The ARRMA Big Rock is the perfect choice for those looking to experience the thrill of brushless monster truck action. This 1/10 scale, ready-to-run truck is packed with features, including a scale crew cab body, legendary ARRMA durability, and all-road dBoots Ragnarok tyres that let you tackle dirt tracks, trails, and even muddy courses with ease. As you gain experience, you can easily increase the speed potential to over 80 kph without needing expensive upgrades or a new vehicle.
The Big Rock is designed for versatility and ease of use. Start with a 2S LiPo battery for easy going 50+ kph speeds, then unleash the truck's full potential with a 3S battery and experience 80+ kph performance. The Spektrum SLT3 transmitter features a throttle limiting switch, allowing you to control the top speed until you're comfortable with the full power. Dynamic Stability Control (DSC) provides another layer of control, with four selectable modes that automatically correct steering input as needed.
The Big Rock is built for tough bashing. Heavy-duty, metal-gear differentials, a powerful Spektrum 3100Kv brushless motor, and an all-terrain independent suspension with oil-filled shocks ensure durability and performance on any surface. The strong composite chassis features extended height side guards to keep dirt and debris out, while the hidden clipless body retention system allows for quick and easy access for maintenance.
With its combination of affordability, scale realism, and impressive performance, the ARRMA Big Rock is the ultimate choice for those looking to experience the excitement of brushless monster truck bashing.

The 223S Series of vehicles offers the flexibility to run on both 2S and 3S LiPo batteries. Start with a 2S battery for powerful but manageable performance, then unleash pro-level speeds of 80+ km/h with a 3S battery when you're ready. The included radio allows you to limit the top speed to 50 or 75% until you're comfortable with the full 100% power potential.
The 223S BLX series features Spektrum's Dynamic Stability Control (DSC), making it ideal for new brushless drivers. With four selectable modes, DSC automatically applies steering corrections to improve control and safety on various surfaces. As your skills progress, you can turn off DSC and unleash the truck's full potential.
The 223S 4x4 range sports a durable composite chassis is built to withstand the punishment of extreme bashing. Its ventilated, hex comb design provides additional cooling and strength, while higher side guards provide maximum protection from dirt and debris.
Built to handle any terrain! The 223S BLX 4X4's heavy-duty transmission features oiled front, rear, and centre differentials. These metal gear differentials pair with the robust drivetrain components to withstand all the rigours of off-road driving, ensuring smooth and reliable power transfer to all four wheels.
The 223S 4X4's adjustable suspension allows you to fine-tune the ride height for optimal performance on any terrain. Oil-filled, coil-over shocks soak up bumps and jumps, while the independent suspension provides exceptional handling and control.

Verified buyerA very fun rc car to drive however, ive encountered alot of issues with this, when ever it gets into a small to medium size crash the drive shaft starts clogging or doesnt move, it just starts shaking the wheels in one place (Full throttle at 100%), i have to go there and lift the car and then start running again normally, it has alot of overheating issues too mainly in grass. When it works perfectly it is extremely fun but issues like this are annoying
