10. Charging the flight battery
Before the final assembly of the model, you should charge
the flight battery (1). An appropriate plug-in battery charger
(2) is included in the delivery.
Connect the flight battery with the connector that is
protected against polarity reversal (3) of the plug-in
charger. The catch (4) on the charger plug must arrest in
the groove of the accumulator plug.
Now connect the plug-in charger to a power socket (230V/
AC, 50Hz).
For photo-technical reasons, the charging cable of the plug-in mains unit is illustrated in the wound-up
state. Before the first use, the cable retainer should be opened and the cable be unwound.
Important!
The charging process is completed after approx. 2.5 to 3 hours. After that, the rechargeable battery has
to be disconnected from the battery charger and the battery charger disconnected from the mains
socket.
If the rechargeable battery is only partly discharged, the charging process must be stopped earlier. For
that purpose, check the temperature of the rechargeable battery manually in regular intervals. Once the
rechargeable battery is completely charged, the charging current is completely transformed into heat.
Thus, the temperature of the rechargeable battery increases noticeably.
Attention!
A fully charged battery or a switch*off of the charging current is not automatically identified.
