Check Hacked Gadgets for more images as well as a video of the rollercoaster. Sounds like fun but I don't know if I would trust myself building such a thing.

May be it is me (I am still a little out of it from having some teeth pulled yesterday) but this doesn't make sense:

Height: 17 feet
First Drop: 20 feet

I'm guessing that the tallest part is actually 17 feet high, kinda like the portion in the picture I posted. If you watch the video they obviously go down a hill so that is probably considered the drop, but is probably only a foot or so tall since it is hardly off the ground.

That's just my guess though.
