ARRMA sent over a few pics of what looks like a highly modified version of their Raider buggy built to take on the sand! Jami, one of their designers basically sat down for a few hours and created this thing, and it looks sweet! Looks like they chopped the cab, moved some parts around, and added some paddle tires.
