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.

Four Stroke - 4 Stroke - Thumper (Nitro Engine) --

An RC nitro engine that fires once for every 2 up and down cycles of the piston, as opposed to a 2 stroke that fires once for every up and down cycle of the piston. 4 stroke engines use a valve system similar to 1:1 vehicles, complete with valves, pushrods, rockers, and a crank driven cam. So, you won't find any ports in the sleeve (since intake and exhaust is taken care of by the valves), but you will find ring(s) on the piston because 4 strokes require more compression than 2 strokes. 4 stroke engines are known for insane torque and excellent fuel economy, but are also known for lots of vibration - so pad those electronics and make threadlock your friend.
