Show HN: I wrote a multicopter simulation library in Python

There are many simulation libraries out there. For example AirSim using Unreal Engine, several implementations in Unity3D, Matlab toolboxes. I wanted a simple hackable codebase with which to experiment.
So, I wrote this. Propellers, motors, batteries, airframe are their own components and can be mixed and matched. The code lets you create any number of propellers, and an optimization function learns a PID controller for that vehicle. Additionally, there are convenience functions to visualize in 3D and sensor measurements.
Please let me know what you think :)

Thank you for linking to other resources. I will take a look at them.

Gymnasium w/ MuJoCo or similar would probably be most worthwhile in terms of research,

There must be fluid simulation in MSFS and XPlane because they model helicopter flight characteristics.
I don't think either model things like solar thermal effect upon wings' material properties yet.
