[Christian_83]

Hi, i think it was on the X i saw this very cool helicopter slow motion footage. I seem to remember something about "copter boys" or something like that. Some dudes, put a sony HD high speed camera on a rc helicopter, at shot some guys on a freestyle dirt track.
I tried to search - but no luck.
Anyone?
