I still haven't got my airboat ready yet.  It just needs the radio installed.  I guess it could go on the snow.  It's a Big Swamp Buggy.  I got a smaller one too that I haven't tried yet.  It doesn't look like as much fun.  I think the swamp buggy would unload a bit when it is moving too, but I think the low pitch and big dia. props are the fad for them.
