b) Before operation
• Check the functional reliability of your model and of the remote control. Watch out for visible damage such as
defective plug connections or damaged cables. All moving parts of the model must run smoothly, but should not
have any play in their bearings.
• The aerial wires of the receiver should not be wound up, folded or shortened.
• Charge the flight battery necessary for operation as well as rechargeable batteries in the remote control according to
the instructions provided by the respective manufacturer.
• If batteries are used as the power supply of the transmitter, make sure that there is sufficient remaining capacity
(battery tester). If the batteries are empty, always replace the complete set, never replace individual cells.
• As power source for the wall power supply of the provided plug-in charger, only use a 230 V/50 Hz mains socket of
the public power supply. Never try to operate the wall power supply using any other voltage.
• Before operation, always control the settings of the trim slider on the transmitter for the various steering directions
and, if necessary, adjust them.
• Always switch on the transmitter first. Only then the flight battery of the helicopter may be connected to the receiver/
controller unit. Otherwise, the electric-driven helicopter can show unpredictable responses!
c) During Operation
• Do not take any risks when operating the product! Your own safety and that of your surroundings depend on your
responsibly handling the model.
• Improper operation can cause serious personal injury or material damage! Therefore, during operation, make sure
there is sufficient safe distance to persons, animals or objects.
• Fly your model only if your ability to respond is unrestricted. Tiredness or the influence of alcohol or medicine can
lead to false responses.
• The motor, the receiver/controller unit and the flight battery can heat up during operation. Therefore, wait for 5 to 10
minutes before re-charging the flight battery or before flying with a spare flight battery. Especially the drive motor and
the speed controller must cool down to room or ambient temperature.
• Always leave the remote control (transmitter) turned on as long as the model is in operation. After landing, always
disconnect the flight battery from the receiver/speed controller first. Only then may you turn off the remote control.
• Do not expose your model or the remote control to direct sunlight or excessive heat over a long period of time.
