ARRMA BIG ROCK 223S BLX 4X4 Monster Truck RTR

Looking for your first brushless, ready-to-run monster truck with impressive performance? The BIG ROCK 223S BLX 4X4 from ARRMA is exactly what you need! Its aggressive crew cab design and dBoots RAGNAROK tires give it a fierce look on the road and unstoppable off-road capability.

Evolving Performance – Seamlessly Upgrade from 2S to 3S Power

ARRMA designed the 223S series specifically for speed enthusiasts who want to progress without switching vehicles or investing in costly upgrades. With a 2S LiPo battery, the BIG ROCK 223S BLX 4X4 reaches 35+ mph (56 km/h), outperforming many competitors.

Stay in Control with Safety Features

With the Spektrum SLT3 transmitter and its built-in throttle limiter, you control your speed based on your skill level. Set it to 50% or 75% for a progressive learning curve and maximum control. This ensures a smooth transition from beginner to pro.

Additionally, the integrated Dynamic Stability Control (DSC) automatically adjusts steering input for improved handling on any terrain. Choose from four modes or disable it entirely when you’re ready to test your skills at full power.

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.
