Helicopter type

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.

Swashplate type
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
selection keys of the left or right touch pad, the
entry fi eld will be framed.

"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
1 Ser vo
articulation points connected to one
nick servo (rear) and two roll servos
no
(front left and right). All three servos
right
push the swashplate axially to affect
rear
pitch control.
SEL
"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
right touch pad (CLEAR) will reset the option back to
"1 Servo".
