What is the USRA?

     The Unlimited Scale Racing Association is the official sanctioning and rules body for the sport of Giant Scale Air Racing.  Founded in 1994, the purpose of the USRA is to provide the special interests of its membership a clear and definitive set of racing rules and procedures and to effectively separate those racing rules and procedures from the promotional aspects of the racing event organizers, thereby allowing uniform application of racing rules and procedures at all racing events.  By providing a fair and equitable playing field to its membership, the USRA serves to advance the sport of giant scale air racing in the areas of competition, safety and technology development for the benefit of those persons interested in the design, construction and flight of giant scale racing aircraft.

What is Giant Scale Air Racing?

     Created in 1991 by Tom Easterday and Cliff Adams, giant scale air racing was patterned after the Reno National Air Races as a way to bring the excitement, sound, color and history of air racing up close to the public and the world of radio control enthusiasts.  Since its inception, giant scale air racing has evolved steadily into a sport where speed and technology advancements know no bounds.  Speeds well in excess of 200 miles per hour make giant scale air racing one of the fastest motor sports in the world!  Racing action now encompasses six classes of racing that include: Unlimited, AT-6 Texan, Formula One, Biplane, Experimental, and Thompson Trophy.  The Thompson Trophy Class is the latest addition to the racing classes and adds the rich history, traditions and glamour of the Cleveland National Air Races to the sport of giant scale air racing.

     The number of national and international USRA giant scale racing events grows each year.  It is the intent of the USRA and each racing event organizer to continue to advance and grow the sport of giant scale air racing in order to increase awareness of our deeply rooted aviation heritage and the sport of air racing in the United States and world-wide.  Please join us in our journey as we make aviation history once again!
