Are you ready to beef up your remote-control vehicle? Check out this Traxxas nitro-racing engine. It comes with a pull start and IPS shaft. This engine has a lightweight reciprocating assembly, which means better revving performance and less stress on the parts. The knife-edged connecting rod minimizes drag, and the channeled design pushes oil effectively down to the crankshaft. The slide-type carburetor means less restrictive airflow, more power, and better throttle response.
