If you're starting in the world of brushless monster trucks, the BIG ROCK 223S BLX 4X4 is a perfect choice. With a lot of brushless bashers, you have to choose between 2S or 3S. When you get off-road with the BIG ROCK 223S BLX 4X4 you have the option of choosing either LiPo choices. Plugging in a 2S LiPo will give you impressive performance with top speeds exceeding 56 km/h, which is enough to beat most 2S bashers on the market. If you're feeling like you have the need for speed you can plug in a 3S LiPo and hit speeds of 80+ km/h! If you want to keep things under control, or, if the kids are going to have a turn there is a speed limiter switch on the Spektrum SLT3 radio included that you can engage that will reduce the power output to 50% or 75%. Ordinarily, you would probably need to upgrade your internals or switch up to a new car once you had mastered the 2S-powered basher but not with the BIG ROCK. You get the option of both 2S or 3S LiPos from the get-go.

That covers off the speed you have at your disposal but you also have to consider the way the BIG ROCK 223S BLX 4X4 looks. ARRMA have captured the rugged truck style perfectly in the BIG ROCK with scale details like folding wing mirrors just the start of the attention placed on the realism. When it comes to ARRMA you know you are getting toughness, and with dBoots RAGNAROK tyres fitted it means you can take your BIG ROCK confidently into just about any terrain.
Dynamic Stability Control (DSC)
The Spektrum electronics built into the BIG ROCK 223S BLX 4X4 monster truck are equipped with Dynamic Stability Control (DSC) to give you a distinct driving advantage. There are four different DSC modes to select from that will automatically correct the driver's steering input to improve your confidence, control and safety on a range of different surfaces. Once you feel confident enough you can turn off DSC and fly down the trails by the seat of your pants.
Power from the 3100Kv Spektrum brushless motor is transferred to the factory-assembled and installed, heavy-duty, metal gear differentials that turn your dBoots RAGNAROK tyres fitted to huge multi-spoke wheels at a rate that will easily handle bashing on gravel, dirt, short grass and most surfaces. Grabbing some air of a ramp or dirt mounds is no problem as the oil-filled shocks and independent suspension can handle the landings that you'll put your BIG ROCK 223S BLX 4X4 monster truck through. You can customise your ride height to suit the trail surfaces which will lessen the effect of uneven ground and give you more terrain clearance. The close-fitting body and the extended height side guards on your powerful composite chassis will work to keep dirt and stones out of the chassis tub. If you need to ‘tinker under the bonnet’ to perform any maintenance tasks you will get quick and easy chassis access using the hidden clipless body retention system.

Waterproof Electronics for Worry-Free Bashing
If it's raining and wet outside that's not going to worry the BIG ROCK 223S BLX 4X4 monster truck. The S662 Spektrum digital metal geared steering servo and the 80A SLT Spektrum 2S/3S waterproof 2-in-1 receiver and ESC are both waterproof.

Detailed street truck body
The styling on the BIG ROCK 223S BLX 4X4 monster truck is rugged by design and while it will look great to those you fly by at 60 k's an hour it looks even better when you take a closer inspection.
