In the early 1930s, Spanish pilot and engineer Julio Adaro began developing a trainer aircraft for a competition held by the Spanish Air Force.
Adaro Chirta Design and Prototype
The prototype aircraft, designated Adaro Chirta, was completed in 1934. This model was a two-seater sesquiplane of mixed construction with dual controls, powered by a 105 hp Walter Junior engine with a two-bladed tractor propeller.
Competition Entry and Outcome
That same year, the sole example of the aircraft, which received the military designation 1.E-7, participated in the competition alongside the Gil-Pazó GP-1 and the Hispano E-34. Although it demonstrated its capabilities, it only secured third place and, consequently, did not enter serial production.
