a beautiful flying machine that can fly vertically only. The autonomy is limited and it is regrettable that the batteries are not provided (always embarrassing when you make a gift of not being able to try it right away). However, the ability to stop the vehicle from the charger is handy. Similarly, the small offset (3 seconds) between when it starts and the actual start allows for time to remove by hand. A thoughtful toy in the whole and that should appeal especially to boys.
