The ROFUN LT450 is a 1/5-scale gasoline RC off-road car, high-configuration version. A 45cc-class two-stroke engine with a recoil pull starter drives a shaft-driven 4WD system with front, center and rear differentials. Braking uses a differential dual-disc arrangement.
The one-piece chassis is CNC-machined from 5mm 6061-T6 aluminum with a hard-anodized finish. CNC metal parts include the front and rear support beams, shock towers, a steering-servo support bridge, a servo retaining plate and a center differential cover. Front and rear all-metal hydraulic shock absorbers and anti-roll bars at both ends make up the suspension. Split polycarbonate body panels and a removable roll cage allow access for inspection and servicing.
The car is 965mm long and weighs 18.5kg, so it needs suitable outdoor space. The engine runs on a premix of gasoline and two-stroke oil, and routine engine and drivetrain maintenance is part of owning it. A 6V NiMH battery powers the onboard electronics and servos. It must be charged before operation, while the gasoline engine drives the wheels.
