The ARRMA INFRACTION GROM 3S BLX 4X4 RTR brings the tyre-smoking attitude and drift-ready performance of the full-size INFRACTION into a compact 1/12 scale street basher.

Powered by a Spektrum Firma 4350Kv brushless motor and waterproof 40A brushless ESC, this compact all-road truck can reach speeds of over 80km/h when full Chaos Mode is unlocked using the included PowerKey. Its four-wheel-drive metal drivetrain puts the power down efficiently for hard launches, controlled drifts and high-speed street runs.

The PowerGuard system provides a more manageable Adrenaline Mode straight out of the box. Installing the included PowerKey unlocks the truck’s maximum 3S performance, allowing drivers to increase the available power as their experience and driving area permit.

Spektrum Dynamic Stability Control offers four selectable assistance settings to help keep the truck pointing in the intended direction. The amount of assistance can be adjusted from the transmitter or switched off completely, making the INFRACTION GROM suitable for progressing drivers as well as experienced street bashers.

This ST2 version is supplied in a Yellow/Black colour scheme and includes a Spektrum Smart 1300mAh 3S hardcase LiPo battery and S22 Mini USB-C charger.

PowerGuard and Chaos Mode

The PowerGuard system limits the truck to a more manageable performance level in Adrenaline Mode. This provides an easier introduction to the vehicle’s handling and speed.

When you are ready for maximum performance, install the included PowerKey to unlock Chaos Mode and the full output of the 3S brushless system. Always use full-power mode in a large, clear driving area away from people, traffic and obstacles.

Spektrum Dynamic Stability Control

Spektrum DSC automatically makes small steering corrections to improve directional stability during acceleration, drifting and driving over uneven surfaces.

Four selectable settings allow the level of assistance to be matched to the driver and surface. DSC can also be switched off completely for unrestricted manual control.

SmartFit Battery System

ARRMA’s SmartFit battery system securely holds the included hardcase battery without conventional hook-and-loop straps. The click-out design makes battery removal and replacement fast while maintaining secure retention during high-speed running.
