Woah dude that's awesome!
I tried to do a little bit of that in mine, like my nephew was going to jump of the curb and go really far, but I just couldn't do it lol. That's some great stuff, I've seen a vid that does the same thing, I'll just find it...
There's some more at the bottom too.
Hope this helps and keep at it, what I've seen looks awesome!!
And heheh, I inspired people!!
