I will probably do an F4F template when I've finished all the F4F skins I'm planning and once at least one has been deemed OK by HTC. Probably a month or two away yet.
The F4F has lots of variations for the different US and FAA versions, what with 2 different engines, several cowlings, folding/non folding wings, 4 guns/6 guns. The template will have all these as layers so you can pick the combination you want.
