Precious Metal competes in the Unlimited class. This Class has generally been populated by stock or modified WWII fighters with the P-51 Mustangs, F-8F Bearcats and Hawker Sea Fury being flown most often.
There are Gold, Silver and Bronze heats; with Silver and Bronze featuring mainly stock aircaft allowing the highly modifided aircraft to fight it out in the Gold heat.
Decades ago, the surplus of these military aircraft enabled air racing to make a leap forward from the existing method of designing and building individual aircraft. Today’s racers feature a wild mixture of the original design and years of mechanical innovation created since their original build. In the best tradition of hot rodders, these race teams take the aircraft far past what any of the original designers ever imagined them beng capable of doing. Their speeds around the course can exceed 500 mph.
