Academy had several drivers competing at the Worlds in the 4WD class with their SB V2 Pro chassis. A couple of them were testing a new saddle-pack, mid-motor conversion chassis that looked very promising. It features a carbon fiber chassis and upper deck, an aluminum motor and center diff mount, and carbon fiber battery straps with knurled thumbscrews. Academy is distributed in the US by MRC; no word yet on whether MRC will offer a conversion kit, or release an all new car based on the prototype.
