yeah, it really is a cool piece of R/C thinking and design. One incredibly powerful electric motor and a very light chassis.
Unfortunately it seems like the guys behind it can't seem to get their act together enough to actually get either fully builts or kits out to an eager public. They've even had to shut down the HydroFoam forum because they kept getting asked the same questions all the time and had too huge an amount of traffic

If they ever manage to get it to the marketplace I'll be buying one (or maybe 2 or 3)
