Great helicopter. Takes an indoor beating pretty well too...just need to make sure you shut it down as it crashes.
It is stable and has good range for indoor use. flight time of about 10 min on full charge. Option to charge from USB saves on battery recharges.Easy to fly from room to room, through doors, land on tables, etc. Very sturdy for something so light.
In case you broke rotor propeller(s) package comes with two spare for main, one for tail and small philips screwdriver!
None so far. Only played with it for a few days.
Other Thoughts or Suggestions:
This heli is *not* a toy. It is a very well engineered flying machine that takes some technical know-how to properly maintain. There are a myriad of things you can do to make it not fly correctly, but if you learn how to diagnose the symptoms it's easy to fix.
