FAQ

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

Does the Red/Black ARA2315ST1 include a battery and charger? Yes. This version includes a Spektrum Smart 1300mAh 3S 30C hardcase LiPo battery and Spektrum S22 Mini USB-C charger.

Is anything else needed to run the truck? You will need a compatible USB-C power supply for the included charger and suitable LiPo-safe charging equipment. The truck, transmitter, LiPo battery, charger and transmitter AA batteries are included.

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

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

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

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

Is the INFRACTION GROM suitable for beginners? Adrenaline Mode and adjustable DSC make the truck more approachable, but it is still a high-performance brushless RC vehicle. Beginners should start in the lower-speed mode and drive in a large, clear area.

Can the truck drift? Yes. Its low-slung chassis, 4WD system and street-focused dBoots Hoons tyres are designed for pavement bashing, drifting and controlled slides.

Can I drive it on gravel or grass? The INFRACTION GROM is primarily designed for paved and other suitable firm surfaces. Rough ground, long grass and loose debris can reduce performance, increase tyre wear and place additional load on the drivetrain.

Is it four-wheel drive? Yes. It uses 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.

Are the tyres belted? Yes. The truck includes dBoots Hoons white compound belted tyres designed for high-speed street driving.

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

Can I use a different 3S battery? A replacement battery must meet the truck's voltage, connector, current and physical-fit requirements. The SmartFit system is designed around compatible battery dimensions and retention hardware.

Is the ESC waterproof? ARRMA describes the Spektrum SLT 2-in-1 ESC and receiver as waterproof. However, the truck should not be treated as suitable for submersion, and the battery and charger must be kept within their own operating limits.

How do I remove the body? The truck uses a quick-release clipless body system, allowing convenient access to the battery and chassis without removing traditional body clips.

Does the charger plug directly into a wall outlet? No. The included S22 Mini USB-C charger requires a compatible USB-C power supply, which is sold separately.

How long does the included battery last? Runtime varies with speed mode, driving style, surface, temperature and battery condition. High-speed Chaos Mode driving generally places greater demand on the battery.

Are replacement parts available? ARRMA provides replacement parts and exploded-view support for the INFRACTION GROM platform. Always match replacement components to the exact ARA2315ST1 version.
