Doubleplanks 16 sent me this question, which I think might help clear up some confusion about the Kangaroo Flip:
Doubleplanker16:
"When people say the kangaroo flip is a double flatspin i think i disagree....to my knowledge it looks more like a little off axis double linclon 180?? whats up with this?"
My Response:
I wish I had a better video of the trick, but the best shot of Jon's trick was in a streamed video off some sweedish website. Honestly, the rotation is so different that I'm not sure you could classify it as either.
I've seen another video of some European guys trying it (one actually pulled it off, quite impressive) and they warmed up with double backflips. Apparently, the trick is thrown like a double backflip, except you twist to the side as if you were about to go into a flatspin or rodeo . With the double backflip rotation, Jon in the video gets to 90 after the first flip, then does his second to come 180. Technically, this would be a flatspin, as he doesnt get completely inverted, as in a rodeo, lincoln or an underflip.
So, the kangaroo flip is more of a flatspin than anything else. While the backwards rotation is a double backflip, the sideways is only a 180, so its not two flatspin 540's linked together. Two flatspin 5's would make a doubleflatspin 1080, while Jon's trick is really more of a double flatspin 900.
So what would a true double flatspin 1080 look like?
This is my best guess.
Thanks for the good question, don't ever hesitate to message me if you have one, I'll try my best to answer it.
