4.9 Helicopter Mode

In helicopter mode, motor RPM control (Governor)
is active. The motor RPM speed is kept constant in
relation to flat line throttle curve programmed in
your transmitter. RPM control can compensate for
load fluctuations and decreasing battery voltage,
as long as the battery and motor are capable of the
requested power demands. RPM control works
only if the ESC is installed in the helicopter.
!
Operating your helicopter without main
blades may result in a jerking ESC.
It is recommended to set 0° pitch at spool up to
ensure relatively constant RPM during each flight.
To start the motor, disengage throttle-hold while in
any flight mode with a straight line throttle curve.
The KOLIBRI ESC will smoothly increase the motor
RPM within your preselected spool-up time (see
3.3 for adjustment of spool-up).
Once the designated RPM is achieved, the
KOLIBRI switches over automatically to RPM
control mode (Governor). You may adjust the flat-
line throttle curve in each of your flight modes to
provide you with different head speeds for each
mode.
If you select Throttle Hold at any point in flight,
please note that soft start will engage unless you
are in Mode 4 and have Autorotation enabled. If
Autorotation Bailout is enabled, initial spool up
speed is bypassed when disengaging throttle hold
and reengaging a standard flight mode (see 3.3 for

Autorotation Bail out).

4.10 Autorotation (Bail out)
Due to the autorotation quick-start function, motor
RPM returns to normal much faster. This provides
the opportunity to bail out of an unsuccessful or
interrupted Autorotation. In order to have the
quickest available
mechanical overloading, the spool up time after bail
out is calculated on the programmed spool up time
and differs between 2 - 6 s.
In order to enable Autorotation Mode (Bail out), you
must set the throttle-hold value to 25% in your
transmitter (see 7.4). Switching to the AR (throttle
hold) position during an active flight, the motor is
switched off at once and the AR function (bail out)
is activated.
