## Description

Amped-up ARRMA RC blasting gets "fun-sized" with the fast, tough, and ready-to-run GRANITE GROM 4X4 Monster Truck. At 1/18 scale, it's small enough to take along anywhere. And the GRANITE GROM delivers a big dose of genuine ARRMA performance and durability whenever you get the urge to bash.  Enjoy some after-school RC monster truck action with friends. Sneak in a little bashing during your office lunch break. Whether you're a young beginner or an experienced RC basher, the GRANITE GROM easily fits time for ARRMA RC bashing into your way of life. It's tough, fast — and conveniently small.  Unlike many manufacturers of mini RC models, ARRMA made no compromises when shrinking this basher down to small scale size. The GRANITE GROM 4X4 Monster Truck is precision-engineered to the same high standards as larger ARRMA RC vehicles. It also has a clipless body mount design that keeps the body securely attached but easy to remove for all drivers, young and old. Among small scale RC basher models it's in a league of its own, with convenience plus the power, strength, and handling capabilities you need to get serious about your stunts.  The ARRMA GRANITE GROM 4X4 Monster Truck endures any punishment you can dish out. Impact-absorbing front and rear bumpers are the bash-ready bookends to its strong composite chassis. A 4WD transmission with robust metal gears carries power from the MEGA 380 brushed motor through an enclosed drivetrain to the tough dBoots FORTRESS monster truck wheels and tires. Even the Spektrum SX110 steering servo has metal gears — and, like the IC2 connector-equipped Spektrum SLT 2-in-1 25A ESC and receiver, it's waterproof for carefree bashing 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 the monster truck's maximum speed to 50% or 75% until you're ready to handle it all. Recharging the included Spektrum Smart 2S LiPo battery is also worry-free. Just plug it into the supplied Spektrum S10 Smart G2 Mini 2S USB-C Charger with the attached IC2 connectors. Smart technology instantly takes care of the rest. In about an hour, your battery is safely recharged and ready for another round of fun.  Everything you'll need to the run the GRANITE GROM comes in the box. The truck body is professionally factory-finished in your choice of three brilliant, durable color schemes. GRANITE GROM upgrade parts are available for cranking up its capabilities past eleven. They include a Metal Axle & Wheel Hub Set, Aluminum Shock Set, Adjustable Steering Links, and a two-piece, assembled Oil-Filled Differential Set.  Take advantage of small scale value and versatility with the GRANITE GROM 4X4 Monster Truck RTR, and experience ARRMA RC bashing excellence for yourself.  Awesome monster truck styling with three color choices Powerful Spektrum 2S LiPo battery and safe, easy-to-use Smart charger Easy body attachment and removal Enclosed drivetrain for all-terrain protection Reliable, high-quality hex hardware Independent suspension and oil-filled, coil-over shocks Tough monster truck wheels and tires Impact-absorbing front and rear bumper Spektrum SLT2 2-channel 2.4GHz radio Spektrum SLT 2-in-1 25A waterproof ESC and receiver Spektrum SX110 waterproof metal-geared servo 2-Year limited warranty (see website for details)

## Customer Reviews

### ⭐⭐⭐⭐⭐ Worth every penny
*by D***D on October 18, 2024*

We live in the country so I wanted an off road vehicle that was durable, fast and cost effective. The mini Granite has been the perfect addition to the fleet. It’s small enough I can take it anywhere and doesn’t require a bunch of parts. It just works. It’s not a rocket but it also doesn’t break when it wrecks. It’s not brushless so it can get a little wet. The body is thick and shows little to no use. Ours mostly gets used on mowed lawns, gravel and dirt. Replacement parts are cheap and available if needed but I’ve yet to break anything.

### ⭐⭐⭐ Fast and fun but you need to be capable of replacing parts.
*by B***N on February 4, 2025*

This thing is a blast to drive. It's been charged about 6 times total so far and the rear differential is already blown. I'm not a fan of weak components. I'll try another brand after some research. I understand this is a budget rc truck but I would expect it to last a longer than 6 battery charges before a component broke on it... I would consider this a hobby grade RC and it has parts support but I just wish it lasted longer. Right now it works but it just does fwd burnouts because the rear differential blew on it. 3 our of 5 because it's still a blast to drive once repaired. And after my research, the cost to fun ratio is still very nice.

### ⭐⭐⭐⭐ Very hard to get body on and off
*by B***. on November 19, 2024*

Great RC car for beginners with adjustable power settings. Body can be very difficult to get on and off and the charger that comes with the car quit working after 3 charges and had to get a lipo smart charger to charge the batteries.
