There was a 1/110th scale "
Zubr-class" hovercraft model on Hobbyking, can still find it on Aliexpress. I loved the idea of an RC hovercraft as a kid, they are the perfect demo toy for an indoor mall.
The videos aren't encouraging though, it seems to lack the power to hover over water, instead just kind of floating and blowing bubbles through the skirt. Maybe some power upgrades would fix that issue. Edit: Or just moving some weight rearward, it appears to be front-heavy.
I'm not sure the rubber-skirt hovercraft concept "works" in miniature. They need exceptionally flat surfaces, perform poorly even on perfectly still water, and grass is out of the question.
They don't seem to perform any better than RC airboats. Most RC hovercraft seems like they would work just as well if the hull were a big block of plain styrofoam with air being blown under it, which is also (perhaps unsurprisingly) a popular design for DIY model hovercraft.
Edit: thinking about it, the problem seems to be that an RC model just doesn't have enough surface area underneath it to "trap" a meaningful cushion of air.
The perimeter:area ratio of a 1/110th scale RC is 110 times worse than on the full sized model, this means the miniature is losing air through the skirt 100 times faster than the full-sized model does, relative to the amount of lift that air provides before it escapes.
Also interesting, a hovercraft must have displacement, in the form of a "depression" in the water underneath it. It makes sense that a miniature hovercraft will struggle to maintain this depression, and instead sink until its own buoyancy through traditional displacement is enough.
