That physics package has more bugs than a dog has fleas, but I couldn't remember how it was done. I have a project that I have in mind that could use a similar setup, but I hope to make it load without 30 or so warnings.
Flight in RF6 stinks in comparison to G3, which was stable at high speed. But I'm not working on an AV for this. All I really wanted was a close look at the physics, so that I could start over with another model but apply the concept to something correctly modeled and avoid the various warnings.
I don't think you can ever fix this one with just an AV, because needed component names are not in the 3D model. To remedy that you would need to have the original source model.
