I already did one, sure it's very fun and fast, but it's not....a flight. It can do any air evolution (Hovering and Tork roll too) but it fly as it wish...all you can do is help it..it will anyway do what it wish, but with style p.s. the foam + carbon structure cost maximum 15 $, what it's not writted is the cost of electronics.. With Engine, speed controller, servos ect.. the cost is about 250/300$
