Bit of a sweeping generalisation about American aviation magazines, Stampe. Undeniably, some once great U.S. titles are, like 'Pilot', in decline editorially, but there's still some fineaviation journalism on the other side of the Atlantic. Try 'AOPA Pilot' or 'The Aviation Consumer'. At the heavier end of things 'Business & Commercial Aviation' sets very high standards of accuracy and authority, and 'Air & Space' is for my money unmatched anywhere for quality writing and illustration.
