I think it’s community dependent. I don’t recall anyone “missing” their primary trainer or pretty much even talking about bugsmashers after primary.The T-6A can pull 7gs. It has 1100hp. The AF taught us to do formation aerobatics. It's a shit hot little plane. But I've also seen JOs standing around in the wardroom talking about how much fun they had flying a 172 around that weekend. Any good red blooded pilot is going to miss a plane they used to fly because they're all fun in their own way. I'd buy a T-6 or PC-9 one day if/when I have the money!
