Dwayne,
The original Nemesis was a F1 and dominated the class for many years. The new Nemesis NXT is for the Sport Unlimited class at the Reno Air Races. The planes have to be commercially available with a certain quantity built or sold as kits. Not sure of the number. John Sharp's and at least one other NXT have been racing at Reno. It is truly a built for speed airplane.
