Control
An ARF-MikroKopter is easy to fly. But it takes practice and time to be able to control the Kopter safely. The pilot must
also be able to fly the Kopter in any situation without aids such as the GPS-System.
The Kopter is controlled by a C-transmitter. The Throttle, Yaw,
oll and Nick functions can be controlled by the sticks.
•Throttle
◦Controls the speed of the motors (up/down)
•Yaw
◦Turns the Kopter around
•Nick
◦Flies forward or back
•Roll
◦Flies left or right
(Example: Mode2)
Ideally the A F-MikroKopter can stay on position with no wind.
Info: Please leave the trim of the transmitter in middle position (off)
Via the switches, buttons and potentiometer of the transmitter further functions
like e.g. the automatic hold of the actual position (PositionHold), an automatic
back-flight to the start point (ComingHome) or non-directional flying (CareFree)
can be used.
For this purpose the mounted GPS-System and the compass-sensor is used. The
GPS system consists of the MK-GPS and NaviCtrl. The compass sensor is
installed on the NaviCtrl.
The functions are further described in „Functions / Flight modes“.
Before each flight
Check the Kopter always for:
•Damage to the frame, cables, motors, propellers and electronics
•Tightness of the rigger, motors and propellers
•Functions of the motors
•Tightness of all screws (Motors, igger etc.)
•Loaded and not damaged batteries (ARF-MikroKopter and transmitter)
The order of switching on / off the ARF-MikroKopter and the transmitter:
Switch on (before the flight):
1. All switches on the transmitter put into the default „OFF“.
2. Switch on the C-Control (if necessary choose the right model memory).
3. Bring the trim of the control-sticks into the middle position.
4. Connect the ARF-MikroKopter to the battery (LiPo).
Switch off (after the flight):
1. Switch off the motors.
2. Disconnect battery (LiPo) from the ARF-MikroKopter.
3. Switch off the transmitter.
(See also „Maintenance“ Pg. 48)

Flight simulator
To get familiar with the controls we recommend practicing with the AeroSIM C – Flight simulator. In this PC-Program
various MikroKopter models can be flown like in reality. The same transmitter can be used, which is later also used for
the control of the ARF-MikroKopter.
With different training programs in this simulator your flying can be trained and improved.
HiSystems GmbH Page 5

Battery (LiPo) – General information
ARF-MikroKopters use Lithium-Polymer-Batteries, called LiPo. The ARF-MikroKopter is designed for the use with 4S
(14,8V) LiPos. The right LiPos can be purchased through us.
The ARF-MikroKopter monitors the battery during the flight. If the voltage gets low, a warning tone will sound from the
buzzer on the Kopter.
This alarm is also signaled by an existing telemetry transmission on the transmitter (with the HoTT system) or PC (when
viewing in the MKTool OSD).
Once this alarm sounds, land immediately and load or change the LiPo..
Continuing the flight with a warning signal can permanently damage the LiPo and the Kopter could crash.
After landing the Kopter and turning off the motors the connection between LiPo and Kopter should be seperated. Keep
the battery pack out of the A F-MikroKopter if that one is not used (e.g. storage or transport). That avoids a fully
discharge of the battery.
Do not charge the Lipo directly after landing. Let the LiPo always cool down. Improper handling of LiPos causes burns /
explosion hazard! Do not use damaged or defective LiPos!
Before using the Lipo the first time it must be fully charged!
The first charge of LiPos, depending on the charge level of the individual cells and operation / performance
of the charger been used, will take up to several hours.
The proper charging and discharging of the cells / LiPos can not be monitored by us. Any warranty is
excluded for incorrect charging or discharging.
Safety rules for LiPos
Lithium-Polymer-batteries (LiPo) require particulary careful treatment. This applies to charging, discharging, storage and
other handling. Incorrect usage / treatment of LiPos can cause performance problems, explosion, fire, smoke, poisoning
and other problems.
Do not cause short circuits as permanent short circuits lead to the destruction of the battery. High temperatures and
possibly spontaneous combustion can be the result !
Each charge / discharge and storage at too high / low temperatures reduces the capacity of the battery. The
recommended temperature range for charging and storing LiPo - batteries is 0-50° C.
A battery is a wearing part. Please be aware that batteries will wear out with use, and flight time will decrease.
For charging LiPo batteries the approved charger with the appropriate charging cable must be used. The max. loading
capacity must be limited to 1.05 times of the battery capacity.
(Example: 5000mAh Akku = 5250mAh max. loading capacity)
Use for charging and discharging of LiPo batteries only the especially designed charger / discharger.
The battery temperature should not rise above 70°C during the discharge.
Make sure that the number of cells and the charge voltage are set correctly. A voltage above 4,25V per cell must be
avoided otherwise the cell will be damaged permanently.
Further information about the settings get out of your instruction manual of your charger / discharger.
The battery which need to be charged must be while charging on a non-flammable, heat resistant and not conductive
surface ! Combustible or flammable materials need to be away from the charging spot. Charge batteries only under
supervision !
To store LiPos they should have a charge level of around 10-20%. During the storage the LiPos should be reviewed
regulary. This is easy with a LiPo-Tester. If the voltage of the cells go down to 3V they must be necessarely charged.
Deep-discharge and storage in discharged condition (cell voltage less than 3V) makes the battery useless..
The foil / outer shell of the LiPo can be easily damaged by sharp objects such as needles, knives, nails, etc. If the foil is
damaged it makes the battery useless..
Mechanical shocks e.g. throughout dropping, hitting, bending etc. can also make the LiPo unusuable.
Do not use damaged batteries under no circumstances ! Damaged or exhausted batteries are hazardous waste and
must be disposed accordingly.
If a LiPo is damaged, avoid any direct contact with the electrolyte. By contact with the skin, eyes or other body parts you

