I downloaded your file and extracted it. Looking at the class, payload and all payload files the F4U-1 was left out. I added it just like I did when using DCG with the unified installer versions of the mods so it would be available in DCG. Below are the lines I added to the files.

Note below when it appears in this forum the spaces between columns is different than what it should look like in the actual file. Easy enough for you to fix with a space bar when you paste it to the correct file.
