The González Gil-Pazó GP-1 was a single-engine, two-seat open cockpit training aircraft, built in Spain in the 1930s to compete for a government contract.

This "supremely elegant" aircraft, with two open cockpits and a trousered undercarriage was reportedly somewhat like the Miles Hawk Major in appearance.

[1] The competitive trials, against the Loring X, the Hispano HS-34 and the Adaro 1.E.7, assessed the Gil-Pazó GP-1 as the clear winner, so in 1936 González Gil and Pazó received an order for 100 aircraft.

None of these had been completed by July 1936 at the start of the Spanish Civil War, and with rebel forces approaching Madrid in October, AISA retreated to Alicante.

In January 1936 Ramón Torres and Carlos Coll set a record with their flight from Barcelona to Agadir, Morocco in the two-seat GP-2.

The single-seat GP-2 was flown by Lorenzo Richi in March 1936 from Madrid to Bata in what was then Spanish Guinea at an average speed of 187 km/h (116 mph).

[1] About thirty of the forty GP-1s built at Alicante were captured by the Nationalist forces, given military serials and incorporated into Grupo 30.
