This compact 1/16 scale size means the truck fits easily in backpacks, cars, and storage spaces whilst maintaining excellent durability and scale realism. Weighing just 2.27 pounds (1.03kg), the MOJAVE GROM 223S BLX is light enough for young bashers to handle and transport, yet substantial enough to deliver genuine performance and durability. The 12mm hex wheel attachment system uses reliable, high-quality hex hardware that's tough enough for repeated impacts and crashes without stripping or loosening.
Suspension geometry features independent, oil-filled coil-over shocks that provide consistent dampening throughout extended bashing sessions. The oil-filled design prevents the suspension from fading or becoming soggy when hot, maintaining the truck's handling characteristics whether you're on your first run or your twentieth consecutive battery pack. The robust drivetrain features metal gears throughout, with an enclosed design that protects the power transmission system from dirt and damage whilst distributing forces evenly across all four wheels via the oil-filled differential set.
Power delivery is managed through the Spektrum Smart 7.4V 1400mAh 2S 30C hard case LiPo battery with IC2 connectors, which delivers approximately 35+ mph of speed in standard 2S configuration. The battery charges quickly via the included Spektrum S10 Smart G2 Mini USB-C charger in approximately one hour, meaning you can be back on the track within a short time of finishing a battery run.
