I read an article some years ago about the RE 2000s received by the hungarian Air force directly from italy. They were scathing in their assessment of them, the guns suffered continual jams, the wings fluttered very badly in a high speed dive, but the thing that I remember most were the desription of the fuel tanks. they apparently leaked profusely, allover the wings, so the craft were forced to fly into combat, covered in fuel.
MAVAG, the Hungarian aircraft concern, eventually undertook extensive modificatiuons, and produced the lions share of "Hejas" (the Hungarian equivalent of the RE 2000. This modified and re-equipped version was actually quite effective.
I dont know if the duds were just those 30 or so sent to Hungary, or if the type was generically suffering from poor QA. However, on the assumption that it was a generic problem, I would not support it as being better than the MC200, which I have also read had very high production standards.
BTW is it true that the RE2000 was basically an upgraded and re-designed P-35????
