FAQ

How fast is the ARRMA INFRACTION GROM 3S BLX? ARRMA advertises 30+ mph in Adrenaline Mode and 50+ mph in Chaos Mode, which is unlocked using the included PowerKey. Actual performance depends on driving conditions.

Does the Yellow/Black ARA2315ST2 include a battery and charger? Yes. It includes one Spektrum Smart 1300mAh 3S 30C hardcase LiPo battery with IC2 connector and a Spektrum S22 Mini USB-C charger.

What else do I need to get started? A compatible USB-C power supply and LiPo-safe charging bag are required separately. The truck, transmitter, battery, charger and four AA transmitter batteries are included.

What is PowerGuard? PowerGuard is ARRMA's speed-management system, providing a lower-speed Adrenaline Mode and an unlockable full-performance Chaos Mode.

What does the included PowerKey do? The PowerKey unlocks Chaos Mode, allowing access to the truck's advertised 50+ mph performance capability.

What is Spektrum DSC? Dynamic Stability Control automatically applies steering corrections to help manage drifting, slides and other driving manoeuvres.

Can DSC be turned off? Yes. The system offers Off, Low, Medium and High settings, allowing drivers to choose their preferred level of steering assistance.

Is the INFRACTION GROM suitable for beginners? Adrenaline Mode and DSC can help new drivers build confidence, but the truck is still a powerful brushless model. Start in the lower-speed setting and use a large, clear driving area.

Can this RC truck drift? Yes. The INFRACTION GROM is designed for street-focused driving, with a low-slung chassis, four-wheel drive and belted dBoots Hoons tyres.

Can I use it on grass or gravel? It is primarily designed for pavement and suitable firm surfaces. Long grass, rough gravel and loose debris may reduce performance and increase wear.

Does it have four-wheel drive? Yes. The truck features an enclosed metal 4WD drivetrain with front, centre and rear differentials.

Does it have a centre differential? Yes. The sealed centre differential includes a metal spur gear.

What tyres are fitted? It includes dBoots Hoons white compound belted tyres for street driving, drifting and high-speed stability.

What battery connector does it use? The included battery and ESC use Spektrum IC2 connections. IC2 is not directly interchangeable with EC2.

Can I use another 3S battery? A replacement battery must meet the required voltage, connector, discharge and physical-fit specifications. The SmartFit system is designed for compatible battery dimensions and connections.

Is the truck waterproof? The Spektrum SLT 2-in-1 ESC and receiver are described as waterproof. However, this does not mean the complete vehicle or battery can be submerged. Follow the manufacturer's wet-condition maintenance instructions.

How do I remove the body? The quick-release clipless system allows easy body removal for battery changes and chassis access.

Does the included charger need a wall adapter? Yes. The S22 Mini USB-C charger requires a compatible USB-C power supply, sold separately.

How long will the included battery last? Runtime varies with speed mode, throttle use, surface conditions, temperature and battery condition. High-speed driving generally consumes battery energy more quickly.

Are replacement parts available? ARRMA provides model-specific spare parts and exploded-view support. Match replacement components to the exact ARA2315ST2 model.
