Description

Off-road racing puts full-size desert trucks through brutal tests of performance and endurance. RC model versions face their own moments of truth during no-holds-barred bashing. But those from ARRMA come prepared with legendary toughness — including the small scale MOJAVE GROM 4X4 Desert Truck. With its detailed desert truck looks, the ready-to-run MOJAVE GROM captures the thrills of Baja-style action for bashers of all experience levels to enjoy. Agile and responsive like the 4S and 6S MOJAVE vehicles, the small scale MOJAVE GROM delivers all the performance and durability that ARRMA fans have come to expect. However, you can take this one with you almost anywhere, for amped-up ARRMA bashing fun anytime you like. Indoors and outdoors, the MOJAVE GROM goes places that are off-limits to larger RC desert trucks. And it’s still engineered to the same high standards as other ARRMA vehicles. No compromises were made when reducing the size. With its smooth handling and tackle-anything toughness, you can be as aggressive as you like when you send the MOJAVE GROM through the corners and over the jumps. Built for endurance, the MOJAVE GROM survives any punishment you and the environment can dish out. 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 rugged 4WD drivetrain. Oil-filled shocks soak up bumps. A MEGA 380 brushed motor sends power through an enclosed drivetrain to four dBoots Fortress tires that turn it into high speeds. Even the Spektrum SX110 steering servo has metal gears — and it’s waterproof, like the Spektrum SLT 2-in-1 25A ESC and receiver, for trouble-free operation in any conditions. If you’re a first-time RC basher, the Spektrum 2.4GHz SLT2 transmitter helps you learn control skills safely by limiting maximum speed to 50% or 75% until you’re ready for it all. Recharging the Spektrum Smart 2S LiPo battery is also a snap. Just plug it into the Spektrum S10 Smart G2 Mini 2S USB-C Charger with the attached IC2 connector. In about an hour, your battery is safely recharged and ready for more fun. The sleek MOJAVE desert truck body comes finished in eye-catching red/black or blue/white color schemes. It mounts to the chassis with a secure but clipless quick-release mechanism that even young kids can manage easily. The wheels are color-coordinated with the body, and high-quality hex hardware is used throughout the vehicle for reliability and simplicity. You’ll find everything you need to the run the MOJAVE GROM inside the box. ARRMA upgrade parts are also available for expanding its capabilities, including a Metal Axle & Wheel Hub Set (ARA311231), Aluminum Shock Set (ARA-1567), Adjustable Steering Links (ARA340217), and a two-piece, assembled Oil-Filled Differential Set (ARA311193). Experience small scale RC bashing in a big way with the affordable ARRMA MOJAVE GROM — a bash-ready mini filled with desert truck detail. Features In The Box Needed to Complete Along with legendary toughness, the ARRMA MOJAVE GROM RTR desert truck offers the most accurate scale looks available in a mini size. Amp up your bashing with its thrilling Baja realism — and take its performance to the extreme with ARRMA upgrade parts! The ARRMA MOJAVE GROM 4X4 Desert Truck RTR is engineered and manufactured to the same high standards of durability and performance that you expect from any ARRMA vehicle. It’s just smaller! Out of the box, the desert truck body comes factory-finished in two exciting color scheme options. It captures the unmistakable looks and form of the original MOJAVE in small scale size. The dBoots Fortress tires add all-terrain traction and are mounted on tough color-coordinated wheels. The MOJAVE GROM desert truck body snaps onto the chassis easily, quickly, and securely. It comes 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 carries power from the installed MEGA 380 brushed motor to all four wheels for high traction. The entire power system is well-protected for dependable performance on all terrain. The MOJAVE GROM is equipped with new V2 differentials front and rear. The V2 differentials are improved with metal internal gears and cross pins to better handle any future power upgrades. Enjoy carefree bashing in any conditions with your MOJAVE GROM desert truck. The drivetrain is metal geared for durability. Even the installed Spektrum SX110 waterproof steering servo has tough metal gears. The Spektrum Smart 2S LiPo battery with IC2 connectors provides the power for long run times. When it’s time to recharge, just plug it into the convenient Spektrum Smart G2 S10 USB-C Charger. Safe charging begins automatically and takes only about an hour. The high-quality Spektrum SLT2 2-channel transmitter is the perfect size for all drivers. It can help you learn control skills safely by limiting the vehicle’s maximum speed to 50% or 75% until you’re ready for it all. Four AA batteries included.

