Greetings young master,
I have only done one myself, and that is for SC3.dll, but the config file stuff is all based on the OAPI anyway. I found that you have to do it by trial and error, by adjusting the parameters until you get something that flies. I couldn't find anything on the web that I could understand, not being an aerodynamicist myself. You could start by looking at config files for other addons. I got the thrust values, ISP, cross section, PMI, rotational drag and all the rest sorted out first, and then messed with the aerodynamics, and then messed with the thrust values and rotational drag again. My ship is a big mother and not at all realistic, so I ended up with these sorts of values (note the attitude thrusters are as powerful as the main thrusters);

I hope you get SOMETHING out of my reply. Real addon developers are probably having fits looking at this. Good luck.
