He was being sarcastic...
And, to be fair, it's been a while since I've flown any of them, and it might not be their flight dynamics that disappoint. There is something, though, in those aircraft that leaves me wanting more. Maybe it's the lack of system depth, maybe its something else. I probably should have just said that something about them doesn't satisfy and left it at that. It could well be that their flight models are the best part of them. The GeeBee is certainly a beast to handle and fly, which seems faithful to the original.
I think I'll take a flight in several of them again and see what I think.
