What a question It's ok if you don't download the additional artwork for cockpits, you get the default image. Check the download list on the FH web page for the upgraded/updated/correct/new artwork cockpits. Enjoy.
Sorry, guys, Here is quick fix: http://flyingbarans.ru/files/wb/def.rar Download it and unpack files right over existing ones into your FHLauncher folder. Thx. correction: problem is fixed now. I was upload correct FHInstaller.
J2M does not have own cockpit. F6F is taken as most similar one. btw, artists welcome to create cockpit art for J2M. def*.fh files must overwrite the ones you have on your puter. in my situation the folder is C:\Warbirds2773\FHLauncher1.67\ in your situiation a folder may be different, depending on where you installed warbirds and fhlauncher into. p.s.Beaufighter's own cockpit is on the way, in two weeks.
those who have problems placing def*.fh files, pls redownload fhlauncher (def*.fh files injected into and placed automatically)
