      Hi, I recently flashed my Sentinel drone, and apparently, the files under /data/px4/params are missing.

      How can I recover the following factory default params files for the Sentinel drone:

      parameters_gyro.cal
      parameters_acc.cal
      parameters_mag.cal
      parameters_level.cal
      

      I have tried calibrating the Compass using QGC, but it doesn't perform accurate calibration, and unless this issue is resolved, I cannot fly up the drone.

      Please help.

        @SMRazaRizvi What do you mean that compass calibration is not accurate?

          I mean, even after calibration, my drone constantly drifts toward the back. Any clue?

            @SMRazaRizvi The compass provides heading information. Having a poor calibration on the compass wouldn't cause the drone to drift.

              I see. What can be the reason then?

                @SMRazaRizvi Do you have any trim settings on your controller? The level calibration could also affect

                    have you posted your PX4 logs to logs.px4.io for analysis?

                        @SMRazaRizvi Can you please share so we can try to help you? The logs should help diagnose why it is drifting
