Any homemade setup would require 2 esc's and a airplane "v tail" splitter. And you would need ESC's with a crawler mode....any esc with a reverse delay causes a problem with steering.
hobby grade RC wheels would have to be modified in order to not let water in.
Making the rest of the rig waterproof wouldn't be that hard, especially if waterproof electronics were used.

on the other hand, for a RC company to design something, I can see the finished product being $200-$250. If the tires were big enough (or chassis thin enough) to allow for good ground clearance, then you would have a RC capable of going on nearly any terrain.

anyway, Im still debating if I want to try a 1/8 RWD on road build this summer. Something RWD, with motor up front, solid rear axle and a pan car like chassis with a toy-hard plastic body.

I bought the nikko vaporizr, it will be delivered tomorrow. We have a lake nearby we take the kids to. sand/grass/dirt and water...perfect testing grounds for the vaporizr.
It is amazing that it costs $30. I recently bought a $30 rc buggy from walmart....it had a 6.4v lion battery and was very light...but only went 5mph! And it didn't even accelerate to that speed very well. The vaporizr is 4wd and nearly double the speed and even has a longer runtime!
The toy grade rc world is a strange place. There are a few models that stand out, that do as advertised and are great performance for the money. most though, are junk, underwhelming and underperforming. Some are just plain slow, some can't turn for crap and others have crazy short runtimes.
