Product Information

Ready to run and fully upsized to 1/7th scale, the BIG ROCK™ 6S BLX 4x4 has been built on ARRMA's proven 6S BLX platform and delivers...big time! The realistic scale details on the BIG ROCK mean it won't be just the blistering speed that turns heads. Eye-catching crew cab body in three different factory-finished colours with a range of scale details and black anodized 'stealth’ aluminium parts set this monster truck apart from the rest. 

Monster power with the brushless Big Rock

Arrma Big Rock 6S

The highly efficient brushless power system in the ARRMA BIG ROCK™ 6S BLX 4x4 is a 6S capable 2050Kv Spektrum Firma motor with 150A Smart V2 Spektrum Firma waterproof ESC with IC5 connectors (also compatible with EC5 connectors). The ESC gives you an improved driving feel and packs more punch along with having a new look and Smart telemetry capabilities. If you want to push your ARRMA BIG ROCK™ 6S BLX 4x4 to max speed, just install the optional speed pinion that is supplied and you'll be blasting at 105 km/h plus if driving conditions are optimum.

Big Rock 6S BLX 4x4: Dominating in 1/7th scale

The chassis on the ARRMA BIG ROCK™ 6S BLX 4x4 is made from black anodized reinforced 6061-T6 aluminium and in conjunction with the aluminium, adjustable, oil-filled shocks you can fearlessly tackle just about any surface in all conditions. Steel driveshafts and a heavy-duty drivetrain combine well with the S665 metal-geared digital Spektrum steering servo which allows you to harness even more of the 6S brushless power on offer. 

RC Monster Truck

The long-scale body on the ARRMA BIG ROCK™ 6S BLX 4x4 embodies the rugged monster truck style. You also have the option of three factory-finished body colour choices – Red, White and Gunmetal. A clipless front body mount system that is easy to use helps preserve the scale looks on the BIG ROCK and more toughness is added with an integrated roll hoop and bed. Complementing the scale body look are huge, vented dBoots RAGNAROK V2 tyres on five-spoke wheels with strengthened hubs. The tread on these tyres is suited to both advanced handling on a number of different surfaces as well as high-speed runs.  

Reliable Spektrum control and connectivity

Arrma 6S BLX

Ergonomically designed for fatigue-free bashing the SLT3 Spektrum transmitter that comes with you ARRMA BIG ROCK™ 6S BLX 4x4 has a foal wheel for precise fingertip control. The throttle limiting function limits the speed to 50% or 75% of the truck's full speed if you're a beginner or if you're a parent with children who are into RC monster trucks. It's not going to take long with this bad boy in the garage. With both DSMR and SLT compatibility, the SR315 Spektrum 3-channel receiver that comes with your BIG ROCK gives you superb range and a brilliant response rate. If you are using this receiver in DSMR mode and you've downloaded the Spektrum Dashboard app you have access to Smart telemetry data straight to your transmitter. With a waterproof design and strong metal gears, the S655 digital Spektrum steering servo can endure plenty of off-road punishment on a wide range of surfaces. This servo also provides huge torque (20kg-cm/277.75oz-inches @ 7.4V) giving you complete confidence in the vehicle's control. 

Assembled and finished straight out of the box your ARRMA BIG ROCK™ 6S BLX 4x4 on needs a charger and your fully charged LiPo of choice and then you are going to be bashing with the best of them!
