Description

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 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. In The Box Needed to Complete ARRMA BIG ROCK 223S BLX 4X4 Monster Truck RTR Features 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. 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. 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.) 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. 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. 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.

  • Great rc truck, does great in grass
Color: Green
Absolutely love this truck, got for my 6 or old B-day, he loves it, but it is advanced for him. Be ready to learn to replace A arms, but this thing is so fun, so fast, and very durable relatively speaking. Doesn't come with battery or charger, but at $320, it is shockingly fast

Great rc truck. I love the spektrum transmitter, tons of power, goes great in gravel and tall grass. Kids and I loved it.

  • Durable
Color: Black
Great truck. Probably the best in my collection of Arrmas,( Senton, Votrex, 6sV5 Kraton). Fast yet controllable, great air control too. ONLY complaint is run time on 5200mah batteries.. Upgraded to 8000mah and the time became acceptable. I’ve tumbled and bounced off a metal railing at speed without incurring any damage ( not suggested). Great truck. ... show more

  • Fun truck!
Color: Blue
This truck is fun. I have the 1st edition Big Rock also and the 2 trucks are great but this 223s version is so much better. 4 star because the first 10 minutes of driving this truck out of the box a bullet connector broke loose near the motor. Very fixable, but not the easiest connector to solder on if you are new to soldering. ... show more

  • This is the RC Truck you've been looking for
Color: Black
My 5 year old son and I absolutely love this truck . We've tried many other brands on Amazon and none of them seem to stand the test of time. they always died fairly quickly. But this one takes a beating and keeps on going. No cheap parts on this beast and it's super fast. If my son didn't have so much experience with all the other previous RC trucks...there's no way he would have been able to handle this one. If you're looking for an awesomely fun RC Truck? Look no further because you just found it. ... show more

  • Very Disappointing. Beware common issue.
Color: Blue
We ordered the Arrma Big Rock with high hopes reading many reviews of people that loved their truck. My son also has the Senton, which he loves but we can't keep tires on it.....pretty fast 3S set up. But the Big Rock, is absolutely the biggest pile of junk I have ever purchased since I started buying RTR/Kit RC cars 40 years ago. Brushless Spektrum motor straight locked up before the 2nd battery was run all the way through. In fact, maybe 5 minutes after the battery swap. I thought it was the rear diff or the center diff/trans but once I disassembled it, the motor was locked up completely. I had to use some fairly large pliers to get the motor broke free and then it just sounds like either the entire inside exploded or a bearing completely failed. After some research, this seems to be a fairly common issue with the new Spektrum brushless V3. I can not testify to the toughness of the rest of the truck since all the time playing was on flat grass and pavement and we haven't made it through even 2 batteries yet. Maybe the older ones are better and more durable, but beware of the newest ones with the Spektrum. Not sure if there is warranty or anything to cover the new motor, or if Arrma is aware this is an issue. I did see a video where Horizon hobby sent a guy a new motor (NOT Spektrum) under warranty and he did not have any issues after that. ... show more

  • Awesome truck!!
Color: Black
Amazing car,very sturdy and super rigid,my only complaint is I cant seem to get any battery pack to last over 10 minutes,just heard i need to cycle through a few charges for them to last longer so we will see. I do wish I would have got the quake or notorious because I really like popping wheelies and the big rock will do them but not as easy as my mini xrt (on 2s) or my deerc 8618 but still a great RC truck ... show more
