Built for extreme all-terrain action, the 1/10 scale ARRMA GRANITE 4X4 MEGA 550 Brushed RTR amplifies the excitement of your monster truck RC bashing as only an ARRMA RC truck can. This RC monster truck 4x4 rides tall on massive, high-traction, multi-terrain tires. They turn the rugged powertrain’s 30+ mph speed potential into turf-pounding, fast RC truck fun almost anywhere you please. Go ahead and send it. From the full-time 4WD transmission to the large diff gears, every part of this big RC truck is built to survive brutal blasting. ARRMA also gives fast, easy maintenance a whole new meaning with the ingenious modular chassis design. You can reach almost any component by removing just a few screws. With the included Spektrum 3-channel radio, monster truck remote control is easy for anyone. New drivers can set the throttle limits at 50% or 75% until ready to use the full speed potential. The recommended, high capacity NiMH battery delivers enough performance and run time to make this the one of the best RC monster trucks for any skill level. You can also upgrade to 2S LiPo power and take your RC 4x4 off-road fun to the next level. Fully assembled and ready-to-run, the ARRMA GRANITE 4X4 MEGA 550 Brushed RTR needs nothing more than batteries and a charger before it’s GO time!
