1/10 Big Rock 223S 4x4 Ready to Run (Black) (ARA4312V4T1)

ARRMA BIG ROCK 223S BLX 4X4 Monster Truck RTR is a 1/10-scale, ready-to-run brushless monster truck designed for new drivers who want a platform that grows with them. It features a scale crew-cab body and dBoots Ragnarok all-terrain tires for grip on dirt, gravel, and trails. Ready to roll out of the box—just add a battery and charger—and with throttle-limiting on the included Spektrum radio you can limit top speed to 50% or 75% as you learn, hitting around 35+ mph on 2S and more than 50 mph on 3S. A Dynamic Stability Control system provides automatic steering corrections to help you stay in control as you build confidence.

Inside, the truck relies on waterproof Spektrum electronics, including an 80A ESC/receiver and a S662 metal-geared digital servo powered by a 3100Kv brushless motor and a 35mm cooling fan. The power moves through heavy-duty metal gears to all four wheels via a center differential, while an independent suspension with adjustable oil-filled shocks absorbs bumps for smooth landings. A hidden clipless body retention system keeps the scale body secure during hard bashing, and the rugged chassis and drivetrain are ready for continued use and upgrades as skills grow.
