Red Bull Helicopter does back flips!

not suspicious at all. 3 types of rotor heads...Rigid, like this helo, semi rigid, like Lynx, and articulated, like Sea king, Jet ranger etc. The lack of flapping and dragging hinges on the head, allow you to do this.....just do NOT try this in a helicopter with an articulated rotor head! you will NOT succeed! lol

Hmm the edditting looks suspicious to me. Whn it is upside down surely lift will be nill so it should fall like a stone?

awesome :O

That chopper is really drunk. Who let him out?!

that moment on 0:25 it is quite frightening!

keep on the sound from te engines!!!!

So can an apache, i've seen displays several times with helicopters flying upside down. If a helicopter couldn't - then neither should an aeroplane be able to. They fly using the exact same principles but an aeroplanes wing is fixed.

Awesome video by the way! Where is this aircraft based?

@hafstrat any proof to support this theory? i think not! lol

That is not true the Augusta Westland Lynx used by the British Armed Forces can do barrel rolls and loop the loops, so get your facts straight!

Wow. I learnt something today. :-)
