I would second the idea of shaking airframe. That's one of the last holdouts that RoF has a clear advantage in. I could live without animated engine or gun cycling effects if we could just get a shuddering airframe.
Its not a shuddering airframe, but Hellshade's Turbulent Skies mod does add more to the feeling of flight with increased wind turbulence that bounces your plane around a bit more and makes it harder to keep a steady aim on your opponents. Try it with a test pilot and see what you think.
