Go brushless bashing in a big way with the affordable ARRMA® MOJAVE™ 4S BLX 4X4 Desert Truck RTR. It’s got it all — legendary toughness, dynamic handling, and the brutal speed of a Spektrum™ 4S-ready brushless power system that’s capable of 50+ mph under optimum conditions. Even better, this high-performance package comes wrapped in exciting 1/8 scale desert truck realism, complete with a detailed cockpit plus a roll cage and roof rails!

Cut loose with incredible acceleration courtesy of the factory-installed Spektrum Firma™ 2400Kv brushless motor and waterproof Firma 120A ESC with IC5® connectors. The heavy-duty composite chassis and EXB (EXtreme Bash)-enhanced transmission take it all in stride. The MOJAVE Desert Truck also introduces a rugged center diff to the ARRMA 4S BLX 4X4 platform, for truly awesome traction and handling.

You’ll find high-quality, rubber-shielded bearings throughout, plus other proven features that deliver unstoppable performance in environments ranging from off-road, dirt, and grass to parking lots, paved and asphalt surfaces. Multi-terrain dBoots® FORTRESS™ LP tires on multi split-spoke wheels give your MOJAVE 4S BLX 4X4 Desert Truck the grip to get up, over, or through any obstacle in your way. A waterproof, metal-geared Spektrum S652 digital servo keeps the steering responsive and reliable.

If you’re a new driver, you’ll be able to set the throttle limits of the included 3-channel Spektrum SLT3™ radio at 50% or 75% until you’re ready to use the full speed potential. Then punch the throttle and let the dirt fly. The ARRMA MOJAVE 4S BLX 4X4 Desert Truck has multiple layers of defense against dirt and debris — including wishbone dirt guards, a chassis dirt drain, outdrive guards for enhanced protection from rocks, and most importantly, an inner body to keep internals clean.

A LiPo battery pack and charger are all that you’ll need to complete the 1/8 scale ARRMA MOJAVE 4S BLX 4X4. Pop in a charged pack and prepare for amplified, all-road ARRMA blasting, desert truck style!

Under The Hood



Why bash when you can blast! The 4S BLX 4X4 platform is built to handle amped-up brushless power with a strong composite chassis and retained hinge pin plates; protective front and rear skid plates; steering with stone clearance; sliding gear mesh; and rubber-shielded bearings throughout.



ARRMA adds EXB EXtreme Bash parts where the extra toughness is needed most. Included in the 1/8 scale ARRMA MOJAVE 4S BLX 4X4 Desert Truck are EXB CVD front and rear driveshafts and EXB metal input and ring gears.



When the going gets rough, the tough keep going. The 1/8 scale ARRMA MOJAVE 4S BLX 4X4 Desert Truck is ready to get down and dirty on off-road tracks, with wishbone dirt guards, a chassis dirt drain, outdrive guards for enhanced protection from rocks, and — most importantly — an inner body to keep internals clean.



The MOJAVE 4S BLX 4X4 Desert Truck takes advantage of the signature ARRMA modular design for easy maintenance. Separate, easily removable chassis modules for the power system, electronics and differential components make routine cleaning and repairs fast and simple.



Long, aluminum-bodied, oil-filled big bore shocks are included and mounted on tall shock towers. These plus wide suspension arms give the ARRMA MOJAVE 4S BLX 4X4 Desert Truck plush suspension travel.



The high-quality rubber dBoots® FORTRESS™ LP tires are vented to let air in and out for improved traction and allow water and dirt to escape for longer tire life. Their multi-surface tread pattern delivers awesome traction in all track conditions. The tires are mounted on tough MT multi-spoke wheels with CNC machined, red anodized hubs.



The sleek desert truck body comes factory-finished in your choice of two exciting colors. Front and rear scale bumpers protect against impacts. Also included are rear dirt deflectors, a scale skirt, and protective grille. A wheelie bar with rubber tires provides stunt potential.



The inner body of the ARRMA MOJAVE 4S BLX 4X4 Desert Truck continues the scale looks with driver figures and interior details. There’s also an inner body protection cockpit and added dirt protection for all surfaces.



Included and installed, the punchy, 4S LiPo-capable brushless power system features a Spektrum Firma 120A Smart waterproof 3S/4S ESC and Spektrum Firma 3668 2400Kv brushless motor with Safe D pinion plus ARRMA heatsink and cooling fan.



Top speed capabilities exceed 50+ MPH in optimum conditions — but if you’re a new driver, just set the 3-channel Spektrum SLT3 radio’s throttle limits at 50% or 75% until you’re ready to handle it all. The Spektrum SR315 receiver is dual protocol. If you upgrade to a Spektrum DSMR® transmitter, you can download the free Spektrum Dashboard app for your mobile device and take full advantage of the Smart telemetry capabilities already present in the Firma electronics. Get real-time updates of ESC temperature, receiver (BEC) voltage, drive pack voltage and motor RPM.
