The Macchi MC.202D, an only one version of the “Folgore” with only an oil and glycol radiator under the engine. The aim of this modification, make late 1941 and based on a Series III aircraft, the MC.202 “Folgore” military registration MM7768, were the removal of the complex and vulnerable piping. But the effect of the large radiator under the nose was the strong increase of the aerodynamic drag and this attempt was therefore abandoned. Victor Sierra

MC.202D

A 4th Stormo Italian Air Force’s Macchi MC.202 returned to his base, likely in Sicily after a mission over Malta, without the right half horizontal plane detached after a sharp recovery from a high speed dive: an event experienced by some MC.202’s pilots during the first fighting with this aircraft more performing of the Fiat G.50 and the MC.200. At first this event was attributed to a structural “weakness” of the tail plan which was strengthened, but this phenomenon continued to repeat yourself and the pilots, in the main by intuition, learned to “pace the controls”, in particular the stick, during certain manoeuvers as the recovery from an unusual asset or from a sharp high speed dive. In reality the Italian pilots experienced a series of aerodynamic phenomenon to them still unknown (but also to may Italian aircraft designers) as the compressibility and the flutter. A great and dramatic problem of the Italian aviation during the years immediately before and during the war was the gap between the theoretic experience elaborated in research centers as Guidonia and their transfer to the practice. In other words the knowledge today within of a Sunday aviator’s reach at this time were in good part unknown by the Italian military pilots. Victor Sierra

An unknown phenomenon 

In an attempt to improve performance of the Macchi MC.200 “Saetta”, his designer Mario Castoldi created the MC.201 designed around the new Fiat radial engine 1,000-HP A.76 RC-40 but the prototype (military registration MM436) flew, August 1940, with the same 870-HP Fiat A.74 RC 38 of the “200”. At this time the project “202” with the powerful German engine DB601 were already advanced and the MC.201 was abandoned. Victor Sierra
