Yeah I was also under the impression that this would be a free upgrade. At a push I might stump up a modest upgrade fee but 50 bucks? No thanks. I'm sorry CaptainSim, I used to be a supporter of you guys, but the recent predatory pricing approach is turning me off big time which is a real shame. Your legendary Mig-21 I purchased back in 2002 was my first payware add on IIRC...
