[1] St Croix Aircraft principals Chad and Charles Wille had built several Pietenpol Air Campers starting in 1941.
The St Croix version of the Pietenpol Aircamper is longer and heavier than the original design, with slightly more wingspan.
[1] The St Croix Pietenpol Aircamper features a cantilever strut-braced parasol wing, two-seats in individual tandem open cockpits with windshields, fixed conventional landing gear and a single engine in tractor configuration.
The standard day, sea level, no wind, take off and landing roll with a 40 hp (30 kW) engine is 750 ft (229 m).
[1] The design was later further developed into a biplane, by adding lower wings to the parasol Aircamper, resulting in the St Croix Pietenpol Aerial.
