Do you want to do a Britt scheme or a US scheme? How about one with a Red fuse or a PC 10 fuse with a Red Alligator on the side? The Brittish wern't too colorful compared to the Axis planes so you don't have as many different ones to choose from. Do you have any books? The Windsock data file on the SE5a is a good one as is the Squadron publications The SE5a In Action. I do have a lot of Info on the SE5a but I don't have the training colors.
