Skodovy Zavody had a controlling interest in the Czech Avia company and in Ceskoslovenska Letecka Spolecnost, the Czech airline. Parent company has also made cars, firearms, etc.
Zaschka Helicopter
In 1928 Zaschka carried out experiments with a two-rotor helicopter at Tempelhof Airport in Berlin.
“His [Engelbert Zaschka’s] plane, the first helicopter, which ever worked so successfully in miniature, not only rises and descends verticially, but is able to remain stationary at any height. Herr Zaschka is fully aware that the perfection of his invention will be the greatest forward step in aviation since the Wright brothers made their historical hop. As he pointed out, the danger of flying would immediately be decreased by at least 80 per cent, since four fifths of the accidents in flying occur either in the takeoff or in landing. […] A motor giving thirty to forty horsepower is installed in Zaschka’s present experimental machine. It is so delicately adjusted that he has been able to keep the plane at a height of several feet above the ground, with no movement either up or down.”

YumashievYu-1
AB Yumashiev built the Yu-1 glider in Kiev in 1925. Designed as a training glider, it was developed with a view to participating in the competitions that year in Crimea.
The Yumashiev Yu-1 (Russian: Юмашев Ю-1) was conceived as a single-seat training glider. It was conceived as a high-wing cantilever monoplane. The wing, with the Pr-426 profile, had a double spar structure and a trapezoidal shape in the plane.
The fuselage was built with a plywood frame structure and had an aerodynamic wing profile shape (curved at the top and flat at the bottom). The front 2/3s were covered in sheets of plywood. The tail section was covered with fabric.
The Yu-1’s offset rudders featured a rounded shape.
The landing gear featured a conventional wheeled structure, but for record flights they could be concealed within the fuselage. For training flights they were kept exposed.
First flying in September 1925, the Yu-1 glider was entered in the III National Sailing Competitions held in Koktebel in 1925. On September 30, Yumashiev managed to stay in the air in this glider for 1 hour and 30 minutes, which was a national record.
A day later, on October 1, Yumashiev at the controls of the Yu-1 would achieve for the first time in the USSR, a long-distance flight taking advantage of thermal currents. This flight recorded 4800 meters and was considered a national record, because in the competitions the longest flight value would be 24.4 km, reached by the German Nering on his “Consul” glider. For this flight Yumashiev would receive the award for second place in the competition.

At the Third National Flying Competitions in Koebel, held in 1925, one of the best Soviet gliders was the Yu-1 designed and built by Yumashiev. This glider demonstrated staying in the air for an hour and a half and reaching 375 meters in height. These results were national records.
He set six world records (including two as co-pilot): in 1936 two flight weight records in the Tupolev TB-3TB-3 and in 1937 two flight distance records aboard the Túpolev ANT-25 as a crew member of MM Gromov.
