Design and development
In March 1946, Edouard Joly and Jean Délémontez formed the Société des Avions Jodel to supply kits, materials and plans to allow homebuilders to construct an ultralight monoplane designed by Délémontez and named the Jodel D.9 Bébé . The D9 was a wooden low-wing cantilever monoplane with a single-seat open cockpit and a fixed tailskid landing gear. The wing had an inner section of parallel chord and no dihedral, joined to outer tapered sections with strong (140) dihedral,. This became a standard feature of many subsequent Jodel models. The prototype D.9, registered F-PEPF first flew on the 22 January 1948 flown by Edouard Joly.
The D.9 was powered by a single 25 h.p. Poinsard flat two-cylinder engine, the D.91 by a 34 h.p. A.B.C. Scorpion flat-two and the D.92 by flat-four Volkswagen engines of either 26 hp (19 kW) or 45 hp (34 kW) The D.93 had a 35 hp (26 kW) Poinsard, the D.97 a 32 hp (24 kW) Saroléa Vautour and the D.98 a 25 hp (19 kW) Ava 4A-00.
Although designed for amateur construction and built in large numbers, it was also built commercially and the Wassmer company built 12. Plans were also sold by a number of companies including Falconair in Canada. Over 800 plans have been sold and over 500 aircraft have been built by amateurs and flying clubs.
Ben Keillor translated the French kit plans to English in 1959, and constructed and demonstrated a D9 in Canada and America. The design was further developed into the two-seat Jodel D.11.
Jean Delmontez scaled up the D.9 to produce plans for a three-seater powered by a 75 to 85 hp (56 to 63 kW) engine, but was persuaded by SALS (the Light Sport Aircraft Service of the French Government) to build the two-seat D.11 to provide training aircraft for French aero clubs using the wing of the D.10.
