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

ARRMA developed the 223S series especially for brushless bashing newcomers who want to grow from 2S to 3S power without needing expensive option parts or buying a whole new basher. On a 2S LiPo, the BIG ROCK 223S BLX 4X4 reaches 35+ mph top speeds. That speed matches or even beats the best that other manufacturers’ 2S bashers can do. Whenever you’re ready, switch to a 3S battery. Now you can unleash this monster truck’s full 50+ mph potential!

You control how fast your BIG ROCK 223S BLX 4X4 can go based on your battery choice and where you set the Spektrum SLT3 transmitter’s throttle limiting switch. Throttle limiting automatically restricts top speed to a level you prefer until you’re ready for it all. With the switch set to 50% or 75%, you’ll never worry about going faster than you can safely control. You’ll make the transition from 2S to 3S speeds with absolute confidence.

The Dynamic Stability Control (DSC) built into the monster truck’s Spektrum electronics offers another big advantage, and not just for brushless newcomers. With four selectable modes, DSC can automatically correct steering input as needed to improve your control and confidence on any surface. Just turn off the DSC whenever you want to rely only on the skills you’ve learned.

Factory assembled and installed, the 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 entire power system is well-protected and the all-terrain independent suspension and oil-filled shocks soak up bumps. Set up ramps or build some dirt mounds and launch your truck into the air! Extended height side guards on the strong composite chassis combine with the close-fitting body to keep dirt and debris out of the chassis tub. When maintenance is needed, the hidden clipless body retention system allows quick, easy chassis access.

The ARRMA BIG ROCK 223S BLX 4X4 comes complete with installed, high-quality Spektrum electronics, including an 80A waterproof ESC/receiver and metal geared S662 waterproof servo. It’s the perfect mix 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.

ARRMA BIG ROCK 223S BLX 4X4 Monster Truck RTR Features

2S & 3S READY

Don’t compromise your early success or your future growth by choosing a brushless basher that’s strictly 2S or 3S capable. With the BIG ROCK 223S BLX 4X4, you get both in one monster truck. Start with a 2S LiPo for powerful performance that can match or beat the best that other manufacturers’ 2S bashers can do. When ready, install a 3S battery for amped-up, pro-level 50+ mph bashing! The included SLT3 radio can automatically limit top speed to a comfortable level until you’re ready to unleash it all.

DYNAMIC STABILITY CONTROL (DSC)

Dynamic Stability Control (DSC) built into the Spektrum electronics gives newcomers another edge while learning how to control high-speed brushless power. With four selectable modes, DSC will automatically apply steering corrections to improve your control, confidence, and safety, no matter what surface you’re driving on. As you gain experience, just turn off the DSC and use the skills you’ve learned.

SPEKTRUM 2.4GHz SLT3 TRANSMITTER

The high-quality Spektrum SLT3 3-channel transmitter has features designed to help all drivers succeed. Throttle Limiting is just one example. Whether you’re using 2S or 3S power, Throttle Limiting enables you to learn control skills safely by limiting the truck’s maximum available speed to 50% or 75% until you’re ready for it all. Four AA batteries are included.

SPEKTRUM ELECTRONICS

Bash without worry, even in wet conditions. Both the Spektrum SLT 80A 2-in-1 brushless 2S/3S ESC and receiver unit and the Spektrum S662 metal-geared digital steering servo are waterproof. (For details on waterproof standards, refer to the BIG ROCK 223S BLX 4X4 instruction manual.)

SUPER TOUGH TRANSMISSION

Factory assembled and installed, the heavy-duty, metal gear differentials send power from the Spektrum 3100Kv brushless motor to all four wheels for blasting through challenging terrain. The entire power system is well-protected for dependable performance on all terrain.

ADJUSTABLE SUSPENSION

The all-terrain independent suspension and oil-filled, coilover shocks soak up bumps. If your bashing takes you over uneven surfaces, you can adjust the ride height to increase ground clearance.

DETAILED MONSTER TRUCK BODY

The epitome of rugged truck style, the BIG ROCK 223S BLX 4X4 monster truck body is securely held in place by a hidden, clipless body retention system that’s easy to use and preserves the scale looks. Details such as folding wing mirrors add to the exciting realism. The body is available in three factory-finished color scheme options.
