SaFetY precaUtlonS
General
- Read the Operating Manual carefully and keep it for future reference.
• Familiarise yourself with all the instructions for flight operation.
This model is not a toy!
• This radio-controlled model aircraft not a toy. Learning how to control it correctly is a gradual process.
• Children under 14 years of age should be supervised by an adult.
If you are not yet proficient with model aircraft, we suggest you approach a more experienced model pilot or a model-making club about making your first flight attempts.
Flying a radio-controlled model aircraft a fascinating hobby. However, it has to be practised with the necessary caution and consideration.
A radio-controlled model aircraft can cause damage and injury in an uncontrolled flying mode, and the user is liable for any such incident.
As a manufacturer and distributor of the model, we have no influence on the correct handling and operation of the model.
Make sure that you have sufficient insurance cover when practising your hobby or take out a special insurance for model aircraft. The contact address for this is Deutscher Modellfliegerverband e.V. Rochusstr. 104 – 106, 53123 Bonn.
Only a well-maintained model will function properly. Only use approved spare parts and never improvise with any unsuitable items.
It is the user's responsibility to ensure that the model is functioning correctly and that all nuts, bolts and screws are tightened.
Keep the model well beyond the reach of small children. They may unintentionally activate the model and cause themselves injury with it, or they may put batteries and small parts into their mouths and swallow them.
Preparations
Never start flying before you have made sure of the following points:
• Pay attention to visible damage on the model, remote control, battery charger, and lithium battery.
- Ensure that the model is functioning correctly and that all screwed and plugged connections are fitted precisely and tightly.
- The flight battery must be fully charged and correspond to the correct voltage. Only use new/fresh batteries for the transmitter.
• Make sure that all servos respond correctly to the signals of the transmitter.
• Always check the radio operation before starting the model.
Flight operation
The model is primarily designed for indoor flights since its low weight and unstable flight position resulting from the construction type make it very susceptible to air movements.
Moreover, the components are not dust- and moisture-proof.
Do not fly any longer than one battery charge
Afterwards, the model must cool down for at least 5 minutes.
Then recharge the battery. Avoid deep discharge in any case.
General information
• If you have little or no experience with model aircraft you should practice with a flight simulation program first.
- Ask experienced model pilots for advice with the fine settings of your model aircraft.
• Familiarise yourself with the control functions of your trnasmitter.
- Start your first flights, standing behind the model and looking in the flight direction. In this case, the control reaction equals the controlling direction.
- Also familiarise yourself with the movements of the model, when it flies towards you (response opposite to the control direction)!

Experienced pilots can start the quadcopter on the „cool“ way. Throw the model into the air (approx 3-5m). Move the throttle lever up, and the model stabilizes it self in the air. Practice this method best on a soft Lawn / meadow.
