Data of hover with LPS and PID

Hello, I made a stereosystem with 2 PS-Eyes and implemented an own Kalman-Filter and an PID-Positionscontroller. It would be nice if someone could give/show me his/her reference-data from hover with the PID-Controller/EKF implemented in the official realse on GitHub in combination with the LPS. I al...
