I didn't fly yet the a10cII so I would not know if there is a difference now, but I can tell you that the original one was indeed way off. I noticed it immediately after purchasing it and going for a quick flight back in 2014. When you fly enough IRL you can tell when something is really off despite not having flown the actual platform. You can tell by the wing area, weight, wing shape, speed, etc. Those things let you know when something is incorrectly modeled. Then a couple of years later an actual warthog pilot said that exact same thing, plus that the engines were too weak, which as far as I know ED hasn't changed yet. EDIT: As far as I can see in the A10C II videos it seems that it has improved a lot, and the module is a blast!
