Realmente muy quemado, me hace acordar al comercial clandestino de quiksilver que si no me olvido se llama bomb, pueden encontrarlo en youtube, saludos
Yes, it does back flips. It is a Eurocopter BO-105 CBS 4 Twin engine helicopter. Stock model with a Rigid Rotor system, the fixed rotor is why it can do aerobatics.

Red Bull Crashed Ice smashed into Quebec for the city's third edition of the fastest sport on skates! Finland's Artu Pihlainen took home the top prize while 85,000 fans lined the course - and undoubtedly snapped over 85,000 pictures - of a jaw drop course that wowed spectators and thrilled/punished the athletes.
