Type 1 was a very low power French single seat aircraft built in 1934 to a target price of 20,000 Francs.

Its horizontal cylinder-shaped nose had the 15 kW (20 hp) air-cooled Poinsard flat twin attached to it externally.

Immediately behind the engine, where the upper half of the fuselage was entirely glazed, was the 600 mm (24 in) wide cabin, with two more windows aft.

[1] The Botali's landing gear was simple: on each side a wheel was mounted on the apex of three steel tubes, two from the lower longeron and a third to the nose framework about halfway up the fuselage.

Type 1 was successfully demonstrated at Orly by Cressaty, flying along with several other French light aircraft in very wet and windy weather; a Mignet Pou-de-Ciel took the honours.
