From Arrma:

Making your move into 1/8 scale buggy bashing has never been easier. The TYPHON™ 4X4 MEGA 550 Speed Buggy brings exciting TYPHON™ buggy style to a 2S LiPo-capable brushed version that’s ready for action in all terrain. Its 12T 550 brushed motor supplies rippling muscle for rock-jumping speeds. The waterproof* electronics are ready for any weather. dBoots® 2-HO tires on tough, multi-spoke wheels find traction on any surface. The Spektrum™ STX2® radio with SRX200 receiver offers many of the same features found in high-end 2.4GHz systems — throttle and servo reversing, throttle and steering travel adjust, throttle limiting and more — for the ultimate control. Precision aluminum, tough steel and composite materials come together for an easy-to-maintain, super-durable vehicle design whose high downforce wing and low center of gravity, with wide arms and narrow wheels and tires, improve handling over race tracks, trails, muddy courses, skate parks, and more.
