You have to keep tryin a lot of times and it will work perfectly at the end. I've seen it like 10 times, its not that good thought... I hope they will put the video up to dl with all the runs and a little bit editted cause its kinda raw stuff now, and only 10 mins or so.
Good job to NS stuff anyway, and im sure it will get better and NSTV will be something incredible.
I do wheelchair freestyle you should see me
