144th WWII fighters

Hello again! Well this is some work in progress pictures I have taken of some 144th scale WWII fighters that I have been working on. They will be for some dogfight games about the air battle over the Philippines in 1941-42. I am trying to decide if I want to paint the panel lines in a darker color (like dark Olive Drab) or mark them with black ink. There is an advantage and a disadvantage to both methods. I still have to make a final decision on what I want to do.

Two of the models will be P-35A's for the USAAF and the other is for a P-26A for the Philippine Army Air Force. I will work on P-40's for the USAAF and Japanese airplanes later.
