1/7 BIG ROCK 4x4 6S BLX Ready to Run (Red) (ARA7612T2)

The ARRMA BIG ROCK 6S BLX 4x4 takes RC monster trucking to an epic scale, built on the renowned 6S BLX platform and expanded to an impressive 1/7 size. Ready-to-run with powerful Spektrum brushless technology, this large-scale truck combines rugged durability with intense 65+ mph potential when equipped with the optional speed pinion. The BIG ROCK’s crew cab body features eye-catching, scale detailing and durable black-anodized aluminum parts, while the massive dBoots RAGNAROK V2 tires provide aggressive traction on all terrains for unbeatable off-road handling.

Powering the BIG ROCK 6S BLX is a Spektrum Firma 2050Kv brushless motor, expertly matched to a Spektrum Firma 150A Smart V2 ESC with IC5 connectors, delivering punchy acceleration and smooth control. This advanced ESC also provides Smart telemetry data, enhancing the driving experience with real-time system monitoring. For robust construction, the BIG ROCK includes a reinforced 6061-T6 aluminum chassis with steel driveshafts and a metal drivetrain, making it ready for any high-speed bashing session.

The vehicle’s long, rugged crew cab body features ARRMA’s signature toughness with a clipless front mount system for easy access and a roll hoop for extra protection. Factory light buckets enable quick installation of optional LED lights, while the color options of Gunmetal, Red, and White offer a customizable look. The adjustable oil-filled shocks, paired with aluminum shock towers, ensure smooth travel over challenging terrain and keep the vented RAGNAROK V2 tires firmly grounded.

ARRMA includes the Spektrum SLT3 radio system for precise control, featuring a foam steering wheel and throttle-limiting function to make the BIG ROCK accessible to new and experienced RC drivers alike. The Spektrum SR315 receiver supports SLT and DSMR protocols for fast response rates and extended range, plus Smart telemetry compatibility when used in DSMR mode.

Ready for any terrain, the BIG ROCK 6S BLX RTR combines brawny construction, high-speed brushless power, and head-turning style in an impressive 1/7 scale monster truck designed to deliver unmatched performance.
