Thanks for the kind words John (@johnb), Spiros (@fiveten), and George (@gblair). I have a bit of repair work to do on one cowling and the scoops still need to be added.
I've been experimenting to see how I might improve the flap track housings. Making a mold and casting duplicates is one option, but with this small of a part, it would be extremely wasteful to cast one track at a time and very inefficient and not worth the effort to make 5 mold plugs to cast five at a time. Or I could leave them as is and repair the two broken ones, however, they are not very well done. So I was looking for another option. It occurred to me that I might be able to use gravity to aid me here.
Using some .030 x .030 square cross section styrene, I cut off some pieces longer than I needed and dipped them in three different liquids. Black CA, Micro Krystal Clear (PVA glue), and Ammo Mig Ultra Glue. My thinking was that they would naturally form into a small tear drop shape on the plastic. I am trying to duplicate this part.

1. Flap Track Housing I am trying to duplicate
The Ultra Glue is too thick and didn't work at all, so I immediately rejected that. I might have been able to form it into shape, but they would have been inconsistent and at that size, difficult to manage.
The Black CA was tried next and the first effort yielded good results. Depending upon the angle of the part as it dries, this tear drop shape is slightly different. I tried a second one and held it at a different angle. The Micro Krystal Klear also seems to work, but it is harder to control the amount of glue on the part. It appears larger in this photo because of that. It might shrink a bit after it dries and be okay.

1. #1 Black CA at a different angle than #2. PVA has the best shape, but too big. #2 Black CA is my choice for now.
Once these are dried, I will snip them to length and glue them to the wing. Given the inherent fragility of such an arrangement, it will have to be done after painting and touched up. Should be possible to do that using an airbrush if I am very careful. I'll test one ahead of time to make sure they look okay on the wing, but I am hopeful.
