Overview


Amped-up ARRMA® RC blasting gets "fun-sized" with the quickly|quick}, difficult, and ready-to-run GRANITE GROM 4X4 Monster Truck. At 1/18 scale, it's small enough to bring anywhere. And the GRANITE GROM provides a huge dose of genuine ARRMA efficiency and durability whenever you get the urge to slam.


Take pleasure in some after-school RC beast truck action with friends. Sneak in a little bashing during your workplace lunch break. Whether you're a young beginner or a knowledgeable RC basher, the GRANITE GROM easily fits time for ARRMA RC bashing into your way of living. It's tough, fast — and easily small.


Unlike numerous 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 very same high requirements as bigger ARRMA RC lorries. It also has a clipless body install style that keeps the body securely connected but simple to get rid of for all drivers, young and old. Among small scale RC basher models it's in a league of its own, with benefit plus the power, strength, and managing capabilities you require to buckle down about your stunts.


The ARRMA GRANITE GROM 4X4 Monster Truck endures any penalty you can dispense. Impact-absorbing front and rear bumpers are the bash-ready bookends to its strong composite chassis. A 4WD transmission with robust metal gears brings power from the MEGA 380 brushed motor through an enclosed drivetrain to the difficult dBoots® FORTRESS beast 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 water resistant for carefree bashing in any conditions.


If you're a first-time RC basher, the Spektrum 2.4GHz SLT2 transmitter helps you find out control skills securely by limiting the beast truck's maximum speed to 50% or 75% till you're ready to handle all of it. Charging the included Spektrum Smart two LiPo battery is also stress-free. Simply plug it into the supplied Spektrum S10 Smart G2 Mini Two USB-C Charger with the connected IC2 adapters. Smart innovation immediately takes care of the rest. In about an hour, your battery is securely charged and ready for another round of enjoyable.


Everything you'll require to the run the GRANITE GROM is available in package. The truck body is professionally factory-finished in your option of 3 dazzling, resilient color schemes. GRANITE GROM upgrade parts are readily available for cranking up its capabilities past eleven. They consist of a Metal Axle & Wheel Hub Set, Aluminum Shock Set, Adjustable Steering Links, and a two-piece, assembled Oil-Filled Differential Set.


Benefit from small scale worth and flexibility with the GRANITE GROM 4X4 Monster Truck RTR, and experience ARRMA RC bashing quality for yourself.
