Sharp Nemesis NXT

The Sharp Nemesis NXT (which stands for "Neoteric experimental Technology")[1] is a sport-class kit-built aircraft. It is designed for air racing. It was designed by Nemesis Air Racing's president Jon Sharp, as a follow-on to the Sharp Nemesis. It is a single seat, single engine, low wing, retractable gear kit aircraft. As designed, the aircraft is powered by a Lycoming TIO-540-NXT Thunderbolt six-cylinder engine.[2][3]

Racing historyEdit

The prototype Nemesis NXT, race number 3x (N333XT), flown by Jon Sharp, won the 2008 Reno Air Races Sport Class championship, setting a new race record speed of 392 mph (631 km/h). During the ten-day event, Sharp set a heat record of 393 mph (632 km/h) and during the qualification, set a record of 409.297 mph (658.700 km/h), the first time a racer in this class broke the 400 mph speed barrier. Speeds of over 400 mph (640 km/h) are usually only turned in by Unlimited Class racing aircraft.[2] A second NXT, race number 42 fielded by Relentless Racing, finished fifth with an average speed in the gold race of 336.526 mph (541.586 km/h).[5]

Jon Sharp announced his retirement from Pylon Racing on August 3, 2011 as the pilot with the record number of wins in history of racing.
