Key Takeaways
- The Arrma Mojave 6S V3 EXB is a 1/7 scale, four-wheel-drive desert truck, supplied assembled as an RTR model.
- Its EXB equipment includes machined aluminium gearboxes, a 7075 T6 aluminium chassis, upgraded shocks and all-steel driveshafts.
- The brushless power system supports 4S or 6S LiPo batteries. Battery and charger are not included.
- The product page states 60+ MPH capability on 6S.
- In stock now at AT Models. Check the product page for current availability.
The Mojave is built for covering rough ground with the broad stance and purposeful look of a desert truck. This V3 EXB version adds reinforced running gear and suspension to that platform, and, importantly, it arrives as an assembled ready-to-run truck. The previous Mojave 6S EXB was available only as a roller, so this version brings the EXB specification together with installed Spektrum electronics.
In stock now: see the Arrma Mojave 6S V3 EXB product page for current availability. Remember that “ready-to-run” does not mean every item needed to drive is in the box: you’ll need to add a compatible 4S or 6S LiPo battery and charger.
What is the Arrma EXB line?
What does EXB actually bring to the truck? EXB stands for Extreme Bash: Arrma’s upgraded durability tier, using reinforced materials and metal components in key areas that take load and impact. The aim is to strengthen the parts that matter when a truck is driven hard over demanding terrain.
On the Mojave, that means the reinforcement is built into the chassis, gearboxes, drivetrain and suspension, not just suggested by the body styling. For this model, the relevant EXB hardware includes machined aluminium gearboxes, 7075 aluminium shock towers and an upgraded shock package.
EXB is a useful distinction if you want a truck designed for repeated hard use, but it doesn’t make the vehicle indestructible. Driving surface, impacts and maintenance still matter. Check fittings and inspect the truck after running, especially following a hard landing or a dusty session.

What makes the Mojave 6S EXB different?
Where is the extra strength concentrated? Start with the chassis and drivetrain. The Mojave uses an EXB anodised 7075 T6 XLWB aluminium chassis, anodised aluminium bulkheads and a split centre brace. The centre brace helps support the chassis structure while its split arrangement balances strength with chassis flex.
7075 aluminium is a high-strength aluminium alloy. In practical terms, it gives the chassis and towers a strong, rigid foundation while keeping the structure made from aluminium rather than a heavier material. The front and rear shock towers are EXB red anodised 7075 aluminium.
The front and rear machined aluminium gearboxes house the drivetrain components, while all-metal differential outdrives and gearbox internals handle power through the system. All-steel driveshafts connect the drivetrain across the four-wheel-drive platform. Together, these components focus reinforcement around the parts transmitting motor power and coping with knocks from rough running.
The suspension has its own EXB upgrade. Its oil-filled, adjustable shocks use machined pistons, precision shaft guides, X-ring seals and EXB emulsion shock caps and internals. The pistons help control oil flow as the suspension moves; the seals and guides support smooth shock action. In use, the suspension helps the truck’s tyres stay in contact with uneven ground and absorb the motion of rough terrain.
The exterior is equally practical. A new aggressive EXB body design uses clipless body retention: quick-release buttons let you remove and refit the shell without dealing with conventional body clips. The truck also comes with dBoots Fortress tyres.
Pro tip: when checking the truck after a run, look over the shocks, wheels, driveshafts and chassis for dirt, looseness or signs of impact. Stronger parts still benefit from regular checks.
Power and electronics: what do 4S and 6S mean?
Is 6S simply a bigger battery? Not quite. LiPo means lithium polymer, the rechargeable battery type used here. The “S” describes how many cells are connected in series: 4S has four cells and 6S has six. More cells in series provide a higher-voltage pack. A LiPo cell is nominally around 3.7 volts, so the simple distinction is cell count, not “six volts per cell”.
The truck’s power system comprises:
- Spektrum Firma 150A Smart V2 Waterproof ESC, capable of running on 4S or 6S. An ESC, or electronic speed controller, regulates power from the battery to the motor in response to the throttle.
- Spektrum Firma 4074 2050Kv brushless motor.
- Spektrum SR315 3-channel dual protocol receiver.
- Spektrum SLT3 2.4GHz 3-channel transmitter.
- Spektrum S665 waterproof digital steering servo, which moves the steering in response to your transmitter input.
The product page states 60+ MPH capability on 6S. Treat that as a stated capability, not a guaranteed speed for every battery or running condition. Neither battery nor charger is included, so plan for those separately. If you’re choosing a 6S pack, browse the 6-cell LiPo battery category. Confirm battery and charger compatibility before purchase.
The electronics are described as waterproof, but that does not tell you the limits for every component or situation. Check the manual for the waterproof specifications before running in wet conditions; don’t assume the whole truck can be submerged.
Who is the Mojave 6S EXB for?
Would this be a good first RC car? We wouldn’t recommend it as a first model. It’s a large-scale, high-powered truck intended for drivers who are already comfortable controlling a fast RC vehicle and carrying out routine checks and maintenance.
It’s a strong fit for:
- Experienced bashers looking for reinforced components for hard use.
- Speed fans interested in the stated 6S performance capability.
- Desert-truck enthusiasts who value the scale-inspired body and wide, purposeful stance.
Before buying, make sure you have room to run a 1/7 scale vehicle safely, and budget for the necessary 4S or 6S LiPo battery and charger. If you’re new to the hobby, consider getting familiar with the controls and LiPo handling before stepping up to a model with this level of power.
