I'm just a bit curious, not upset, not complaining, just curious.
Even though I took a few months off, I still payed attention to the setups, and while I may have overlooked it, I don't seem to recall having seen the F4U-1A featured in a planeset, even when the F4U-1D was.
Is there a particular reason it does not seem to get included in the Mid War setups ?  Date of introduction to Service ??  Lack of Service on the CV's of the time ??  It was strictly used by the Marines from Land Bases ??
I know I could google all of that info.  I'm just curious why It seems to get left out.
