Plans and kits are available to the homebuilder for the Monarch C ultralight motorglider. Power is supplied by a 12-hp McCulloch engine located behind the pilot’s seat; however, engines up to 20 hp can be used. The high wing makes use of a wooden rear spar with woodand-foam ribs. Fiberglass covers the leading edge, and […]

The Monerai follows the precedents set by its VW-powered sportplane siblings Sonerai I and II by offering simplified construction and economy with high performance. Designed for the first-time builder or the expert, the Monerai can be either a true sailplane for the purist or, with the addition of a podmounted engine, a self-launching sailplane for […]

Vernon Oldershaw’s motorglider features a retractable power plant that can be used for takeoff and climb to soaring altitude. A 31-hp Yamaha snowmobile two stroke flat-twin engine drives a wooden pusher propeller and feeds from a N-gallon fuel supply. The shoulder-type wings are built with a spruce spar, plywood ribs, and plywood skin; the wing […]

The Orlik 2 first flew in 1938, and an improved variation, the Orlik 3 competed in the 1940 Olympic Games. It had airbrakes beneath the wings. The design briefly held a world altitude record in 1948 of 30,000 feet.

The PIK motorized glider has a manually retractable engine and propeller. The Rotax 503 500cc two-stroke two-cylinder engine produces 43 hp at 6,200 RPM. With double carburetors and resonance exhaust system, the whole snowmobile engine has been redesigned and built to aircraft requirements. The propeller is belt driven giving a 1:2 reduction. When not in […]

The only glider manufactured by Swiss aircraft manufacturer Pilatus was the B4. About 300 were produced beginning in 1972 until the Japanese company Nippi bought the rights to the design. The P4 is all metal and economical to maintain, and has good acro capabilities.

This sleek motorglider is essentially a stock KR-1 with longer wings and a bigger tail. For a wing curve, an RAF-48 standard KR-1 airfoil was used for the center section and the GA(W)-2 airfoil for the replacement outer panels. The outer wing section provides a clean and responsive curve for use with a spoiler/flap control, […]

The Cloudster is a powered sailplane or an airplane that soars, whichever you prefer. The all-metal airplane is fitted with a 100-hp Continental and a Wortmann FX 67-170/17 airfoil. The flaps, which also serve as airbrakes, are electrically actuated, and the ailerons and flaps are interconnected to operate together from -12 degrees to +8 degrees. […]

SF-25 SF-28A The two-place all-fiberglass SF-H34 has pleasant flight characteristics and a low construction weight. Schempp-Hirth airbrakes on the top surface of the wings are provided for glide-angle control. The nosewheel is fixed, and the main landing wheel is sprung. A disc brake is mounted with the main landing wheel. Visibility is excellent through the […]
