hummingbird aims to model fixedwind UAVs and allow their sizing / tuning.
The project is initially forked from mavsim_template_files, completed by sethmnielsen and created by Prof. R. Beard & Pr. T. McLain. These previous templates are the counterpart of the book Small UAV: Theory and Practice written by the same two professors.
I already completed the suggested template project in Matlab and in python. This new version will allow me to go further and test some features of OSS scientific libraries I am involved into (python-control, sippy).
