I am currently training at a very well known school modular school in Europe and there is a guy who did his PPL and hour building in the US and he's struggling to keep up with flying "standards" and the European system. I don't really know what the differences are but this is not the first guy I hear had trouble transitioning to fly in Europe after training in the US. And I was about to go to the US.
By the way, I got my PPL at this school in two and a half months but I had a good instructor and weather on my side.
Maybe Fly-In-Spain?