need to clean or rinse it immediately with plenty of clean and fresh water. Then a doctor should be consulted.
Charging the LiPo
Only charge a LiPo with an appropriate charger and integrated balancer.
The necessary settings can be found in the manual for the charger.
It is absolutely necessary that the recommendations in the instruction manual be followed.ger. After use the
LiPo should cool down before the next recharge.
The LiPo in the A F-MikroKopter consists of multiple internal cells. In addition to the cable with the Deans connector
another jack, the balancer, is connected with 5 cables to the LiPo. In that case the individual battery cells are monitored
during charging. With properly set values on the charger, charging the LiPo will be finished at a charge voltage of 4,22V
per cell.
The settings you need to charge a LiPo can be found in the manual of the charger.
Example: Connection to a obbe POWE PEAK charger:
What does the inscription mean on the LiPo?
Example: 5000 / 14,8V / 4S1P / 20C / 4C Charge
5000 => Capacity of the Lipo (here 5000mAh = 5Ah)
14,8V => Voltage 14,8Volt
4S1P => 4S = 4 cells are connected in series / 1P = no further cell is connected parallel.
20C => Maximum current of the Lipo. This is calculated as follows: (Capacity/1000) x Max.
current (5000/1000) x 20 = 100A).
4C Charge => Maximum permissible charging current. A 5000 LiPo should be charged with max. 20A
(4x5000mA).
For a longer life LiPos should be charged only max. 1C.
Using B D (Robbe)
If a obbe charger is used to charge the LiPos a BID-Chip can be
assigned to each LiPo. This BID chip stores all the relevant data for
charging the battery. When charging a LiPo, the corresponding BID-Chip is
connected to the charger. This gives the battery charger the necessary
battery parameter for specific LiPos.

Final Assem ly
First at all the landing gear, the battery holder, the propellers and a suitable receiver need to be assembled.
For the first start-up the propellers should not e mounted.
An assem ly of the propellers can e done just efore the first flight.
For the assem ly you need the following tools:
•Phillips screwdriver (Size PH1)
•Screwdriver
•ing spanner (SW 8)
Mounting the battery holder
The battery holder is composed of multiple components which can be
easily assembled.
First the narrow hook-tape need to be threaded into the top plate.
Important: The soft side needs to face upwards.
The second self-adhesive hook-tape need to be applied to the lower plate
as shown in the diagram.
Once this is done, the top and bottom plate with the 9 Aluminium spacers,
4 rubber bumpers, 5 plastic screws and 9 plastic nuts can be assembled.

