I've been thinking about the markings on this one and there's a bit of an issue. Normal FAA practice for the underside of the wings was to have a medium-sized roundel outboard and then a really big serial number inboard of it, with one of the latter being reversed so it was readable from the front. The problem with the Skyhawk is that the wingspan is short and very obstructed by pylons, big drop tanks and the undercarriage fairings. Assuming that the roundels take up all the space outboard of the outer pylon, then to fit the serials in between there and the wing root, they have to be pretty small, they're largely obstructed by drop tanks on the inners, and they're messed up by the undercarriage fairing and doors.
A few other options occure to me:
1. The "by the book" version, but split around the u/c fairings. This would still be blocked by the tanks.
2. Single code, small enough to fit between the u/c fairings.
3. Same as 2, but much larger, to the point where the first and last digits are outboard of the fairings.
4. Single code but on the flaps. This is least likely to be blocked, but the size is limited.
What do you folks think?
