Kudashev’s biplane (Кудашев) Biplane of 1910, sometimes designated Кудашев 1, was, reportedly, the first aeroplane of Russian design flown. On May 23, 1910 it flew about half the length of a football pitch at a height of a couple of feet at Kiev. The flight was not advertised and went unnoticed by the general public. Kudashev was a civil engineer and associate professor at Kiev Polytechnics.

In 2005 Petr Kubiček, encouraged by aerospace engineering students at Brno University, began to design a modernised Mráz M-2 Skaut with the hope of production. The first Kubicek M-2 Scout (the name was Anglicised) of the 21st century appeared, unflown, at Aero ’09 held in Friedrichshafen in the spring of 2009 and flew for the first time on 7 May 2009. The Scout design began with the original plans reassessed with modern methods and using a metal rather than wood structure, supplemented with some composite materials for the engines cowling and flying surface tips.
Externally the old and new aircraft are similar, wings and tail having the same features and the side-by-side seating retained. The aircraft is made from riveted and bonded aluminum sheet and is completely corrosion-treated after assembly. Electrically operated flaps are fitted to the Scout and there is a central trim tab on the elevator. Its fixed tricycle undercarriage is mounted on the fuselage with cantilever composite mainlegs. The mainwheels have brakes operated with a central lever and the nosewheel has helical springing. All wheels are spatted.
The new M-2 was designed to comply with the Fédération Aéronautique Internationale microlight rules and US light-sport aircraft rules.
After its first flight in May 2009, the Scout prototype appeared at several Czech airshows and fly-ins.
Two versions are being developed, one to meet the US Light Sport requirement with a maximum take-off weight (MTOW) of 598 kg (1,320 lb) and a second for the European Ultralight MTOW limit of 450 kg (992 lb). Both these MTOWs are less than that of the original Skaut and empty weight are also less. Certification was proceeding in 2010, with the aim of first deliveries during 2011.

As with many homebuilts, a number of builders have made design changes to their HP Aircraft HP-14. In some cases these have been substantial. Andre Krutchkoff built his SHP-1 with his own design of fuselage with T-tail.

Wilhelm Krumsiek was a well-known German aviation pioneer, particularly for the 1912-1914 years.
One machine flew in 1909, and crashed sometimes later.
After having built a second airplane, he became in 1912 chef pilot at the “Zentrale für Aviatik Karl Caspar” (Hansa), and flew with success at a number of competitions (Prinz-Heinrich Flug 1913, duration world record for monoplanes, etc…)

In 1957 Cliff Krum built the Coast Ranger. Krum maintained aircraft for the US Forest Service.
The Jungster II is a follow-up design that grew out of experience with the Jungster I. The intent was to create a plane with the same open cockpit concept but to increase speed and capacity so that it would be an acceptable cross-country airplane. The Jungster II uses the same design and construction concepts except that it is just a little bit bigger, has left the lower wing, behind in favor of a single extended parasol-type wing, and uses a welded steel-tube center section. Engines rated from 85 to 180 hp are used.

The Jungster I was developed as an 8/10 scale version of the famous Bunker Jungsmeister aerobatic airplane. The intention was to capture many of the flying qualities of the Jungmeister in a smaller size. This all-wood, fabric-covered biplane has a swept-back wing design of about 11 degrees to keep the center of lift close to the center of gravi¬ty. It can handle engines rated from 85 to 150 hp and is a frisky single place aerobatic plane.