  • Amazing Truck
Color: Blue
It's built really tough, my son has crashed it into rocks and sidewalks and nothing has broke. The steering did become unaligned but it was an easy repair with no parts needed. Plenty fast for a brushed motor. Excellent value for the price. The only upgrade I recommend is the 100w charger with the screen to show you all the battery info. Update: The diffs finally broke like others had said. My son was beating the hell out of it, but it should have lasted longer. The internals are mostly metal, with a small plastic gear- that's the weak point. I bought knock-offs here on Amazon for half the price of the upgraded ones sold by Arrma. The fix is easy, just wish they included the upgraded diffs with the car. ... show more

  • Best Bang for your $$$
Color: Blue
For the price, it doesn't get any better. For the size it has just enough power to be a perfect driveway/backyard basher. If you want more power, you can convert it to brushless for around $30-$50 and better shocks for around $40. The part support is going to be great because its name brand. Its perfect for kids and plenty of room to grow for more skilled drivers. I love it. The only thing that I would change right away is the shock oil, it is a little too soft. I would put about 40wt or 45wt shock oil in it. ... show more

Color: Blue
This everything I hoped it would be. I take this to the baseball field or hit the dunes and this little monster says. Feed me more. I only wish extra batteries were cheaper. Such a fun and easy to control Rc truck. Gets good air and will run through anything. Unbreakable.

  • Immediate problems and failure just parts for the moment now
Color: Blue
Servo was way off and always hangs right until it almost immediately had a dogbone break becoming just a parts piece for my 223 mojave grom which is actually assembled properly and running months later aside from a differential that didnt have its screws on arrival but beyond that I love these little things when they work and I plan to eventually make this one functional again and finally get my first 30 minites out of it but might just slap a 3s system in it I regret not going 223 again the quality is just a little better for the price ... show more

  • Amazing rc truck. Great deal for your money!
Color: Red
Amazing short course style Arrma Mojave Grom. The truck arrived in a well packaged and secure box. No damage to the box or the truck and Contents. This rc I decided on purchasing due to the fact that it had everything to run the truck right out of the box. You don't have to purchase AA batteries separately or the lipo battery or charger. It's a well thought out rc. The truck is built very tough and is durable as they come. Very scale in looks and performance. Something that a teen to a adult would be able to operate and have hours of fun with. So if your wanting a rc off road or on road truck that's easy to transport and take with you anywhere this rc truck is for you. I'd really highly recommend this rc truck to anyone who is looking for a small truck design that has it all. ... show more

  • +$80
Color: Red
Fun basher. Servo, motor, and differentials are all junk. I was very disappointed to have the differentials fail pretty quickly, they claimed "all metal gears" but put plastic cups responsible for transferring all the power into metal t bones of course they were going to fail and at $40 a pop suddenly this car is actually $80 more than the sticker suggests. The brushed motor is junk and also failed pretty quickly but I expected that and planned on upgrading to hobbywing electronics anyways. Buy the 223 brushless if you don't plan on upgrading from the brushed motor right away. That said the car handles great, it's the perfect size for small tracks and backyard fun. It's taken some big hits and doesn't brake and the tires have lasted. Good aftermarket support too. ... show more

  • Great car.
Color: Red
Worth every penny, however the charger broke, as many others have complained, almost instantly. Since I was doing a brushless upgrade it wasn't a big deal for me. Way faster and better built then my Latrax and that's without ever being able to actually charge the factory battery. If you plan on keeping the car brushed, nothing wrong with it plenty fast from the factory, buy a decent charger or change the factory leads and enjoy. DO NOT expect the factory charger will work. It's crap and they'd be better off not including it. It was only a capacitor that went bad, a simple fix. However there are approximately 0 schematics that tell the specification of that capacitor and I tried 4 different ones none of which worked. I ended up deciding since it charges lipos it wasn't worth the risk to fix. Put too large of a capacitor in next thing you know it's charging to 4.8 volts. Just expect you need a charger from the beginning and problem solved. Update: I just bought a Typhon and the exact same thing happened. So it's definitely the charger. Skip this unless you want it as a chassis. In other words you plan to go brushless from the start or buy a new charger. ... show more

  • Simply awesome
Color: Blue
AWESOME! I have owned many traxxas trucks and can honestly say this is so much more fun, I purchased for my 7 year old son but have a hard time not playing with it myself. It takes a beating and is built like a tank it will not break. I was shocked on just how fast it is, there’s just something about a smaller rc truck it’s just fun! It handles amazing the suspension is great right out of the box. And yes it is ready to run you don’t need to purchase anything else. So cool I had to buy another one we now have 2 to race each other. ... show more
