The Lancair Sentry is an American amateur-built aircraft that was designed and produced by Lancair of Redmond, Oregon, introduced in 2002. The aircraft was supplied as a kit for amateur construction, although it was also intended as a production military trainer aircraft. First flown in September 2001, only two were ever completed.[1][2][3][4]

The design was intended to compete with other similar two-seat civil designs, such as the Thunder Mustang and the Turbine Legend. Military sales prospects included the Mexican Navy, but no orders were forthcoming.[3][4]
The Sentry is a two-seat development of the four-seat Lancair IV, with the door-accessed cabin replaced by a canopy. It also has an enlarged vertical tail fin.[1][3][4][5]
The aircraft features a cantilever low-wing, a two-seats-in-tandem enclosed cockpit under a rear-hinged bubble canopy, retractable tricycle landing gear and a single engine in tractor configuration.[1]
The aircraft is made from composite materials, predominantly carbon fiber reinforced polymer. Its 30.2 ft (9.2 m) span wing employs a McWilliams RXM5-217 root airfoil, tapering to a NACA 64-212 tip airfoil. The wing has an area of 98 sq ft (9.1 m2) and mounts flaps. The standard engine used is the 708 hp (528 kW) Walter M601D turboprop powerplant powering an American 82 in (208.3 cm) three-bladed Hartzell Propeller or a Czech 84 in (213.4 cm) Avia Propeller.[1][2][4][6]
