RE: buggies in snow
who the hell has snow in the middle of july.
i/we run our monster trucks in it all the time (put the ski's on the front, duely adapters on the rear, and 4 paddles talk about fun) anyway, either plasi-dip the radio gear or ballon it and you shouldnt have a problem. blow it off before it melts to avoid the water.
one thing to note
although the eletroics might make it, the plastic becomes EXTREAMLY brittle at very cold temps. bumps/"crashes" even minor ones that your buggy/truck may take durring the summer with out batting an eye will have a strong likelyhood of breaking something. (least thats been my experience)
