designated for throttle function) and the other
side into the KOSMIK’s jack, that is marked as
Master
. Then switch on the receiver.
3.
Connect the motor cables to the motor.
4.
Connect the main battery to the KOSMIK.
5.
Mode-LED (LED 1) flashes green. You will hear
a ascending triad of sounds, monitoring the
activation. Ongoing you will hear single tones
for the recognized number of cells (see
4.1.7).6. Press the button (marked PRESS) on
the ESC (see 5 / sketch - No. 7), you will hear
a descending triad of sounds and the mode-
LED flashes in red.
6.
KOSMIK starts monitoring the modes, for each
mode there is the equal number of single
beeps, the mode-LED (LED 1) flashes in
correspondence with the beep number in
green.
7.
After 3 single beeps mode 3 is reached, slide
the gas channel to full throttle position (100%).
8.
The red LED changes to green and the ESC
confirms first the throttle position with an
ascending triad of sounds, then the mode with
3 single beeps.
Before disconnecting the battery from the
ESC it is essential to await the confirmation
(step 8), otherwise the KOSMIK realizes a
interrupted programming, blocks and
shows constant green light!

7.4 Mode 4 -
Helicopter mode
KOSMIK RPM pre selection
...
KOSMIK downward
KOSMIK upward
bail out
-
The heli mode operates with real RPM control
(governor). The motor RPM speed is kept
constant as long as the performance of the
battery and motor are sufficient for it. The ESC
stores all parameters of the program, such as the
ratio of selected RPM and the rotor’s speed at
every battery change. Activating the "Governor
Store," function via PROGDISC the KOSMIK
reads all parameters only once. During the first
start-up, these parameters are then permanently
stored
In mode 4 the ESC reads all parameters (such as
the ratio between selected RPM in the transmitter
and active rotor-RPM ) only once. The parameters
remains stored, beginning with the first start of the
motor.
Using different batteries with equal number of
cells leads to steady RPM even when changing
the battery.
Different cell numbers of the battery pack cannot
be compensated yet.
Therefore in mode 4 with governor store activated
it is not permitted e.g. to program with an 10S
battery and operating the same RPM with an 12S
battery afterwards.
When changing the set-up (motor, trans-
mission, rotor blades etc.) mode 4 must be
reprogrammed at each time !
Autorotation (bail out) is an integral part of mode
4. It cannot be selectively programmed with or
without AR.
Under voltage slow down (deep discharge
protection) is active, therefore the motor’s RPM
is turned down, when the adjusted battery
discharge voltage is reached (see 3.4). Smooth
start is at 12 seconds on default, but can adjusted
with the PROGDISC form 8 up to 60 seconds.
Also the BEC voltage is adjustable via PROG-
DISC from 5V up to 8V in 0.1V steps (see 4.3).
Preparing the transmitter
With a flight phase switch different RPM modes
are available on the throttle channel. Depending
on its position different RPM can be retrieved.
Example Set-up for Heli mode:
Start / motor off:
0%
Hover (Idle 1):
45%
Scenic flight (Idle 2):
60%
3D-flight
80%
Always a minimum of 20% reserve for the
ESC should be planed, otherwise a
sufficient RPM control is not ensured when
battery voltage decreases.
For the AR position (mode 4 only) a pre selection
of 25% is to be set in the transmitter.
By setting this pre selection the AR function is
prepared at all, no further settings are necessary
for using AR in mode 4.For further information of
transmitter programming, please see the
transmitter’s manual.
