[1] The F.K.27 was a sesquiplane two-seater with side-by-side seating staggered en echelon to starboard.

The two bay sesquiplane wings were arranged conventionally, with the lower mainplane attached to the bottom of the fuselage and the upper mainplane supported on cabane struts above the fuselage and solid built up inter-plane struts.

The fixed under-carriage consisted of strut supported main-wheels and a sprung tailskid at the rear extremity of the fuselage.

Powered by a 200 hp (149.14 kW) ABC Wasp II, the F.K.27 was also aerobatic.
