Hi @ejohnathon!
I have had a look at all your models and what I would definitely do is to increase the size of your bounding box as your domain is way too small! Also add layers to your NACA profiles.
A good tutorial would be that one right here: CFD Master Class - Session 1
Also have a look at some NACA simulations in the Public Projects section that can help you to set up your project. I am sure you will get pretty good results if you increase the size of the domain as well as adding layers.
Cheers and good luck!
