Introducing the officially licensed FMS 1/24 scale FCX24 Mercedes-Benz Unimog 421 Rock Crawler. Authorized by Daimler-Benz AG, this model features a highly detailed grille, widened rear-view mirrors, snorkel, and orange warning lights. The engine hood can be opened for battery replacement and serves as storage for the electronic board. The rear cargo compartment and three-side wall panels are made of intricately patterned wood, simulating real wood texture.
The FCX24 chassis is a high-performance, high-strength integrated nylon molding with metal side beams, providing a durable and rigid platform. Its multi-link suspension with coil springs and hydraulic shock absorbers ensures maximum axle articulation over rough terrain. The two-speed high-torque transmission transmits power to the front and rear axles through metal universal drive shafts, equipped with portal axles for increased ground clearance and reduced differential load. The low gear ratio of 99:1 offers strong climbing torque, while the 24.75:1 ratio provides a top speed of up to 8km/h. The 2-speed gearbox is operated by the transmitter via an on-board servo.
The Unimog 421 features an easy-to-remove ABS hard bodyshell, providing highly accurate scale detail and durability. It also includes a fully functioning light system with headlights, turn indicators, and roof lights for added realism. The model arrives ready to run, fully assembled with water-resistant electronics, including a high-torque brushed 130 motor, 2-in-1 receiver/ESC, metal-geared steering servo, and a 7.4V (2S) 380mAh LiPo battery for up to 30 minutes of run time. Simply charge the battery with the supplied USB charger, install 4 x AAA batteries into the included transmitter, and you're ready to go.
