Just incase you missed it. The 0.20.1 version of the SDK says it updated the "How to create a flight model" section. (we are now on 20.2). ASOBO never really emphasized what they did. There is some really good stuff there now. Suggest if you have issues like me in understanding the flight model parameters, this is a good place to start. Especially the "The Flight Model" part. (Basic Aerodynamics, Geometry and Fine Tuning).
This is excellent stuff, I just want to say well done. "More of this". Helped me understand things better. Very clear and not too many typos ;-)
keep up the good work on the SDK. Thanks
