Design and development

Designed by Hugo Fuentes[2] (hence the HF in the designation),[2] the HF XX-02 was a conventional, low-wing cantilever monoplane of mixed construction with fixed tailwheel undercarriage.[2] The pilot and instructor sat side by side.[2]

Two prototypes were constructed at El Bosque Air Base, designated XX-02 and XX-02B.[3] Development was abandoned due to difficulties maneuvering at lower altitudes, which in one case, led to a crash in which the instructor was killed while attempting to land after a tight turn at low altitude.

The design was subsequently refined by Francisco Bravo[2] and an improved version, the HFB XX-02 flew in 1958 powered by a Continental O-470 engine in place of the Ranger L-440 that powered the original.[2]
