Those are cool. I have seen the screw drive before, but can't remember where!

wow!

Probably not so smooth on the trails or on the backbone, but sure looks unstoppable!

Those are cool. I have seen the screw drive before, but can't remember where!

I think a toy company like Tyco had an RC amphib out a couple of years ago that used screws like this to propel itself in the same fashion.

I asked the wife if she remembered seeing it, and she says it was on a discovery channel show / arctic expedition!
