Annual Futaba / O.S.® Engine Nitro Challenge
St. Louis, Missouri
The O.S. 21 XZ M ABN powered Jerry Dunlap's Sport 20 Hydroplane to a win in the final of the Sport 20 Class at the 2012 Sport 20 Championships. The boat was driven by his son, Paul (pictured). He was TQ and won the final by over a 1/2 lap. They were running GrimRacer 50% fuel and the plug was a RP8. The engine is really running strong. A great start to the 2012 model boat racing season out in the Northwest.
