Mini Scale Desert Truck Bashing Fun

Off-road racing challenges full-size desert trucks with extreme tests of performance and endurance, and RC model versions encounter their own rigorous trials during intense bashing sessions. ARRMA’s models, like the small-scale MOJAVE GROM 4X4 Desert Truck, are built with legendary toughness to withstand these challenges. Featuring detailed desert truck aesthetics, the ready-to-run MOJAVE GROM brings the excitement of Baja-style action to enthusiasts of all skill levels. Agile and responsive like its larger counterparts, the 4S and 6S MOJAVE vehicles, the MOJAVE GROM offers the performance and durability that ARRMA is known for, in a portable size perfect for on-the-go bashing fun.




The desert truck body arrives factory-finished in two exciting color schemes, capturing the unmistakable look and form of the original MOJAVE in a smaller scale. The dBoots Fortress tires provide all-terrain traction and are mounted on durable, color-coordinated wheels, ensuring both performance and style. The body snaps onto the chassis easily, quickly, and securely, coming off with a simple press-and-release. With no tiny clips to force into place, it’s a body attachment system that’s perfect even for young bashers.


The enclosed drivetrain with rugged metal gears channels power from the MEGA 380 brushed motor to all four wheels, ensuring high traction and dependable performance on any terrain. The updated V2 differentials front and rear, enhanced with metal internal gears and cross pins to handle future power upgrades. Designed for carefree bashing in any condition.


The Spektrum Smart 2S LiPo battery with IC2 connectors powers the MOJAVE GROM for long run times. When it's time to recharge, simply plug it into the convenient Spektrum Smart G2 S10 USB-C Charger for safe, automatic charging in about an hour. The high-quality Spektrum SLT2 2-channel transmitter is perfectly sized for all drivers and can limit the vehicle's maximum speed to 50% or 75% for safe learning.
