic mixers, coupling functions, etc. 
in preparation for subsequent programming of the 
specifi ed model type.

Briefl y tap the center 

 key of the right touch pad:

Control of the swashplate will require an appropriate 
program variant which corresponds to the number of 
servos operating pitch control.
In the meantime this selection is also infl uenced 
by the type of control exercised on swashplate 
servos. Since Flybar systems generally do not 
require transmitter-side swashplate mixers, when 
such a system is in use, "1 Servo" is generally to be 
selected as the swashplate type, regardless of the 
actual number of swashplate servos present. In this 
context, be sure the Flybar system complies with 
the included adjustment instructions as otherwise 
there is a risk the helicopter will not fl y.
After selecting the »Swashplate type« line with the 
cd selection keys of the left or right touch pad, the 
entry fi eld will be framed.

Briefl y tap the center

The current setting for number of pitch servos will be 
displayed in inverse video. Now choose the variant 
needed with the selection keys of the right touch pad. 
"1 Servo": 

A Flybar system is in use or the 
swashplate is tipped with one servo 
each for roll and pitch-axis. Pitch 
control will be affected by one
separate servo.

 

(Since helicopter models, like Flybar 
systems, which are operated with only 
1 pitch servo, neither need any of the 
three swashplate servos for pitch, 
pitch-axis and roll NOR the transmitter's 
mixer functions for pitch, pitch-axis and 
roll, the »Swashplate mixer« menu 
option will be suppressed in the Multi-
function menu.)

"2 Servo": 

Two roll servos will displace the 
swashplate axially to affect pitch 
control; nick control will be decoupled 
by a mechanical compensation rocker.

"3Sv(2Roll)": 

Symmetric three-point control of 
the swashplate with three, radially 
offset articulation points, each offset 
by 120 °, connected to one pitch-
axis servo (front or rear) and two 
roll servos (left and right). All three 
servos push the swashplate axially to 
affect pitch control.

"3Sv (140°)": 

Asymmetrical three-point control of 
the swashplate is affected at three 
articulation points connected to one 
nick servo (rear) and two roll servos 
(front left and right). All three servos 
push the swashplate axially to affect 
pitch control.

"3Sv (2Nick)":  Symmetric three-point control as 

described above but radially offset 
by 90°, one lateral roll servo and two 
pitch-axis servos, front and rear.

"4Sv (90°)": 

Four-point swashplate control 
affected by two roll servos and two 
nick servos.

Simultaneous tap on the 

cd or ef keys of the 

right touch pad (CLEAR) will reset the option back to 
"1 Servo".
