Anyone know of some aerodynamics simulation software? Something to simulate the characteristics, virtual wind tunnel sort of thing, if I want to build my own wing/body for a model RC plane? I've got several of variable merit. Remind me in a day or few if you aren't well served by what you find. If you do get some good recommendations do please tell us about them.
