The MacFam Cavalier is a homebuilt aircraft designed by Stan McLeod, developed through a progressing series of models, all using all-wooden construction. The model range includes the SA102, SA102.5, SA103, SA104 and the SA105.[1][2]

Design and development[edit]

The Cavalier was a new design based on the French wooden homebuilt GY-20 Minicab designed by Yves Gardan in 1949. The plans were translated from French to English and modified by Stan Mcleod. The plans were marketed by K&S Aircraft of Calgary, Alberta and later MacFam.[2][3]

The Cavalier is a two seat side-by-side configuration homebuilt that uses all-wood construction. The landing gear may be configured as fixed, or retractable, in tricycle or conventional layout.[4] The wing uses a single box spar covered in 3/32" plywood leading edge skins. The entire wing is fabric covered.[5]

The early Cavalier SA102 series can accept any four cylinder aircraft engine ranging in weight up to 235 lb (107 kg) and 85 to 135 hp (63 to 101 kW), including the Continental O-200, Lycoming O-235 and Franklin 4AC. Later series can use larger engines. SA102 options included wing tip tanks and a third jump seat.[2]
