ARRMA INFRACTION GROM 3S BLX 1/12 4WD RTR Brushless Street Bash Truck White/Blue ARA2315T1

Experience full-throttle street bashing in a compact package with the ARRMA INFRACTION GROM 3S BLX 1/12 4WD RTR Brushless Street Bash Truck, ARA2315T1. Featuring an aggressive multi-colour street-truck body, 3S brushless power and an enclosed metal 4WD drivetrain, this small-scale INFRACTION is built for pavement drifting, high-speed runs and all-road RC excitement.

A Spektrum Firma 4350Kv brushless motor and Spektrum SLT 2-in-1 40A brushless ESC/receiver provide the performance behind ARRMA's advertised 50+ mph capability. The PowerGuard system offers 30+ mph Adrenaline Mode for more manageable driving, while the included PowerKey unlocks full-performance Chaos Mode.

Spektrum Dynamic Stability Control (DSC) provides four selectable levels of steering assistance to help manage slides and high-speed manoeuvres. The low-slung composite chassis, oil-filled shocks, sealed centre differential and dBoots Hoons white compound belted tyres deliver a street-focused combination of handling, traction and durability.

The quick-release clipless body provides convenient access to the chassis, while the SmartFit click-out battery system makes compatible battery changes quick and secure. The included Spektrum SLT2 2.4GHz transmitter, installed electronics and four AA transmitter batteries complete the RTR vehicle package.

Battery and charger sold separately. This ARA2315T1 version requires a compatible 3S LiPo battery with IC2 connection, a suitable LiPo charger and a LiPo-safe charging bag before driving.

FAQ

Does the ARRMA INFRACTION GROM ARA2315T1 include a battery? No. This version is supplied without a vehicle battery. A compatible 3S LiPo battery must be purchased separately.

Is a charger included? No. A suitable LiPo battery charger is sold separately.

Why is this model called RTR if the battery is not included? Ready-to-Run means the vehicle is assembled and includes the installed electronics and radio system. Some RTR models still require a vehicle battery and charger.

What battery does it need? It requires a compatible 3S LiPo battery with a suitable IC2 connection, discharge capability and physical dimensions.

Will any 3S LiPo battery fit? No. Check the battery's dimensions, connector, polarity and discharge capability. The SmartFit mounting system is designed for compatible battery sizes, while an optional strap supports certain alternative packs.

What is the maximum battery size? The standard battery tray measures approximately 100 x 34 x 20.3mm. With the optional ARA-1418 battery strap, ARRMA lists maximum dimensions of approximately 112 x 34 x 22.5mm.

How fast is the INFRACTION GROM 3S BLX? ARRMA advertises 30+ mph in Adrenaline Mode and 50+ mph in Chaos Mode with suitable 3S power.

What does the PowerKey do? The included PowerKey unlocks Chaos Mode and the vehicle's full advertised performance capability.

What is Spektrum Dynamic Stability Control? DSC is an electronic steering-assistance system that can apply automatic corrections to help drivers manage slides and drifting.

Can I turn DSC off? Yes. DSC has four settings: Off, Low, Medium and High.

Is the INFRACTION GROM suitable for beginners? Adrenaline Mode and DSC can make the truck more manageable, but it remains a high-performance brushless vehicle. New drivers should start at lower speeds in a large, clear area.

Can this truck drift? Yes. The low-slung chassis, 4WD system and belted dBoots Hoons tyres are designed for pavement drifting and street bashing.

Can I use it on grass or gravel? It is primarily designed for pavement and other suitable firm surfaces. Long grass and rough terrain can increase drivetrain load and reduce performance.

Does it have a centre differential? Yes. It has a sealed centre differential with a metal spur gear, plus front and rear differentials.

What tyres are included? The truck uses dBoots Hoons white compound belted street tyres.

Does it have an IC2 connector? Yes. The ESC uses a Spektrum IC2 battery connection. IC2 and EC2 should not be treated as directly interchangeable.

Does the truck come with a transmitter? Yes. The package includes a Spektrum SLT2 2.4GHz transmitter with DSC controls and four AA transmitter batteries.

Is the ESC waterproof? ARRMA describes the Spektrum SLT 2-in-1 ESC and receiver as waterproof. This does not make the entire vehicle suitable for submersion. Follow the manufacturer's wet-condition maintenance instructions.

How do I remove the body? The quick-release clipless body system allows convenient chassis and battery access without traditional body clips.

Are replacement parts available? ARRMA provides model-specific spare parts and support. Check the exact ARA2315T1 part number when ordering replacement components.
