Transform your ARRMA GRANITE 4X2 BOOST 550 MEGA Brushed 2WD from budget-friendly basher to monster truck beast whenever you’re ready, thanks to an innovative, upgrade-ready chassis from the ARRMA design team of enthusiasts. Straight out of the box, this big RC truck is fully ready-to-run, with a 7C NiMH battery and USB charger both included — making it an ideal choice of first remote control monster truck. And like all real RC monster trucks, it’s got plenty of power and attitude. The included MEGA brushed motor system can reach 30+ mph, and the rugged chassis takes a high-speed pounding over off-road, dirt, grass, parking lot, paved and asphalt surfaces without even a whimper. The innovative modular chassis design is exclusive to ARRMA’s best RC cars and trucks, giving you instant access to every on-board component for effortless maintenance. While you’re learning the basics of fast RC truck control, you’ll love the throttle limiting feature of the included Spektrum radio. Set it for a maximum of 50% or 75% of full power to stay in your comfort zone until you want to cut loose. Then, once you’re ready, the ARRMA GRANITE 4X2 BOOST can deliver more extreme monster truck RC action. This “beginner” ARRMA RC truck has a brushless-ready design, easily upgradeable to a 3S brushless motor to go from bashing to all-out blasting. And with the 4X4 BOOST Transmission Upgrade Set (ARA210003, sold separately), the extra traction of 4-wheel drive is just ten minutes and three simple steps away.
