I want to model a damaged airplane and implement new controller on it, from the literature, it seems that NASA's GTM model is the best way to do this, I have downloaded the open source model but I can't find any tutorial. If you know a reference for this please share it with me.

Also if you know a better way to carry out such task, instead of using NASA's GTM model, I would be glad to hear it.

thank you for your time.
