Overview
Driving a small-scale desert truck over dirt and sand is the idea behind this ARRMA Mojave GROM. It has four-wheel drive, a brushed motor and waterproof electronics, and everything needed to run is in the box.
Buyers get a complete package with a Spektrum Smart battery, a USB-C charger and four AA batteries for the transmitter, so nothing extra is required. Speed and run time are not listed, and the motor is brushed, which matters to speed-minded drivers.
Who it's for
Hobbyists who drive in sand, dirt and wet conditions get waterproof electronics and a metal-geared servo. Small kids and racers wanting extreme speed should choose another model.
Pros and cons
- Battery and charger included
- Waterproof ESC and servo
- Transmitter batteries included
- Metal, plastic and rubber build
- Top speed not listed
- Run time not listed

Performance notes
A brushed motor drives all four wheels, and the waterproof speed control and receiver protect the electronics in wet conditions. The 2S Smart battery sets run time, and the Smart charger tops it up over USB-C.
