At 1/18 scale, it's small enough to take along anywhere, letting you get in a driving session during your office lunch break or in the backyard. Whether you're a new driver or an experienced RC fan, the GRANITE GROM makes it easy to have fun. ARRMA made no compromises when shrinking this truck, engineering it to the same high standards as its larger vehicles. It features a strong composite chassis, 4WD with robust metal gears, and a clipless body mount that's secure but easy for all ages to remove.The GRANITE GROM is built to handle tough tumbles. Impact-absorbing front and rear bumpers protect the chassis, while the enclosed drivetrain and waterproof electronics protect the internal parts. Even the Spektrum SX110 steering servo has metal gears for added durability. For first-time drivers, the Spektrum 2.4GHz SLT2 transmitter is a huge help, allowing you to limit the truck's maximum speed to 50% or 75% until you're ready for full power. Recharging the included Spektrum Smart 2S LiPo battery is also simple. Just plug it into the supplied Spektrum S10 Smart USB-C Charger and the Smart technology takes care of the rest.
