Very high quality product. The box contains the heli, transmitter and some parts (charger, screwdriver, blades). The heli needs to be paired with transmitter (it is simple by using the button on heli's pcb). Then it works fine. Only tried on a desk, have not flown. I have beginner helis, but it is for professionals. Shipping and delivery were fast. Seller and item are highly recommended. Thanks a lot.
