The Sharp Nemesis NXT (which stands for "Neoteric experimental Technology") is a sport-class kit-built aircraft, designed for air racing. It was designed by Nemesis Air Racing's president Jon Sharp, as a follow-on to their Sharp Nemesis. It is a two-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.
In 2011 the German company Air-C-Race became the official builder of RC models of the Nemesis NXT.
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 had broken the 400 mph speed barrier. Speeds of over 400 mph (640 km/h) are usually only turned in by Unlimited Class racing aircraft. 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).
Jon Sharp announced his retirement from Pylon Racing in August 2011, as the pilot with the highest number of wins in the history of racing. In 2015 he was invited to donate his prototype Nemesis NXT to the National Air and Space Museum, and it was delivered in 2018 by Crew Chief Steve Hill and race pilot Justin Phillipson. Museum directors planned to display it in their Nation of Speed gallery at the museum's central site, but when they realized it was too large to fit through that building's access door, they moved it to the Steven F. Udvar-Hazy Center in Fairfax County, Virginia, where it is on permanent display (as of 2022) in the Boeing Aviation Hangar alongside its older sibling, Nemesis.
On 30 July 2008, Sharp set an FAI class C1b world record for speed over a straight 3 km (1.9 mi) course at 573.46 km/h (356.33 mph).
On 20 September 2009, Sharp won the Super Sport Gold race at Reno with a speed of 407.061 mph (655.101 km/h).
On 16 September 2009, Sharp qualified first with a speed of 412.554 mph (663.941 km/h) for the top spot in the Super Sport class at Reno.
On 17 September 2009, Sharp set a Super Sport race record of 383.292 mph (616.849 km/h).
On 18 September 2009, Sharp beat the previous day's record with a speed of 399.336 mph (642.669 km/h).
On 19 September 2009, the aircraft reached 406.051 mph (653.476 km/h), the first homebuilt aircraft to exceed 400 mph (640 km/h) average race speed on the Reno course.
On 20 September 2009, Sharp won the Super Sport Gold race at a record speed of 407.061 mph (655.101 km/h). He earned his 15th National Championship (another record) completing the "Record a Day and Two on Sunday" Reno campaign of 2009.
In September–October 2015 Sharp set five FAI records for piston aircraft at Moriarty, New Mexico; all are current in 2022:
- In the under-1000 kg weight class C1b, average 393 miles/hour for four 3-km runs at low altitude; and 406 miles/hour for two 15 km runs at unrestricted altitude
- In the under-1750 kg weight class C1c, average 415 miles/hr on the 3-km course, 407 miles/hr on the 15 km, and 397 miles/hr for a 100 km circuit.
