10. Charging the Flight Battery
The flight battery is charged with the remote control transmitter. For this, open the flap (1) on the front of the transmitter
(also see figure 1, item 9), fold it to the left.
Then connect the flight battery (2) to the charging cable (3) in the battery chute. The plugs are protected against
polarity reversal. Do not use any force when plugged in. Once the rechargeable battery has established contact, the
red charging indicator lamp lights up (see figure 1, item 2) and signals correct charging.
When the charge control lamp goes out after about 30 to 40 minutes, charging is completed and the rechargeable
battery must be removed from the charge cable. Return the charge cable to the battery chute and close the battery
chute's flap. Observe that the charge cable is not caught and damaged by this.
The transmitter does not have to be switched on for charging. If the transmitter batteries grow too weak for
proper charging, the charge control lamp will grow dimmer. You may switch on the transmitter briefly during
charging for test purposes. If the green function control lamp flashes and the transmitter issues warning
sounds in a quick sequence, the batteries are already too weak for proper charging of the flight battery.
Charging duration depends on the remaining charge of the flight battery and the quality or residual capacity
of the transmitter batteries used; it may therefore vary strongly.
Caution, important!
Disconnect the fully charged rechargeable battery from the charge cable without delay and do not leave it
connected to the transmitter for longer than necessary! Charge the flight battery only with the help of the
remote control transmitter and do not use any chargers that are not suitable for single-cell LiPo batteries.
Charging will only start if the flight battery has a residual capacity of less than 90%.
