Design and development

The Pataplume 1 features a strut-braced mid-wing, a two-seats-in-tandem open cockpit with a windshield, fixed conventional landing gear and a single engine in tractor configuration.[1]

The aircraft is made from wood and finished with doped aircraft fabric. Its 10 m (32.8 ft) span wing has an area of 16.5 m2 (178 sq ft) and is supported by two parallel struts per wing. The recommended engine is a 45 hp (34 kW) 1600 cc Volkswagen air-cooled engine four-stroke powerplant.[1]

While there were no kits supplied for the design, Leger Aviation did supply all needed raw materials.[1]
