Flight characteristics with the rotating wing-tip panels were not as expected so a conventional vertical fin on an extended rear fuselage, and ailerons constructed from fabric-covered Duralumin on the outer wing traling edges, were added after initial flights.
Eagle Model A-101: Improved version of the A-1, with ailerons on the lower wing and other improvements.
Even during take-off from Istres on 18 October 1932, Marmoz noticed the aileron controls were slack, the ailerons themselves vibrated and there were large oscillations of the wings, with amplitude as much as 1 m.
The hydraulic actuators driving the ailerons were only one inch (25 mm) thick to fit into the available space and were known as Piccolo actuators because of their resemblance to this musical instrument.
The aircraft was seriously damaged in an attempted take off from Frensham Pond and then rebuilt as a landplane once again, fitted with ailerons rather than wing warping.
