I think they used them because they took them from the Italians and would use anythign that was decent, but not because they thought the Me-109G and Fw-190's could not.
Wow lanc, shows that youve done lots of research on your Italian planes, because if you could be arsed to do a little look around youd see that they werent all "rubbish" compared to Allied designs.
Wright Flyer with a couple of .50 cals won the wings would make for a great ground attack aircraft, as it operates best at an altitude of around 3 - 4 feet
They may have been some of the best that the Italians made but compared to Me-109's and Spitfires they would put a fight at best. Against a Fw-190 or P-38 they stood know chance.
