ARRMA 1/10 BIG ROCK 223S

The 1/10 scale, ready-to-run BIG ROCK 223S BLX 4X4 delivers everything you want in a first brushless monster truck. Its scale crew cab body brings authentic street style, while legendary ARRMA durability and all-road dBoots RAGNAROK tyres expand your bashing territory to include dirt tracks, trails, and even muddy courses. It also represents outstanding value — as your experience grows, you can easily increase the speed potential to over 80 km/h without buying upgrades or changing vehicles.

ARRMA developed the 223S series specifically for newcomers to brushless bashing who want to progress from 2S to 3S power without needing expensive option parts or purchasing a completely new basher. On a 2S LiPo battery, the BIG ROCK 223S BLX 4X4 reaches speeds of over 56 km/h, matching or even exceeding the performance of other manufacturers’ 2S bashers. When you’re ready for more, simply switch to a 3S battery and unleash the monster truck’s full 80+ km/h potential.

You decide how fast your BIG ROCK 223S BLX 4X4 goes based on your battery choice and the throttle limiting setting on the Spektrum SLT3 transmitter. Throttle limiting automatically caps the top speed at a level you’re comfortable with until you’re ready for maximum performance. With the switch set to 50% or 75%, you’ll never feel out of control, making the transition from 2S to 3S speeds smooth and confidence-inspiring.

Dynamic Stability Control (DSC), built into the monster truck’s Spektrum electronics, offers another major advantage — and not just for beginners. With four selectable modes, DSC automatically corrects steering input when needed to improve control and confidence on any surface. When you prefer full manual control, simply switch DSC off and rely entirely on your driving skills.

Factory-assembled heavy-duty metal gear differentials transfer power from the Spektrum 3100Kv brushless motor to all four wheels for dependable bashing on dirt, gravel, or short grass. The protected power system, combined with the all-terrain independent suspension and oil-filled shocks, absorbs bumps with ease. Build ramps or shape dirt mounds and enjoy big air without worry. Extended-height side guards on the strong composite chassis, along with the close-fitting body, help keep dirt and debris out of the chassis tub. When maintenance is required, the hidden clipless body retention system provides quick and easy access.

The ARRMA BIG ROCK 223S BLX 4X4 comes equipped with high-quality, factory-installed Spektrum electronics, including an 80A waterproof ESC/receiver and a metal-geared S662 waterproof servo. It’s the ideal combination of affordability, scale realism, and 2S to 3S performance potential. Simply add your preferred battery and charger, and take your monster truck bashing to the next level.
