I'm trying to decide whether to include drop tanks on my F4F Wildcat. I'm building the earlier version - the one with the red dots in the middle of the American stars and the red and white stripes on the tail rudder. The kit instructions show this version with drop tanks in place but I thought they were a later innovation. Also, assuming I don't include the drop tanks, what should I do with the holes where the pylons attach? I assume I should fill them in but then the schematics in the kit instructions seem to show that there were some sort of holes there to begin with. Does anyone know if this is true?
