TRACTION Hobby KM Challenger 1/6 Scale 4WD Solid Rear Axle RC Desert Truck — ARTR / RTR

TRACTION Hobby KM Challenger — 1/6 Scale RC Desert Truck with Solid Rear Axle

The KM Challenger is not your typical RC truck. Built on a 4 mm 6061-T6 full aluminum alloy chassis with a solid rear axle, four-link rear suspension, and full-time 4WD, it brings the mechanical layout of a real desert race truck to a 1/6 scale RC platform. At 784 mm long with a 469 mm wheelbase, this is a serious large-scale machine built for experienced RC enthusiasts who want something different.

Why the KM Challenger Stands Out

• Solid Rear Axle + Four-Link Suspension — A rare setup in RC trucks, giving it authentic desert race truck character
• Independent Front Double-Wishbone Suspension — Long-travel front suspension for realistic off-road geometry
• Full-Time 4WD with All-Metal Gears — 8.006:1 overall gear ratio, built for durability and traction
• 4 mm 6061-T6 Aluminum Alloy Chassis — Rigid, lightweight, and built to handle large-scale stress
• 1.5 mm PC Body Shell — Thick, impact-resistant body with full-size spare tire for scale realism
• Licensed 6.2 x 2.4 R2.75 Tires — Large-diameter tires matched to the 1/6 platform
• KM Genuine 4215 45kg All-Metal High-Voltage Servo — Powerful steering for a truck this size
• Dedicated Parts Ecosystem — Roll cages, bumpers, gearboxes, A-arms, and more available separately

Who Is the KM Challenger For?

The KM Challenger is built for experienced RC hobbyists who want a large-scale desert truck with real mechanical substance. If you are drawn to trophy truck and desert race aesthetics, appreciate solid rear axle chassis design, and want a platform with a dedicated aftermarket parts ecosystem, this is the truck. It is equally at home as a serious basher, a scale display piece, or a custom build platform.
