Karnak, whilst the 190A8 has been updated, it is still a smurfy example compared to the real shape of the real plane. It's merely a round tube of a fuselage in-game, but was anything but round in real life. It had nearly flat, sloping, sides, and a flat belly. The joint where the fuslage turned into the stabs was almost square in cross section. It makes creating skins which closely map onto certain shapes of the fuselage and sides nearly impossible sometimes. All 190s suffer in the fuselage shape, a serious deficiency.
The 109E is not so grossly inaccurate in shape, but overall I think it could use some updates. The rest of the 109s look better than the E. The spits, also one of the first new models to be updated, need a massive redo to fix the horrid noses on all of them. They all look like they've got gryphon engines, but should have merlins.
I agree old 3D models first, but I would advocate some of the already-remodeled ones need a second attempt.
