„RWD-10“ – the Polish aerobatic airplane and „Czajka – bis“ – the Polish school glider

"RWD-10" is a single-engine single-seat high-wing monoplane with a fixed landing gear. This plane was designed by engineer Jerzy Drzewecki in 1923 and manufactured by “DWL” (Doswiadczalne Zaklady Lotnicze – Experimental Aviation Workshop) in Warsaw. It was used in aero clubs for training pilots in high acrobatics. It was recognized as the best aerobatic plane, ever built in Poland. All 23 manufactured examples were still flying in September 1939, when they were destroyed by war storms.

"Czajka" was A. Kocjan's first construction, realized in 1931. "Czajka-bis" was her fourth modification, which took off in 1936. More than 150 gliders of this modification were produced in Poland. "Czajka-bis" wing - one spar, front covered with glued plywood, behind the spar - with fabric. The wing is supported by spares from a steel tube. The keel and stabilizer are covered with glued plywood, the stabilizer supported by steel tube spares. The steering plates is covered with fabric. The fuselage gondola is made of glued plywood, with an ash slide at the bottom, cushioned by rubber balls. The tail truss is two T-shaped pine spars, stiffened with spacers and connected in the middle with a steel tube. In 1940 the liquidated LAK received two such gliders, which were flown in Aukštagiriai and Kulautuva in 1940-44.

Small and simple, well designed (there is a simplified detailing of the cockpit equipment) models of aerobatic airplane and training glider, which can be perfectly put together even by a modeler with little experience, working under the supervision of a more experienced colleague. With some effort, the glider model can also be made to fly. Antiquarian publication.
