The HB Flugtechnik HB-207 Alfa is an Austrian two-seat light training and touring monoplane designed and built by HB Flugtechnik and was made available as a kit for homebuilding.

[1][2] The Alfa is a low-wing monoplane made from aluminium, with some composite parts, powered by a 110 hp (82 kW) VW-Porsche HB-2400 G/2 flat-four engine driving a five-bladed variable-pitch propeller.

The five-bladed propeller turns at just 1500 rpm and is noted for its quietness in flight, producing only 57 dBA.

The Alfa has room for two in side-by-side seats in an enclosed cockpit with a sliding canopy for entry.

[1][2] The first aircraft to fly was a retractable tricycle landing gear variant, the HB-207RG.
