Once the KOSMIKs Heli mode has turned
down the RPM, no direct booting is
possible. Only after plugging a sufficiently
charged battery pack further operating is
released.
4.10 Helicopter mode
In Helicopter mode the RPM control is active. The
motor RPM speed is kept constant.
The
KOSMIK
can
compensate
for
load
fluctuations and a decrease of battery voltage, as
long as the performance of the battery and motor
are not exceeded. There is no need to use a
separate TX mixer to stabilize the rotor's RPM.
RPM control works only if the ESC is
installed in the helicopter. Operating under
no load (without 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
unless GOV STORE is selected. To start the
motor, slide the throttle stick to the previously
mentioned position (0° pitch). The KOSMIK ESC
will smoothly increase the motor RPM within the
preset time (see 3.3). As soon as the designated
RPM is reached, the KOSMIK switches over
automatically to RPM control mode.
The higher the adjusted percentage for the flight
mode is set in the transmitter (see 3.2), the higher
the regulated motor RPM. Choosing the motor off
position in your transmitter means the motor will
shut down. The motor off position should not be
used during the flight, as the KOSMIK will revert
to soft start (see 3.3).
An exception to this is the mode 4 with
autorotation mode activated. This will bypass the
soft start when switching back from AR mode to
normal operation mode.
4.11 Auto Rotation (Bail out)
Due to the auto rotation quick start function, the
motor is returning in a much shorter time to normal
RPM after an interrupted or unsuccessful
autorotation. As an abrupt return to regulated
head speed is probable when using AR, please
ensure your blades are not loose in the grips
before takeoff. In order to have the quickest
available spool up time without mechanical
overloading, the spool up time after bail out is
calculated automatically on the programmed
spool up time and differs between 2 -6 s.
The motor is switched off without delay, when
changing to the AR mode. The correct AR position
is already to be set in the transmitter to 25% for
Spektrum and 30% for Futaba. It must not be
programmed separately to the KOSMIK ESC (see
7.4). Switching to the AR position during an active
flight, the motor is switched off at once and the AR
function is activated.
When interrupting the active AR function with Idle
1, Idle 2, Idle x, the motor switches on again and
spools up to the adjusted RPM value in quick start
as described above.
When interrupting the active AR function and
switching off the motor, the KOSMIK ESC activates
the smooth start function for the next motor start.
5. Connecting the cables
WARNING: always use only the included
cable assemblies (motor and battery
cables). During installations the ESC must
always be switched off (no battery connec-
ted)!
Always use the included screws and washers to
make a tight fit when installing!
After installation isolate each connection properly
with the supplied heat shrink tubing against
accidental electrical short.
5.1 BEC cables
With the KOSMIK BEC, digital servos with high
performance can be used:
10 A continuous Current
30 A temporary max. Current
To provide full BEC power all KOSMIK ESCs
feature two BEC connectors which have to be
used when BEC current is more than 5 A.
• The „Master“ connector must be plugged to the
throttle channel.
• The „Slave“ connector can be plugged in to any
unused receiver channel.
5.2 Motor cables
Please ensure the motor cables are properly
attached with the included attachments. if you
wish to change the direction of the motor,
