1/10 Big Rock 223S 4x4 Ready to Run (Blue) (ARA4312V4T3)

ARRMA BIG ROCK 223S BLX 4X4 Monster Truck RTR is a 1/10-scale, ready-to-run brushless monster truck designed for rugged bashing on dirt, gravel, and trails. It grows with you—from about 35 mph on 2S LiPo to 50 mph and beyond on 3S—thanks to throttle limiting on the included Spektrum radio and Dynamic Stability Control that helps you stay in command as you learn.

Under the hood, a tough Spektrum system powers a 3100Kv brushless motor through an 80A waterproof ESC/receiver to all four wheels via a heavy‑duty metal‑geared drivetrain. The all‑terrain, independent suspension with adjustable oil‑filled shocks cushions rough surfaces, while dBoots Ragnarok tires and a durable composite chassis provide lasting grip and strength. A hidden clipless body retention system preserves the scale look, and the model ships factory‑assembled—just add a battery and charger to start bashing.
