Regia Aeronautica, Why no use of German planes?

Considering the Clear advantage in quality in the Luftwaffe's aircraft;
Why stick with the home grown production? Why not licence build Fw-190's
& Me 109's instead of Fiat's And Macchi's. While The Germans exchanged
technology with Japan, How come Italy seems to come up short? Would The
Med Campaign have gone differntly if Italian Pilots have had first rate
equipment from their Axis partner?
