[6] The design goals of the CA-2 described a plans-built aircraft for the US FAR 103 Ultralight Vehicles category, including a maximum 254 lb (115 kg) empty weight.
These goals were met and the resulting aircraft has an empty weight of 250 lb (113 kg), when equipped with a 28 hp (21 kW) Rotax 277 engine.
The airframe is of all-metal construction using 2024-T3 aluminium sheet, extruded angles and tubing, fastened primarily with stainless steel pop rivets.
Construction requires normal hand tools, plus a small bending brake and a tube bender.
The control surfaces are made from aluminium tubing, are fabric covered and actuated by pushrods.
