ARRMA 1/10 Blue BIG ROCK 4X4 223S BLX Brushless RTR RC Truck with DSC - Battery & Charger Required ARA4312V4T3

The 1/10 scale, ready-to-run BIG ROCK 223S BLX 4X4 has everything you’re looking for in a first brushless monster truck. Its scale crew cab body delivers impressive street style, while legendary ARRMA durability and all-road dBoots RAGNAROK tires expand your bashing territory to include dirt tracks, trails, and muddy courses. It’s an exceptional value — and as you gain experience, you can easily increase speed potential to over 50 mph without buying upgrades or changing vehicles.

ARRMA developed the 223S series specifically for brushless bashing newcomers who want to grow from 2S to 3S power without expensive option parts or purchasing a new basher. On a 2S LiPo, the BIG ROCK 223S BLX 4X4 reaches 35+ mph top speeds, matching or exceeding the performance of many competing 2S bashers. When you’re ready, switch to a 3S battery and unleash this monster truck’s full 50+ mph potential.

You control how fast the BIG ROCK 223S BLX 4X4 can go based on battery choice and the Spektrum SLT3 transmitter’s throttle-limiting switch. Throttle limiting automatically restricts top speed to a level you choose until you’re ready for full performance. With the switch set to 50% or 75%, you can build confidence without worrying about exceeding your control limits, making the transition from 2S to 3S speeds smooth and predictable.

The Dynamic Stability Control (DSC) built into the truck’s Spektrum electronics offers another major advantage, not just for brushless newcomers. With four selectable modes, DSC automatically corrects steering input as needed to improve control and confidence on any surface. When you prefer to rely solely on your driving skills, DSC can be turned off completely.

Factory-assembled heavy-duty metal-gear differentials send power from the Spektrum 3100Kv brushless motor to all four wheels for worry-free bashing on dirt, gravel, or short grass. The power system is well protected, while the independent suspension and oil-filled shocks absorb bumps and landings. Extended-height side guards on the strong composite chassis, combined 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 chassis access.

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