I have several ARFs I have been happy with for several years until I read this thread. A couple of them have glaring insignia errors once you really look at them. Happy to say the insignia on TF Corsair .60 ARF looks OK (without doing a bunch of measuring and really close inspection).
Regarding full scale, I happen to be looking at some film clips on the "Critical Past" website of flight operations on Guadacanal in May, 1943. One clip showed some Corsairs and Wildcats (if I remember right) with insignias on the top of both wings. Wouldn't have even noticed that detail without reading this thread.
