Fast, fierce, factory-assembled and fully equipped, the 2S capable ARRMA® SENTON™ 4X4 MEGA RTR Short Course Truck is ready to bash right out of the box. Its Spektrum™ STX2® radio with SRX200 receiver includes many of the same features found in high-end 2.4GHz radio systems — throttle and servo reversing, throttle and steering travel adjust, throttle limiting and more. The 12T 550 brushed motor powers the SENTON™ 4X4 MEGA RTR to exciting bashing speeds. Waterproof* electronics and dBoots® Fortress tires carry it through any terrain in any weather. The ingenious ARRMA® modular chassis makes servicing fast and easy. Motor, motor plate, slipper clutch assembly and gear cover are all contained in a single module that can be removed from the chassis by taking out just one screw. Similar modules for the electronics and diff units add to the ease of maintenance. Enjoy full-scale short course truck looks and lots of mud-blasting, dirt-roosting fun with the SENTON™ 4X4 MEGA RTR!
