Only difference between the Corsairs damage model is the F4U1 and F4U1A have fuel tanks in the wings as well as the main. All the other Hogs have a single main in the fuselage with eternal drops. It seems the F4U1/1A aren’t as vulnerable to fuel leaks depending on fuel load out as the wing tanks can be a nice reserve. On the other side though, those wing tanks aren’t self sealing, which may make the Hog more vulnerable to fires.
