The ARRMA Mojave GROM 223S BLX is a compact desert truck featuring a Spektrum 2838 4500Kv brushless motor, a 25A ESC, and a 4WD drivetrain. This RC desert truck reaches 35+ mph on 2S and 50+ mph on 3S, with waterproof electronics, Dynamic Stability Control (DSC), and dBoots Copperhead 2 tires. Its Baja-style body and LED lighting make it a choice for hobbyists interested in remote control desert trucks for bashing or racing on mixed terrain.

Performance

The Spektrum 2838 4500Kv brushless motor and 25A ESC deliver strong acceleration and top speeds of 35+ mph on 2S (included battery) or 50+ mph on 3S. Full-time 4WD with oil-filled differentials and Copperhead 2 tires provides excellent traction on dirt, grass, gravel, and pavement. DSC with four modes enhances stability, while throttle limiting (50%/75%) aids skill development. Runtime averages 15–20 minutes on the included 2S 1400mAh LiPo, with efficient cooling provided by a high-speed fan.

Build Quality

Strong composite chassis with ventilation slots, metal gears in enclosed drivetrain, and heavy-duty components ensure durability. The polycarbonate Mojave body with separate bumpers survives rollovers and crashes. Waterproof ESC/receiver/servo protect against puddles and dust. The GROM platform is bash-ready, with users reporting excellent longevity even after heavy use.

Control

The included Spektrum SLT2 2-channel transmitter offers proportional steering and throttle with ~200 m range. 25A ESC provides smooth power delivery and adjustable settings. Response is crisp—ideal for high-speed maneuvers. Transmitter requires 4×AA batteries (included in some kits; check packaging).

Authentic Mojave Baja-style body in white/red with detailed graphics, functional LED headlights/taillights, and quick-access battery tray. Includes DSC with selectable modes and throttle limiter for safe progression. The truck arrives fully factory-assembled and tuned.
