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.

Clipless Body System

The Big Rock 223S BLX 4X4's detailed monster truck body captures the rugged style of full-size trucks, with features like folding wing mirrors adding to the realism. The clipless body retention system provides a secure hold while preserving the scale looks.

2S & 3S Ready

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.

Dynamic Stability Control (DSC)

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.
