The desert truck that first carved its name into the RC landscape is back on the shelves. ARRMA has resurrected the 1/7-scale MOJAVE 6S 4X4 platform with two new ready-to-run variants: a standard RTR and a heavily reinforced EXB version.
The Mojave name has been absent from the RTR lineup since 2020, and the 6S EXB variant was previously sold only as a roller. Now both models ship fully assembled, needing only a battery and charger to tear up the terrain.
Two Paths to High-Speed Desert Bashing
The ARRMA MOJAVE 6S 4X4 RTR pairs a stout foundation with serious speed. A 7075 T6 XLWB aluminum chassis provides a rigid backbone, while all-steel driveshafts, all-metal diff outdrives, and a split center brace balance strength with controlled flex. Power flows from a Spektrum Firma 150A Smart V2 Waterproof ESC coupled to a Spektrum Firma 4074 2050Kv brushless motor, ready to run on 4S or 6S LiPo and hit 60+ MPH on 6S. Improved ESC firmware, carried over from other recent 6S releases, promises smoother throttle response. The truck rolls on dBoots Fortress tires and uses oil-filled adjustable shocks with EXB emulsion caps. A new hidden clipless body retention system with quick-release buttons on each side speeds up pit stops, and integrated inner arches in the body frame help keep dirt and debris out.
For serious bashers, the ARRMA MOJAVE 6S 4X4 EXB RTR layers on premium reinforcements. Machined aluminum gearboxes front and rear, EXB red anodized 7075 aluminum shock towers, and an EXB 7075 aluminum anodized chassis set it apart. The shock package gains machined pistons, precision shaft guides, and X-ring seals, with EXB emulsion shock caps and internals dialing in the suspension for hard landings. Anodized aluminum bulkheads and reinforced braces add further rigidity, while the same proven Spektrum brushless system and clipless body design carry over. Both trucks share the same 1/7-scale footprint, long wheelbase, and wide stance, engineered for stable desert handling across dirt, sand, asphalt, and grass.
Pricing and Availability
The standard ARRMA MOJAVE 6S 4X4 RTR is offered in three finishes. The source materials refer to part ARA7604V3T1 as a Blue body and part ARA7604V3T3 as an online-exclusive limited-edition Yellow body, each at $719.99. For part ARA7604V3T2, the listing’s features section notes a Beige option, while the pricing section describes it as a “white body” — both at the same $719.99 price. Buyers should confirm the exact shade at their retailer.
The ARRMA MOJAVE 6S 4X4 EXB RTR is listed under part number ARA7704V3T1 with a retail price of $849.99. Batteries and charger are sold separately for both models. Both trucks come equipped with the same Spektrum electronics suite: the S665 Waterproof Digital Steering Servo, SR315 3-Channel Dual Protocol Receiver, and SLT3 2.4GHz 3-Channel Transmitter. A 2-year limited warranty is included (details on the manufacturer’s website).
Getting On the Road
Each box contains the truck with installed electronics, a pinion gear, four AA transmitter batteries, and an instruction manual. To get running, owners need one or more LiPo batteries with IC5 connectors and a compatible charger. ARRMA recommends configurations ranging from two 2S or two 3S hardcase packs to a single 4S or 6S hardcase battery, along with a LiPo-safe battery bag.
The Mojave is back in two distinct flavors: the reinforced EXB for maximum abuse tolerance and the standard RTR for proven performance. Both are designed to deliver serious speed straight out of the box.
