Compact dimensions, powerful acceleration and controlled drifts: the Arrma Infraction Grom 3S BLX brings serious street-bashing performance to a 1/12 scale platform. Its low chassis, durable metal 4WD drivetrain and asphalt-focused dBoots Hoons tyres are designed for fast runs on suitable parking lots, driveways and paved areas.
The RC car comes fully assembled with installed brushless electronics, a steering servo and a Spektrum SLT2 transmitter. This version is supplied without a driving battery or charger, allowing you to choose a suitable 3S LiPo and charger or use compatible equipment you already own.
With a suitable 3S LiPo battery, the Spektrum Firma 4350 Kv brushless motor delivers speeds of over 45 km/h in Adrenaline Mode. Insert 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 battery, 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. Switch the system off for full manual steering control.
The enclosed metal 4X4 drivetrain helps keep dirt away from the drive components and provides reliable power transmission. A sealed centre differential with a metal spur gear and aluminium 12 mm wheel hexes complement the durable construction. Front and rear differentials remain easily accessible for maintenance.
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 expansion at high rotational speeds and maintain their shape.
The clipless body can be removed without conventional body clips for quick access to the chassis. The SmartFit battery system secures a matching SmartFit battery with a click-in mechanism and connects it through the integrated battery connection. The optional ARA-1418 battery strap allows the use of other suitable batteries; battery dimensions and connector must match the vehicle.
