So after a worse than horrible installation experience what with all the undocumented Steam nonsense etc, very pleased with the trainer edition. I got a very very old G series edition decades ago and now thought I'd try the latest while I'm snowed in. And would you believe, the old Futaba Interlink Plus USB controller works perfectly. I really wasn't expecting that. Back to the installation, I don't know why RF don't put the trivial amount of effort into providing instructions (the link on the Tower site where I bought it is a 404); it's a very small amount of effort - a couple of paragraphs - for a great deal of customer satisfaction (witness all the posts here about install issues).
