Anybody helps me. How to place wheels on ground. My model is floatting in the air. I know that I have to edit aircraft.cfg, but contact points has many points. I don't know what means witch point. Does exist a tutorial? Any text to understand that points?

There is a tutorial in the "help" section of SimV that helps you better understand the concept of editing the dynamics and contacts of any addon. Just go to this link:

It's located in the bottom-right corner of the list.

Just remember that the tutorial is quite big and if you need further understanding just drop us a line here in the Aircraft & Design section and we'll be glad to help.
