In 1916, the French Air Force issued a specification for a new plane, capable of filling reconnaissance and light bomber role.
In response, Emil Samlson submitted his design, later known as Samlson 2.
This design won the trials and after few improvements was put into service starting at 1917. It was produced in two versions – 2A2 as a reconnaissance plane and 2B2 as a light bomber. The Samlson 2 entered the service in our Air Force in 1919, when 49 planes of 2A2 versions, manufactured by Latécoere company, were given out by France. They served until 1923.

The Lockheed Vega was a single-engine fixed-carriage high-wing monoplane designed and flown in 1927 by the Lockheed Aircraft Company. Thanks to its extraordinary performance in those days, this machine went down in aviation history with many record-breaking flights. Names associated with Vega include Amelia Mary Earhart (the Lady Lindy machine, the first woman’s flight across the Atlantic), Wiley Post (the Winnie Mae machine, the first flight and solo flight around the world), or the polar aviators George Hubert Wilkins and Carl Ben Eielson (the first flight across the Arctic). The yellow-red Shell Oil Company machine was also piloted in the 1930s by the later US General James Harold “Jimmy” Doolittle.

Finally, I can present you another representative of my favorite air force.😉 I used Hasegawa plastic parts with a lot of my own 3D printed stuff.

The Mitsubishi Ka-14 was a prototype of the famous A5M Claude, a predecessor to the even more famous A6M Zero. Its most distinctive visual feature is the inverted gull wing with beautiful elliptical wingtips (however, the inverted gull shape was abandoned in the production version of the A5M), and in the case of this particular prototype version, the interesting modified engine cowling.

The Nakajima Ki-43 Hayabusa (Oscar) was one of the most numerous Japanese WW2 fighters, a land-based contemporary of the more famous Mitsubishi A6M Zero. 

In 1919 Ing. Beneš and Ing. Hajn designed and in 1920 built the BH-1 Exp (Experimental) low-wing, experimental monoplane concept under the banner of the new Avia factory. And thanks to previous attempts on models, the work was successful the first time and the concept proved itself. It was a pioneering concept for its time, which fully proved itself in the category of training and sports aircraft.

In 1927, the Letov factory modified the Š-20 fighter plane of designer Alois Šmolík with a Škoda H-S 8Fb in-line engine for a Walter Jupiter radial engine (Ghone-Rhone license according to Bristol Jupiter) with an output of 480 HP (353 kW). This is how the unique Š-20J was created.
