Special case (throttle curve OFF)
Electric helicopter, e.g. with brushless motor and speed
controller in regulator (governor) mode.
In this case there is no need to set up a throttle curve in
the transmitter. The speed controller, when set to regu-
lator mode, provides a constant system rotational
speed. All it requires is a fixed value for the required sys-
tem speed in each flight phase. The throttle curve can
be switched off in the menu Memory / Properties

automatically have the same value (= fixed value), re-
gardless of the point being adjusted.
Throttle curve AUTOROT (auto-rotation)
The fourth flight phase with model helicopters is auto-
rotation (AUTOROT = emergency landing after motor
failure). This always has highest priority of all flight
phases. This means: if you operate the "A-ROT" switch (=
I), the transmitter switches to the auto-rotation flight
phase regardless of the position of the flight phase
switch "F-PH 1-3" (= J). The throttle setting for auto-
rotation is not a curve, but a fixed value. This permits a
fixed throttle setting (e.g. reliable idle with glow motors
/ motor OFF with electric motors). The auto-rotation
flight phase is primarily used for practising auto-
rotation landings.
Points P1 ... P5 cannot be set separately. Changing one
value forces a change to all points. The fixed auto-
rotation throttle value is reduced or increased. Example:
Note:
It is only ever possible to display the throttle curve for
the active flight phase. If you wish to make changes to a
throttle curve, ensure that you first set the desired flight
phase.

14.12. Parameter: Thr. Min.
(idle, throttle limiter)
The parameter Min. determines the idle speed of the
power system when the throttle limiter is set to mini-
mum or idle (
13.3.4. Setup / Control / Throttle limit
min). In glow-powered models this is the speed re-
quired for starting the motor and a safe idle (approx.
20%). For electric-powered models this is set to -% =
motor OFF. This parameter takes effect in all flight
phases, and can be adjusted if required using the idle
trim (trim buttons for the collective pitch stick) ( ).
The horizontal dotted line in the graph shows the posi-
tion of the throttle limiter in all flight phases. The throt-
tle limiter limits the throttle setting, i.e. it never permits
a higher throttle value under any circumstances than is
set for the throttle limiter.
TIP:
To set the idle (Min. parameter) move the throttle lim-
iter to the idle setting. The change in idle Min. can then
be seen directly from the horizontal dotted line for the
throttle limiter.
