About 5 minutes flight time and 30 minutes charging over USB. Unfortunately the battery is not replaceable, so you can't buy a bunch of it as I did with my ZMR250 copter. But if you buy 6 of the tiny things, you can fly without pause :-)

Great and thanks for the answer. It is hard for kids to wait for the batteries to fill up. You can imagine that they have no patience ...
