Plastic Chassis
The chassis on an electric RC is normally plastic for toy-grade RCs and high-grade plastic for hobby-grade RCs. Carbon-fiber components are now readily available for hobby-grade RCs to give them an overall chassis performance upgrade. Carbon-fiber chassis components for hobby-grade RCs help give the chassis strength and at the same time decrease the weight of the vehicle. Other components attached to the chassis, such as shock towers, are also made of carbon-fiber. This further reduces the overall weight of the hobby-grade electric RC.
Metal Chassis
The nitro and small gas engine RC chassis is primarily made of a lightweight anodized aluminum. Metal, rather than plastic, is required because nitro and gas engines produce a lot of heat that would definitely melt any kind of plastic chassis. The aluminum chassis on a nitro or small gas engine RC also acts as a heat dissipator. The aluminum used in the chassis is a metal known for its heat-reducing properties. The engine itself is mounted on aluminum motor mounts that directly mount onto the chassis further helping to keep the engine cool.
