Ultrababy`s description

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 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.

By 1998 the company reported that 40 sets of plans had been sold and one aircraft was flying.
