The Spacek SD-1 Minisport is a Czech amateur-built aircraft, designed by Igor Špaček and produced by Spacek sro of Hodonin. The aircraft is also produced in the US by SkyCraft Airplanes of Orem, Utah as a light-sport aircraft. The aircraft is supplied in the form of plans, as a kit for amateur construction, or as a ready-to-fly aircraft.

The aircraft features a cantilever low-wing, a single-seat enclosed cockpit, fixed conventional landing gear or optionally tricycle landing gear, a T-tail and a single engine in tractor configuration. Due to its very light weight it can qualify for the German 120 kg category. It complies with the United Kingdom SSDR rules for single seat deregulated microlight aeroplanes.

The aircraft is made from wood, with judicious use of composites, including for the wing spar. Its 6 m (19.7 ft) span wing employs an A315 airfoil, has an area of 6 m² (65 sq ft) and utilizes flaperons. Engines of 24 to 50 hp (18 to 37 kW) can be used. Standard engines tested are the 28 hp (21 kW) Hirth F33, the 50 hp (37 kW) Hirth F23 two-strokes, the 24 hp (18 kW) Briggs and Stratton Vanguard, or the Verner JCV-360 powerplants. The Rotax 447, Hirth 2702, Zanzottera MZ 201, Simonini Victor 1, 2si 460 and Half VW can also be used.
