Ok, this is the 2nd one of these I bought.  Sent the first one back because one prop would never stop spinning.  This one the headlights stopped working in the first 3 minutes of flight. And no, it was not because of a crash. But speaking of crashing, this unit is nowhere near as stable as the Hubsan X4.  Now, you put THAT one in a protective cage like this and you would really have something.  Here, all you have is a cage that protects the flying unit, but the flying unit is not very good to begin with.
