First is with the Ta152. The little light/button things on the console infront of the joystick are floating about 2 1/2 inches in mid air from where they're supposed to be.
(Correct placement, on the Dora)

(Incorrect placement- as you can see from the multiple angles, they are floating)


Also, there is a graphical error on the Bf.109F. The panel under the windscreen on the right side was not a glass panel as it was on the left side, but in Aces High it is. On the real Bf.109F there was a metal panel here with a hole in it for shooting out signal flares.
(the hole is covered in this example, but it clearly shows the metal panel)

Also, the MG131 gun ports on the Bf.109G6, 14 and K are incorrect. They were much more angular on aircraft equipped with the MG131.
In-game-

Proper-

Couple more.
One last thing, graphically- although I will not outright doubt the dimensions, something about the dimensions, or at least the shape, of the supercharger intakes on the 109 series seems incorrect.
Lastly, a request- the Bf.109G-6 we have (with Gallandpanzer and standard frame canopy, standard sized vertical stab) was built in Autumn, 1943, and included Werk Nummer production batches
20000, 22100, 26000, 27000, 140000, 160000, 161000, 162000, 163000, 164900, 165000, 166000, 410000, 411000, 412000, 413000,
440000, 441000, and 442000.
About 80 aircaft in Werk Nummer block 20000-20800, built at WNF, were Bf.109G-6/U4's, and aircraft in Werk Nummer block 440000-441000, built at Erla were also Bf.109G-6/U4's. U4 denoting that the aircraft was equipped with the MK108 instead of the MG151/20. Thus we should have this option in-game.
