My wings have no aero/drag effect

[KerboNerd]

So basically i made some nice wings with ailerons and the only thing keeping me from posting the modpack is the wings not having any drag. Basically when i step off the throttle, i start instantly falling out the sky. And also the wings don't show the "Air effect" when achieving high velocities. Everything around it has drag but itself.

Would help to see the config file

@KerboNerd Try not to make wings with built-in elevons. Make the elevons a separate part. The elevon function will suck if you leave them combined.

Make sure that the model lays flat against the XY plane in Unity. The lift surface and control surface modules demand that the 3D model be oriented a specific way in the production environment. (It's okay if the small end of your wing points to the right and not the left like my example. It just needs to lay flat in this perspective.)

If you turn your wings as they are in-game to be vertical like this and then launch, will they produce lift properly?

Or, if you setup your wings to be as deployed heatshields or airbrakes for maximum frontal surface are and maximum drag, then do they produce lift when you expect that they absolutely would not?

I'm pretty sure your dragAtMinAoA value should not be zero. I don't know how your wing looks, but this value ought to be at least 0.1. Any wing thick enough to be a tank cannot be drag-less at 0 AoA.

Spoiler

And please don't name your stuff "wang." That's not family friendly. Lol.
