ENMASA Beta

The ENMASA Beta was a Spanish air-cooled radial engine of the 1950s. A copy of the American Wright R-1820 Cyclone, the Beta was the powerplant of a number of post Spanish Civil War aircraft, including the Spanish version of the Junkers Ju 52 transport, the CASA C-202 Halcón and the Hispano HA-100 trainer.
