You do fly in your living room without problem: it is extremely stable even if you know nothing. It comes with a rechargeable battery on a USB jack: your PC or USB charger for your phone, for example. In the transmitter just put 6 batteries (not included): I personally put rechargeable batteries LR6 (max 4 euros in coupon at Lidl ..). The flight time is about 5 minutes and it is really fun.
With practice it is placed on a square of 20 X 20 cm, and even we get to go down a hallway .. Also with two LEDs it is nice to fly in a nearly dark ..
International flights: yes to two conditions: dark (little light so that the infrared works) and WITHOUT WIND. One can indulge in these conditions.
The Syma mark (I already have 3 different models) is well known in the elevator of RC helicopters: it is between the toy and the top of game model. I have never been disappointed ..
One more thing: about the strength: I do not know how many times I hit the ceiling, a wall of items:
never breakage, it is very strong light metal and flexible plastic, the blades are very flexible and does not substantially break. We find all the spare parts on many sites sometimes with free shipping ..
Thank you for reading and good flights ..
