ARRMA MOJAVE GROM 223S BLX Small Scale RC Desert Truck RTR Overview

When ARRMA added the MOJAVE desert truck to our GROM 4X4 lineup, the standard for small-scale basher performance rose to a whole new level. Agile and responsive like the 4S and 6S MOJAVE vehicles, the MOJAVE GROM captures Baja-style thrills for bashers of all experience levels to enjoy — at a low cost and in a size that goes almost anywhere. Now ARRMA introduces a brushless version, the MOJAVE GROM 223S BLX. For first-time drivers who have big plans for the future, it's the ideal choice of basher to grow on.

ARRMA created the 223S series because no one wants to compromise when choosing their first or next RC vehicle. You don't want to sacrifice capabilities to get a low price, or blow out your budget to get performance that grows with your skills. You want it all, and you can have it in the MOJAVE GROM 223S BLX. Low cost, legendary toughness, and the ability to advance from 2S into 3S power are all available in this one desert truck.

Using a 2S LiPo battery, the MOJAVE GROM 223S BLX offers comfortable, beginner-friendly 35+ mph top speeds that match or beat other manufacturers' 2S bashers. Later, when you've gained some experience, drop in a 3S battery. Now your MOJAVE GROM 223S BLX can unleash thrilling speeds that reach 50 mph or more!

You'll advance into faster speeds and higher performance without buying another model or making expensive upgrades. The upgrades needed to reach 3S specs are already included and installed in the MOJAVE GROM 223S BLX, adding to the exceptional value of its low price. What's more, when you first step up to 3S power, the MOJAVE GROM 223S BLX has special features that ease you into the upper reaches of its speed range.

One of those features is the Dynamic Stability Control (DSC) built into the desert truck's Spektrum electronics. With four selectable modes, DSC will automatically correct steering input as needed to improve your control, confidence, and safety, whether you're bashing on high-grip or low-grip surfaces. As you gain experience, just turn off the DSC and succeed with the skills you've learned.

Another aid for drivers on the grow is the throttle limiting feature of the included Spektrum SLT2 2-channel transmitter. It can help you learn control skills safely by limiting the desert truck's maximum available speed to 50% or 75% until you're ready for it all. Throttle limiting, DSC, and your choice of 2S or 3S battery all work together so you'll never worry about moving faster than you can manage. Driving the MOJAVE GROM 223S BLX, anyone can make the transition from 2S to 3S speeds with absolute confidence.

Off-road racing puts full-size desert trucks through brutal tests of performance and endurance. RC versions face their own challenges during no-holds-barred bashing. The MOJAVE GROM 223S comes prepared. Its strong composite chassis is ventilated to help on-board components keep their cool, aided by a high-speed fan integrated into the electronics. Robust metal gears support the enclosed 4WD drivetrain, now equipped with oil-filled differentials.

Tough, fast, and conveniently small, the ready-to-run ARRMA MOJAVE GROM 223S BLX is the best value you'll find in RC bashers. Get everything you want — scale looks, easy control, and advanced capabilities — and compromise nothing.

Questions & Answers
Real questions from real customers. Why not ask your own?
What is the scale
Will / 20th March 2026

The Arrma Mojave Grom is a 1/16 scale

Steve @ Wheelspin Models
How different is it to brushed model
Steven / 29th September 2025

The whole drivetrain is stronger, diffs, shafts etc and the car is twice the speed.

To convert the brushed to brushless is a very expensive option and we would not recommend it , the brushless is the way to go.

Steve @ Wheelspin Models
Does it come with a controller and everything
Kacper / 11th August 2025

Yes this version is RTR with everything included.

Rich @ Wheelspin Models
