After thinking about this a little more, I think I need a combat plane in addition to the Sopwith Baby I'll be using for intercept purposes. A seaplane with floats is going to get eaten alive in the combat sessions after the escort missions.
Can I get a Baby Brit done up in this color scheme?
Green for the top of the wing and hstab, and yellow for the bottom.
Use the standard US roundel on the upper and lower wings.
And this version of the Indian Head insignia.
