Aero A.25

The Aero A.25 was a biplane military trainer aircraft developed in Czechoslovakia from the Aero A.11 reconnaissance-bomber and generally similar to the Aero A.21 night trainer.
Some A.25s were powered by the less powerful 134 kW (180 hp) Breitfeld & Danek Perun I engines, in which case they were designated Aero A.125.
