7   TrIM aDJUSTMeNT oF The CoNTrol

The correct trim is a basic requirement for fault-free flying behaviour of the quadrocopter. 

Its adjustment is simple, but it requires some patience and a feel for it. Please observe 

the following instructions precisely: Carefully move the thrust control up and raise the 

quadrocopter approximately 0.5 to 1 metre in altitude.

7A If the quadrocopter moves by itself slowly or quickly to the left or right …

press the roll trim gradually in the opposite direction.

7B If the quadrocopter moves by itself slowly or quickly around its own axis …

press the yaw trim in the opposite direction.

7C If the quadrocopter moves by itself slowly or quickly forwards or backwards …

press the nick trim gradually in the opposite direction.

7D If the quadrocopter rises too quickly or slowly …

press the thrust trim gradually in the opposite direction.

4   ChargINg The QUaDroCopTer

Attention:

 The battery and motor must cool down for 10 to 15 minutes before 

charging and after every flight. Otherwise they can be damaged. The charging process 

must be constantly monitored. Always ensure that the charging process takes place on 

a fireproof surface in a fire-resistant environment.

• Unplug the quadrocopter from the battery and switch off the remote control 

(4A)

.

• Remove the battery from the battery compartment (do not hold by the cable!) 

(4B)

.

• Plug the charger into a free USB port and connect the battery to the charger 

(4C)

.  

The charger flashes.

• The charging process starts automatically and must be continuously monitored.  

The charger flashes slowly during the charging process. (quick flashing indicates a 

malfunction – the charging process must be stopped immediately.) As soon as the 

charging process is complete, the charger lights up continuously. 

• Disconnect the battery from the charger and disconnect the charger from the USB 

port once charging is complete.

After a charge time of approx. 70 minutes the quadrocopter can fly for  

approx. 5-7 minutes. 

Warning notice:

 The battery does not normally heat up while charging. If it should 

become warm and/or changes to the surface begin to appear, immediately discontinue 

the charging process!

The remote control can be switched from Mode 1 (thrust/yaw on the right stick,  

nick/roll on the left stick) to Mode 2 (thrust/yaw on the left stick, nick/roll on the  

right stick).

To do this, push the mode switch 

(5A)

 for Mode 2 to the left (standard). Push the 

switch for Mode 1 to the right and turn the remote control 180°.

Important:

 Only switch with the remote control turned off.

6   STarT preparaTIoN

The thrust controller (the left controller on the remote control) must point down 

before being switched on 

(6A)

. Then set the ON/OFF switch of the remote control 

to the „ON“ position; the Power LED will flash red 

(6B)

 Place the quadrocopter on 

the ground so that the tail points toward you - 

WITHOuT connecting the battery! 

(6C)

. Only connect the battery with the connection cable when the quadcopter is 

standing 

level

 (e.g. on a table) Do not move the quadcopter when connecting the 

battery - 

otherwise, the quadcopter will not fly! (6D).

 Now the LEDs on the 

quadrocopter start to flash. Do not move the quadrocopter while the LEDs are flashing. 

The quadrocopter needs around 5-10 seconds to initialize the gyro and to establish the 

connection to the remote control. Once the LEDs on the quadrocopter are continuously 

lit, the connection to the remote control has been established. Now move the thrust 

controller forwards once all the way and back to zero again, the remote control beeps 

once and the quadrocopter is ready for use.

Warning!

 Always place your quadrocopter on an even horizontal surface – the control 

electronics aligns its neutral position to the subsurface!
