In this video I go through:
1. The theory of Betaflight PID tuning
2. How to find your maximum comfortable D gain
3. How to get a great tune without blackbox logging
4. How to use PID toolbox to find the right P gain
5. How to tune feedforward for great setpoint tracking

This PID tuning approach is similar to that used by @UAVTech . I didn't invent how to tune PID controllers but I hope that this explanation is helpful nonetheless.
