It's not a FC but it's a remarkable sound...well worth watching.
Go here.

 

Sigh,

 

Well aside from all the focus on helicopters, slow motion, and red bull it's a good video of a 4-rotor. I can barely afford to budget for an FC build. Must be nice to be able to be pro, get an fd, have a 4-rotor built for it, and then have some mountain pass in New Zealand shut down for you. If it sounds like I'm hating on the guy I'm not... He's just my new Justin Bieber; he gets the things I'll never have lol. Good find though.

 

did u just call madmike justin beiber?!

 

mad mike is nasty! who needs turbo when you got 4 rotors?!

 

yeah, some people do just get lucky in life. others work for it, which he did. but there was some luck still involved.

 

You can tell it was a ton of takes since the back wheels change all the time.

 

Here's one I like, not rotary or rx7 related, but the same type of up hill thing.

 

or all the tire marks? its just like all ken blocks gymkhana vids. who cares, its still cool
