Arrma MOJAVE GROM MEGA 380 Brushed 4X4 Small Scale Desert Truck RTR with Battery & Charger

Overview

The ARRMA MOJAVE GROM is a compact desert racing truck designed to deliver serious off-road performance in a small and highly portable RC platform. Inspired by the larger ARRMA Mojave desert trucks, this scaled-down version keeps the aggressive styling, wide stance, and rugged construction that make desert trucks so exciting to drive.

At 1/16 scale, the MOJAVE GROM is small enough to drive in parks, backyards, or driveways while still offering the durability and control expected from an ARRMA vehicle. It is built around a strong composite chassis and a 4WD drivetrain, which provides excellent traction on loose surfaces such as dirt, gravel, or sand.

The truck is powered by the ARRMA MEGA 380 brushed motor, which delivers reliable power and smooth throttle response. This type of motor is well suited for both beginners and casual RC drivers because it offers consistent performance and simple maintenance.

One of the biggest advantages of the MOJAVE GROM is its ready-to-run package. The vehicle arrives fully assembled and includes everything needed to start driving. The box contains the truck, a Spektrum SLT2 2.4GHz transmitter, a Spektrum Smart 2S LiPo battery, and a USB-C charger. This means new drivers can start enjoying the hobby almost immediately.

The MOJAVE GROM is designed with durability in mind. The drivetrain uses metal gears and enclosed components, helping protect critical parts from dirt and debris during off-road driving. Oil-filled shocks and independent suspension help the truck maintain stability even when driving across rough terrain.

Available in Blue/White and Red/Black, the ARRMA MOJAVE GROM delivers a realistic desert racing look combined with dependable performance. With a sale price of $169.99, it offers an accessible way to experience ARRMA quality without the cost or size of larger RC vehicles.

Key Features

Authentic Desert Truck Design

The ARRMA MOJAVE GROM features a body inspired by full-scale desert racing trucks. The low profile and wide stance improve stability while maintaining a realistic off-road racing appearance.

This design helps the vehicle remain planted at speed while cornering on dirt or gravel surfaces.

4WD Drivetrain

A full-time four-wheel drive system sends power to all wheels, providing improved traction across uneven terrain. This allows the truck to maintain control on loose dirt, gravel, and other off-road surfaces.

The drivetrain uses durable metal gears to increase reliability during aggressive driving.

MEGA 380 Brushed Motor

The ARRMA MEGA 380 brushed motor delivers reliable performance and strong torque for a small-scale vehicle. Brushed motors are a great choice for beginner drivers because they are simple to maintain and provide smooth throttle control.

This setup offers exciting speed while keeping the truck manageable for new RC drivers.

Spektrum SLT2 2.4GHz Radio System

The included Spektrum SLT2 transmitter provides precise steering and throttle control with dependable signal stability.

A useful feature of this transmitter is throttle limiting, which allows drivers to reduce the vehicle’s power while learning to drive.

Spektrum Smart Electronics

The MOJAVE GROM includes a Spektrum SLT 2-in-1 25A waterproof ESC and receiver. This compact electronic system simplifies wiring and improves reliability.

The vehicle also uses a Spektrum SX110 waterproof metal-gear servo for accurate steering control.

Clipless Body Mounting

ARRMA designed the truck with a clipless body system, allowing the body shell to snap securely onto the chassis without traditional body clips.

This makes battery access faster and eliminates the frustration of losing small clips during maintenance.

Technical Specifications

These specifications show that the MOJAVE GROM is built with the same attention to durability and performance found in larger ARRMA vehicles.