The completely assembled battery holder needs to be mounted on the bottom side of the ARF-MikroKopter. For this
purpose the cover must be removed from the Kopter. Now the battery holder can be fixed with the 4 supplied metal
screws (M3x16).
Attention: The opening of the battery holder must point to the LiPo cable.
(seen from above to the left)
The cover is mounted via 4 metal srews (3x10) to the frame.

Assembly of the landing gear
The landing gear "Hilander-26" can be mounted at any rigger. You can choose, if you want to mount 3, 4 or more landing
feet.
When using a camera, the front rigger #1 should not have a landing gear (it will block the view of the
camera).
The numbering of the riggers is in a clockwise direction beginning with the different colored front rigger.
Example:
„ARF-Mikro opter“ with 8 rigger
=> Landing gear on rigger 2, 4, 6 and 8 (short riggers)
Assem ly step 1 - 4:

Connecting the receiver
One 3-line PPM cable and one1-wire data cable (for telemetry transmission) are used to connect the receiver.
(Those both cables come out on the back and the bottom side of the Kopter.)
Here, e.g. a Graupner G -12/G -16/G -24, Jeti- MK2 or a similar receiver with PPM sum signal can be connected
directly. The data cable for the telemetry transmission is plugged into the appropriate port of the receiver (if present).
A telemetry transmission of the Kopter to the transmitter is possible with the Graupner HoTT-System.
No other sensors are required.
An appropriate mount for the G -16 receiver is applied to the ARF-MikroKopter. This will be hooked up with the receiver
to the back side of the battery holder.
You need to connect:
•the three-wire PPM-Connection PPM-Sum-signal
•the telemetry-cable to the telemetry input of the receiver (if available)
Example installation with receiver GR-16:
In case that a different transmitter and receiver are used, the receiver must be bound to the transmitter and
set to the required sum-signal. Please refer to the manual of the transmitter how to activate the sum-signal

Propeller assembly
Propellers should not e mounted for the first start-up of the Kopter.
The ARF-MikroKopter comes with two different types of propellers:
•Propeller EPP1245 (for training flights)
•Propeller CFK 12x3,8 (for flights with payload)
Both propeller types (EPP/CFK) are mounted in the same way.
The order of the necessary parts are as follows:
1. Lock washer
2. Propeller
3. Black washer
4. Self-locking nut
During the assembly it should be ensured that the propellers may have different directions of rotation
and be mounted in an alternating arrangement.
Left-rotating propeller (top side) Right-rotating propeller (top side)
The mounting order of the propellers is as shown:

nserting the battery
The ARF-MikroKopter comes with four batteries: LiPo 14,8V / 4S / 5000 / 20C and a Y-adapter.
The batteries can be used alone or to extend the flight time in pairs.
When connecting a LiPo it can cause sparking at the plug, which is normal.
To keep the battery tight in the holder the hook and loop tape should be placed tightly against the lower
hook and loop tape.
To operate two 5000 LiPos together on the A F-MikroKopter, those can be connected via the included Y-cable. In this
case proceed as follows:
If two of them been operated in parallel it is important to ensure that both batteries have the same charge. If
two differently charged batteries will be connected together (e.g. one battery is fully charged and the
second one is half empty) it may result in damage to both batteries and heating.
1. First at all slide both LiPos over each other into the LiPo-Holder and secure it with the hook and loop tape on
the battery holder. The connection cables of the LiPos face to the left.
2. First connect the Y-cable to the sockets of the LiPo power cable.
!!! ATTENTION !!!
After the first plug is connected to the socket, the full LiPo voltage is at the second connector of the Y-cable.
Here shorts must be avoided.
3. Connect the socket of the Y-cable to the connector of the ARF-MikroKopter.
emove the LiPos in reverse order.
Do not use the Y-cable to charge the LiPos! Each LiPo must be charged separately using an appropriate
charger.
