Overview
Built on the proven 6S BLX platform and supersized to 1/7 scale, the ready-to-run BIG ROCK™ 6S BLX 4×4 blasts like only a large-scale ARRMA® RC monster truck can — especially when amped up with Spektrum™ brushless power and topped with an eye-catching crew cab body. Featuring loads of realistic scale details and “stealth” black-anodized aluminum parts, the ARRMA BIG ROCK 6S BLX is big, fierce, fast, and tough.

Its 6S LiPo capable brushless power system includes a highly efficient Spektrum Firma™ 2050Kv brushless motor that’s perfectly matched to a Spektrum Firma 150A Smart V2 waterproof ESC with IC5® connectors. The ESC has been updated to deliver more punch and an improved driving feel. Install the supplied, optional speed pinion, and the BIG ROCK 6S BLX can reach incredible 65+ mph speeds in optimum driving conditions.

From the reinforced, black-anodized 6061-T6 aluminum chassis to the independent suspension with adjustable, aluminum-bodied, oil-filled shocks, the characteristically durable ARRMA design lets you fearlessly tackle all terrain and all conditions. The metal drivetrain, steel driveshafts, and metal-geared Spektrum S665 digital steering servo all work together to bring out the full bashing potential of 6S brushless power.

The BIG ROCK 6S BLX RTR’s long, scale body marks the epitome of rugged truck style. An easy-to-use, clipless front body mount system preserves its incredibly detailed scale looks, and an integrated roll hoop and bed add more ARRMA toughness. Massive, vented dBoots® RAGNAROK™ V2 tires on five-spoke wheels complement the scale looks — and the tires’ aggressive tread gets the grip you need for high speeds and easy handling over a wide variety of surfaces.

Assembled, finished, and complete with high-quality Spektrum SLT3™ radio system, the ARRMA BIG ROCK 6S BLX RTR requires only your choice of the recommended LiPo batteries and charger before delivering big brushless performance with incomparable scale style.

It features a black-anodized aluminum chassis with strong composite side guards, center body support and brace for maximum durability. The heavy-duty drivetrain includes all-metal diff outdrives and gearbox internals. Durable steel driveshafts are used throughout.

SCALE CREW CAB BODY & OPTIONAL LIGHT SET
The BIG ROCK™ 6S BLX RTR’s long, scale Crew Cab body marks the epitome of rugged truck style. The clipless front body mount system is easy to use and remains concealed to preserve the detailed scale looks. Three factory-finished body color choices are available — Gunmetal, Red, and White. Factory light buckets make installation of the optional LED light set (ARA480075) quick and easy.

dBOOTS® RAGNAROK™ V2 TIRES
The tough, off-road tread pattern of the vented dBoots RAGNAROK V2 tires provides an aggressive grip for high speeds and easy handling on a wide variety of surfaces. The tires are mounted on stylish five-spoke wheels that complement the scale truck looks.

ADJUSTABLE OIL-FILLED SHOCKS
The adjustable, oil-filled shocks have black-anodized aluminum bodies and are mounted on black-anodized aluminum front and rear shock towers. The shocks keep the tires firmly planted for high traction and provide smooth travel over rough off-road terrain.

SPEKTRUM™ SLT3™ 2.4GHz 3-CHANNEL TRANSMITTER
The included Spektrum SLT3 transmitter is ergonomically designed for fatigue-free bashing and has a foam wheel for precise fingertip control. Using the throttle limiting function, new RC drivers can limit top speed to 50% or 75% of the truck’s full potential until they’re ready to unleash it all.

SPEKTRUM™ SR315 3-CHANNEL DUAL PROTOCOL RECEIVER
Compatible with SLT™ and DSMR® protocols, the included Spektrum SR315 3-channel receiver offers outstanding range and fast response rate. It’s also Smart telemetry compatible (in DSMR mode and using the Spektrum Dashboard app).

SPEKTRUM™ S665 WATERPROOF DIGITAL STEERING SERVO
With its strong metal gears and waterproof design, the included Spektrum S665 digital steering servo endures punishing off-road action through any surface conditions while delivering impressive torque (20kg-cm / 277.75 oz-in @ 7.4V) for confident control.

SPEKTRUM™ BRUSHLESS POWER SYSTEM
The BIG ROCK™ 6S BLX RTR’s 6S-capable brushless power system consists of a highly efficient Spektrum Firma™ 2050Kv brushless motor matched perfectly to an updated Spektrum Firma 150A Smart V2 waterproof ESC with IC5® connectors (also compatible with EC5™ connectors). In addition to offering Smart telemetry capabilities, the ESC has a new look, more punch, and improved driving feel.
