Overview


The STX2® 2-channel radio that drives the GRANITE™ 4X4 3S BLX RTR has a lot of the same functions discovered in high-end 2.4GHz radio systems —throttle and steering reversing, throttle and steering travel adjust, throttle restricting and more. It's paired with a factory-installed SRX200 2-channel waterproof receiver.


The brand-new RC system releases you with confidence into terrain-commanding beast truck excitement. Hard parts, amazing 3S BLX power, and high-quality ARRMA® engineering conquer anything that stands in your course. The GRANITE™ 4X4 3S BLX discovers incomparable traction on any surface as it carves the landscape with ground-thrashing full-time 4WD. Accuracy aluminum, difficult steel and composite products all combine to make this brushless beast a lorry that's all set for hard-hitting action, right out of the box.


Power, electronics, and front and rear differential modules are easy to gain access to and can be gotten rid of quickly for maintenance. They ensure you spend more time bashing and as low as possible in the workshop. The primary differential gears have actually been super-sized with TOUGH, large pitch gears to withstand huge torque. The differential internals feature full-metal, straight-cut gears for equally hassle-free operation.


Built to take in extreme all-weather thrills and spills with its independent suspension and oil shocks, the GRANITE™ 4X4 3S BLX manages it all — everything from quick speed goes to snow and mud chucking. No matter where you bash, you'll remain stable and in control. The shocks feature a keyed spring perch and self-bleed style. They're easy to keep, yet offer the performance required for fantastic all-terrain handling.


Four dBoots® FORTRESS tires on black chrome multi-spoke wheels offer the GRANITE™ 4X4 3S BLX excellent bite on a wide variety of surfaces. ARRMA® has also installed an adjustable multi-height wheelie bar as standard.


The strongly styled truck body looks great while bashing and even better up-close and personal, with great attention to information on the decal and body aesthetics. Pick orange or red trim schemes. The ARRMA® GRANITE™ 4X4 3S BLX RTR requires just a battery, battery charger, and AA transmitter batteries.
