Kensgaila VK-8 Ausra

Design of this two seat agricultural homebuilt was undertaken by Vladas Kensgaila in Lithuania. Panevezys District “Dawn” kolkhoz (Chairman Vilius Pasiukas) decided to pay the costs. Pasiukui, over the years, have not changed, and thousands of bills paid for the materials. Work began in 1987 and the construction of the prototype began in 1989 and later that year the VK-8 appeared at the 5th National Homebuilt Convention held at Riga. At that time it was the largest homebuilt in the Soviet Union and carried the Lithuanian registration LY-21. The designer was hopeful of series production.

It was an aircraft designed for agricultural, training and transport roles, and conformed to experimental regulations. It was a strut-braced low-wing monoplane, of composite construction. It had three axis control plus flaps, leading-edge slats and electric trim. Spray booms were carried below the wing trailing edges ahead of the ailerons. The undercarriage was not retractable and the main wheels were fitted with trouser fairings and brakes.

It had a high raised cockpit, slightly forward of the wing which gave a good view. An 800 litre container was carried behind the cockpit for 309 kg and the VK-8 could spray a swathe of 30 metres width. The Vedeneyev 360 hp radial engine drove a two bladed variable pitch wooden propeller with reduction gearing. The airscrew diameter was 2.75 m. Powered by a 360 hp power M 14 F engine, either the M-14P or M-14PS could be fitted.

The plane was built in two years. The VK-8 Ausra two-seat agricultural aircraft first flew in May 1989 piloted by Vlad Kensgaila, from Panevezys aviation technical sports club hangar.

Designed as a potential An-2 replacement, only one was built. It fully complied to FAR 23 standards.

Ken Brock KB-2 Gyroplane

First flown in 1980, the KB-2 Gyroplane has quite a few features that distinguish it from other similar aircraft. These include: an aircraft-type joystick for con¬trol; its fuel tank seat which is molded from polyurethane to save on weight and add to the clean-looking design; its choice of rotor blades and its wheels. Construction has been simplified by packaging into seven separate kits (airframe, landing gear, rotor head, rotor blades, rotor hub, joystick, rudder/horizontal stabilizer and an optional kit for a prefab metal tail). Engine: 72 or 90 hp McCulloch, VW, or similar.

The KB-2 was sold in sub-kits. Price may vary with options, but the average is $12,500 in 2001.

Kelly Hatz CB-1

Began as a parasol monoplane, N8670E, the first flight of this tandem-seater, open-cockpit biplane took place in 1968.

The wings are a fabric-covered spruce spars with truss rib structure, while the fuselage and tail are built from welded steel tubing. Bungee shocks for the gear; 6 x 6 wheels with brakes; dual controls; space for overnight bag on shelf in front cockpit; fuel capacity 33 gallons in two tanks, or 20 gallons in one tank (center section).

The design weight of the Hatz (850 pounds) makes it perform well with the 85-hp Continental and it is stressed to take engines up to 150 hp. The Hatz can be trimmed to fly hands-off (more or less), which helps out when trying to read a map in an open cockpit. Control response is slow enough to give a feeling of a much larger aircraft, and it is capable of all aerobatic maneuvers in the power range.

The Hatz CB-1 Biplane is a two place with a 90 mph cruise.

A straight-forward design with simple details and a minimum of time consuming jig work is the result of many hours of planning and testing.

First produced by John D Hatz, Schofield and Merril WI, USA, and circa 1980, Dudley R Kelly of Versailles KY., USA, plans were marketed to home-builders at $125 and kits were available from commercial sources.
