6061-T6 Anodized Aluminum 3mm Chassis Plate

Equipped with a solid 6061-T6 anodized aluminum 3mm chassis plate, this nitro Truggy delivers extreme rigidity and race-winning stability. The hardened chassis provides exceptional impact resistance and virtually zero flex, ensuring precise handling at high speeds. Combined with full 4WD traction and professional nitro power for ultimate performance.


Product Details

Extended Run Time Fuel System

Equipped with a powerful .21 engine and leak-proof 125cc large-sized fuel tank with a long overflowed aluminum material pipe, allowing your car to continue driving for up to 20 minutes. The aluminum pipe is resistant to high temperature and corrosion. We also have designed a dust cover for the air filter to ensure longer use. Overall chassis design feels more sturdy and stronger.

Product Details

9KG Metal Gear Steering Servo

For a 1/9 scale nitro RC car, a 9kg metal gear steering servo is essential for precise control. It provides the strong 9kg of torque needed to turn the large wheels against high-grip surfaces. The metal gears are durable and impact-resistant, with less play than plastic, ensuring accurate steering and preventing stripped gears under the engine's vibration and high-speed cornering forces.

Product Details

A polycarbonate (PC) body

A polycarbonate (PC) body is the essential armor for a nitro RC car. Its primary function is lightweight protection; it absorbs and deflects impacts from high-speed crashes and rollovers without adding significant weight, safeguarding the delicate engine and electronics inside. Furthermore, its rigid structure helps manage aerodynamics at high speeds, improving stability and handling on the track.
