Drift, accelerate and power through corners with four-wheel drive: the Arrma Infraction Grom 3S BLX brings powerful street-bashing performance to a compact 1/12 scale platform. Its low chassis, durable metal drivetrain and asphalt-focused dBoots Hoons tyres provide the foundations for fast runs and controlled drifts on suitable parking lots, driveways and paved areas.
This fully assembled Ready-to-Run RC car includes a Spektrum SLT2 transmitter, a Spektrum Smart 3S LiPo battery and a matching USB-C charger. Its compact size makes it easy to transport to your next suitable driving location.
The Spektrum Firma 4350 Kv brushless motor delivers speeds of over 45 km/h in Adrenaline Mode. Use the included PowerKey to unlock Chaos Mode and access the full performance potential for speeds of over 80 km/h. Actual top speed depends on the surface and driving conditions.
Spektrum Dynamic Stability Control supports you with automatic steering corrections. Four selectable settings – Off, Low, Medium and High – let you adjust the assistance to the available grip and your driving experience. Start with more support, reduce it as your confidence grows or switch it off for full manual steering control.
The enclosed metal 4X4 drivetrain features a sealed centre differential and a metal spur gear for reliable power transmission. Its enclosed design helps keep dirt away from the drive components, while the front and rear differentials remain easily accessible for maintenance. Aluminium 12 mm wheel hexes and a durable composite chassis complete the robust construction.
Independent double-wishbone suspension and oil-filled shocks help maintain control on uneven asphalt. Adjustable steering links allow you to fine-tune the handling. The dBoots Hoons White Compound street tyres feature belted construction to limit tyre expansion at high rotational speeds and maintain their shape.
Battery changes are quick and straightforward. The clipless body can be removed without conventional body clips, providing direct access to the chassis. The SmartFit system secures the matching battery with a click-in mechanism. An integrated battery connection and strap-free installation make fitting and removing the battery easy.
