In 1960, under the direction of Stelio Frati, Procaer built the F.400 Cobra, a two-seater jet powered by a Turbomeca Marboré II.
Construction of Cobra is mixed wood and all metal and the outer coating of birch plywood covered with a pure aluminum foil bonded over the entire surface.
The prototype was destroyed during its return from the Paris Air Show to Italy.
A second prototype, with four seats and a Marboré VI, the Procaer F-480, was maintained in the collection of Charles Bezard.
