Very impressive. What size C4 is he using and did you modify the chicken loop / through of the bar? I have an 8 year old who is keen but only weighs 30 kg.
kid rips.
good on the parents for getting him on the water.
good on steve for supplying kick-arse kites.
yewww...
Morandi
As Steve said i havent had to adjust anything on the 2012 c4s and if you are looking for some kites or just some advice email me. 
... well done Aro, nice work on the editing (and ripper kiting btw, kick my arse on the water for sure).
My (hopefully helpful) comment is abit techy and really nit-picky but its about the slow-mo action. Get your dad or whoever helps you with the editing to read this and maybe explain it better than I have written here.
When I watched your video I noticed not all the slow-mo bits were totally smooth, sort of a little choppy. Don't get me wrong, its not a bod thing, just something I noticed and something I always wanted to get better at myself. I wanted to get my little video projects to the next level and look better but I wasn't sure how. I did a little experimenting and found a little technical thing you can do.
What I found was keep the speeds you reduce the footage too at even steps to the original footage frame rate. The slower you make it, the choppier it looks. Sometimes you may want this as an affect or a certain look, and can look cool but sometimes you don't.
To explain myself a litte, I use Sony Vegas and what I found is, keep the steps you slow your footage down to, even steps so that the frame rate is a multiple of the original footage. What I mean by this is, say original footage is 25 frames per second (which is normal for alot of video cameras), then edit it to exactly half, or exactly 1/4, or 1/8th etc. From my experiments, keeping it in steps like this rather than say, making it 30% of full speed, but rather make it 25%, or 12.5% etc etc.
When it comes out when you finish, you find the slow-mo is a little more even and appears smoother. If you slow it down really slow, no matter what its gunna look choppy but you can make it a little more even and more artistic. The other way is to use extra software or plug-ins but can be expensive.
Do your own experiments and find the one that works for you and you'll find your videos will look just that little bit more cooler!
cheers for now,

Puetz.
thanks for the advice we will definately try that in my next movie.
and i will have a few more tricks by then
