Duane's Hangar Ultrababy
American homebuilt aircraft

The Duane's Hangar Ultrababy (sometimes Ultra Baby) is an American homebuilt aircraft that was designed by Duane Patrick and produced by Duane's Hangar of Liberty, South Carolina, introduced about 1997. When it was available the aircraft was supplied in the form of plans for amateur construction.
Design and development
The aircraft is a 75% scale version of the Bowers Fly Baby intended to comply with the US FAR 103 Ultralight Vehicles rules, including the category's maximum empty weight of 254 lb (115 kg). It can have a sufficiently low enough empty weight for that category when a light enough engine is fitted. The Ultrababy can also be registered in the American homebuilt aircraft category.
The Ultrababy features a wire-braced low-wing, a single-seat open cockpit with a windshield, fixed conventional landing gear and a single engine in tractor configuration.
The aircraft is made from wood, with its flying surfaces covered in doped aircraft fabric. Its 27.50 ft (8.4 m) span wing lacks flaps and has a wing area of 121.5 sq ft (11.29 m2). The acceptable power range is 35 to 52 hp (26 to 39 kW) and the standard engine used is the 48 hp (36 kW) Half VW powerplant.
With the Half VW engine the Ultrababy has a typical empty weight of 300 lb (140 kg) and a gross weight of 620 lb (280 kg), giving a useful load of 320 lb (150 kg).

Why this record matters
The phrase “american homebuilt aircraft” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Nov 9, 2025. The linked authority identifier is Q16985925. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1997.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
