The Parker 2nd Ranger, also called the Parker Ranger is an American mid-wing, single-seat motor glider that was designed and constructed by W.L. Parker of La Grande, Oregon, first flying in 1967.[1][2][3]
Design and development
Parker originally built the Ranger and equipped it with a 15 hp (11 kW) and a 31 in (79 cm) propeller that was unable to provide enough thrust to allow the aircraft to take-off. The engine was replaced with a Richter 35 hp (26 kW) powerplant which rectified this defect. The engine is retractable and mounted behind the cockpit.[1][2]
The aircraft is constructed from aluminium. The 37.5 ft (11 m) wing employs a laminated aluminium spar and a NACA 4418 airfoil. The Ranger is not equipped with any glidepath control devices, such as dive brakes. The landing gear is a single centreline mainwheel plus a nose-mounted second wheel to allow taxiing.[1][2]
The aircraft was registered with the Federal Aviation Administration in the Experimental - amateur-built category. Only one was built.[1][2]
