ASJA SK-10 / Raab-Katzenstein RK-26 Tigerschwalbe

Raab-Katzenstein RK-26 Tigerschwalbe, was a German twin seat biplane trainer aircraft designed by Gerhard Fieseler during 1928.

In December 1930, Fieseler was invited by the Swedish Air Force to present his aircraft for the Swedish aircraft manufacturing company ASJA.

Flygvapnet was in need for a new trainer, and the RK-26 was an interesting aircraft.

Fieseler had recently won a world aerobatics championship with an RK-26.

ASJA then decided to buy one aircraft.

It was tested with different engine configurations by Flygvapnet, who later ordered 25 aircraft from ASJA.
