The ARRMA INFRACTION GROM 3S BLX 4X4 RTR brings the tyre-smoking attitude, controlled drifting and high-speed performance of the full-size INFRACTION into a compact 1/12 scale package.

Powered by a Spektrum Firma 4350Kv brushless motor and waterproof 40A brushless ESC, this compact all-road truck can reach speeds exceeding 80km/h when Chaos Mode is unlocked. Its enclosed metal four-wheel-drive system and sealed centre differential distribute power across all four wheels for hard launches, controllable drifts and high-speed street runs.

ARRMA’s PowerGuard speed-management system provides two distinct performance levels. Adrenaline Mode limits the speed to a more manageable 48km/h-plus, helping drivers become familiar with the truck. Installing the included PowerKey unlocks Chaos Mode and the full performance of the 3S brushless system.

Spektrum Dynamic Stability Control provides four selectable settings—Off, Low, Medium and High. The system makes automatic steering corrections to improve stability during acceleration and drifting while allowing the driver to select the preferred level of assistance.

This ARA2315T1 version features a Blue/Red colour scheme. A suitable 3S hardcase LiPo battery and compatible charger are required separately.

PowerGuard and PowerKey

PowerGuard allows the performance to be matched to the driver and available space.

Adrenaline Mode provides a more controlled speed of over 48km/h, making it easier to learn the vehicle’s handling characteristics. Installing the included PowerKey unlocks Chaos Mode and speeds exceeding 80km/h under suitable conditions.

Spektrum Dynamic Stability Control

Spektrum DSC automatically makes small steering corrections to help maintain the intended direction during acceleration, drifting and high-speed driving.

The SLT2 transmitter offers four selectable DSC modes:

• Off – No steering assistance

• Low – Minimal assistance

• Medium – Increased stability

• High – Maximum available assistance

SmartFit Battery System

The SmartFit system uses a precisely sized click-in hardcase battery rather than conventional hook-and-loop straps. This provides secure retention and allows fast battery removal.

The recommended Spektrum 1300mAh 3S SmartFit battery fits directly into the factory system. An optional battery strap is required when using some alternative batteries.
