I had a share in a C150 for several years, and flew it quite a lot. And I agree that the flap system is horrible. Looking up to see how much flap you've got on final, when you should be looking at the runway, is awkward to say the least. And putting the flaps up when doing a go-around is really awkward! It was nearly as bad after a few years as it was at the beginning. Recently I flew a C152 for the first time for a few years, and the flaps were so, so much easier to operate.
I have no idea if this relates to the accidents, but if I was a new PPL finding landings difficult the C150 certainly wouldn't make it any easier for me.
