Nice, but that centerline drop tank is way too far aft. The forward attachment point appears to be located where the aft attachment point was located on the real F4U-1A/C/D. Definitely not what we would expect from A2A these days.
Could it be the perspective from the screenshot making the tank look too far aft? From this perspective too it looks like if the tank were moved forward to where you thought the aft attachment point should be, then the fwd attachment point would be under the engine cowl. I know Milviz used high quality 3-view drawings so I'm sure they put it where the tank was showing on the 3-views.
I do agree the engine seems to be a little too far back in the cowling, and I notice the numbers are backwards on the landing gear doors attached to the struts, almost like they mirrored the starboard door which would make it backwords in the UVW mapping.
