9. Flight preparation
a) Flight battery charging
•
Remove the flight battery (E) from the race copter before charging.
• A suitable USB mains unit or USB cigarette lighter adapter (neither enclosed) may be used for power supply to the
enclosed USB charging cable (D). The output current must be at least 500 mA.
• Alternatively, the USB port of a computer or USB hub with a dedicated mains unit that can supply a current of
500 mA per port can be used.
• Connect the USB charging cable from the delivery to the USB power supply with its USB plug. Then connect the
small plug of the USB charging cable to the corresponding socket of the flight battery. Observe proper alignment of
the plug (the plug contour must match the socket of the charging cable).
• If the battery is not defective and power supply is warranted, charging commences. This is signalled by the blue
LED in the USB charger. Charging of the battery will take about 30 minutes.
• The following LED displays are possible:
- LED is permanently lit: The battery is being charged
- LED is off: The battery is full or fully charged
b) Inserting batteries into transmitter
• Open the battery compartment (9) at the bottom of the transmitter (C) with a suitable screwdriver. Insert 3 x 1.5 V
batteries type AAA into the battery compartment. Please observe correct polarity (+/-) as indicated in the battery
compartment. Close the battery compartment. See illustration Fig. 1.

If the batteries are low the Power LED (2) will flash and it will also be indicated by a frequent beep tone. In this
case return the race copter to the ground. Disconnect the flight battery and switch off the power of the transmitter.
• Insert new batteries into the transmitter.
