The idea is to eventually update all my existing skins to AH3 standards, but given there were 310 of them at the time of the last AH2 skins update its going to take a while. Once I have updated one of a particular subject it takes a lot less time to do others, so I am concentrating on either updating or doing a new skin for each subject.
The pilot can be edited for all AH aircraft but usually only bother if its a different nationality, i.e a Japanese C-47A skin. I'll bear in mind what you said about Vraciu's white helmet and it should be pretty easy to change it.
