RC Glossary


New to the RC Hobbies? What does buggy, bulkhead, nitro mean in radio control car hobbies? Check out the glossary for remote control cars below.

Port --

The openings or passageways in a nitro engine's sleeve and crankcase that transfer the air/fuel mixture and exhaust gasses while the engine is running. Ports are opened and closed by the piston as it moves up and down in the sleeve (the induction port is opened and closed by the crank's rotation). The port position, area, and shape affect engine timing and performance. In gas engines (fuelies), the intake and exhaust ports are conventional valve operated openings above the combustion chamber. Nitro engines are commonly rated by the number of ports in the sleeve - unless otherwise noted, the number usually does not include the crank or exhaust ports, but does include satellite and guide ports. Either way, more ports do not guarantee more power.
