Today, Monday after an estimated 20 charges, the full charge battery only lasts for max. 1 minutes flight time.
Where the helicopter itself barely higher than 1.5m flying at full throttle.
After that is "fly" a few centimeters above the ground possible.
Without the ground effect, the helicopter does not fly. (Eg Start on the table and leave, then the amount is holding no longer possible)
The helicopter was loaded with the appropriate USB cable.
Flying by helicopter is fun.
It is also robust and forgiving hard landings.
Unfortunately, the battery is high too bad, so the fun does not last long!
I'll send the helicopter back.
