06 FR21 Off-Road Racing Engine
High Performance. Quality. Affordable. When setting out to develop the 2006 FR21, our main goals were to build a high performance engine capable of competing at the highest levels of competition, that exceeds the highest quality standards, and is affordable. Joining forces with one of the most reputable Italian engine manufacturers, we met our goals with this latest addition to our nitro engine line. The 2006 FR21 is completely new and shares no parts with its predecessors. The 2006 FR21 was specifically developed for serious off-road racing and flat out rips in both 1/8 buggy and truggy classes.
NOTE: This engine was developed for racing purposes and is not recommended for backyard use. This engine is recommended only for experienced racers and/or under the close supervision of an experienced racer.
