The Sharp DR 90 Nemesis is a Formula One racing aircraft designed by Jon Sharp and built at the Mojave Airport by the Nemesis Air Racing Team. The aircraft is powered by a modified Continental O-200 piston engine. Nemesis originated as an attempt by Jon Sharp to build a Shoestring racer with composite skins over a steel frame. Along the way Dan Bond convinced him to use an airfoil with extensive laminar flow and finally Steve Ericson helped Jon design a sleeker all composite airframe.
Made by Sharp.
Sharp Nemesis is the predecessor of the Sharp Nemesis NXT.
