F.4 Rondone
The prototype Rondone (Swift) was built at the C.V.V., Milan, but production aircraft were built by Societa Aeronautica Italiana, Ing. A. Ambrosini & Co from 1951. The F.4 was a two-seater powered by a 65hp Walter Mikron but most of the production batch of ten were fitted with Continental C-85 or C-90 engines. One F.4 Rondone achieved a world record speed of 169mph over 100 km on 90hp, though the more normal maximum was about 155mph.
The F.4 was developed into the three-seat F.7 Rondone II in 1954. Only the aircraft have been traced, the earlier 'missing' c/ns presumably belonging to other Ambrosini production or simply not used.
F. 7 Rondone II
The three-seat version of the F.4 featured additional cabin windows in the 26" longer fuselage and a Continental C-90 as standard powerplant. Several were later fitted with 100hp O-200 engines, one with a C-85. Ten Rondone IIs were built by Legnami Pasotti S.p.A. and one further example was apparently converted from an earlier F.4.

Регистрационный номер: I-ADRE [2] The conversion of I-ADRE to F.7 standard is more clearly seen in this shot at Croydon from Malcolm Fillmore. Compared with I-ADRL this has a taller, rounded fin, no dorsal fillet and different rear cabin window shape.

Регистрационный номер: I-ADRE [2] Enough of I-ADRE is visible to show that it has the extra cabin windows of the Rondone II, though it appears to have retained the more rounded rudder of the F.4 from which it was rebuilt.
