      Hi,
      Problem # 1:
      I am trying to fly the ModalAI Starling in "Position" flight mode, but it's continuously losing it's position while flying in "Position" mode and going to "Altitude" flight mode automatically.

      Problem # 2:
      I am experiencing RC Loss (see log # 2 below) while the drone is approx. 3 meters away from the drone.

      Can you please tell us how to fix these issues and why these issues are appearing?
      We just bought the drone last week.

      Below given are the logs of the flights with problems:

      Log # 1 - Drone is losing position (invalid setpoints)

      We need 100% stable indoor flights ASAP.

        Hi, can you please review the VIO troubleshooting guide and see if you can capture the proper debugging data?

          Any word on the "RC Loss" problem?

          I am continuously experiencing the "RC Loss" problem, even from a few inches or feet.
          This has happened so many times, even during the flight the connection to the RC is lost and done is on it's own and it land (fail safe).

          As you can see in the below pictures, the drone is connected with the laptop over WiFi, RC is ON and has enough power (3.9 V).
          Camera preview is available on the laptop, and QGC shows a "Manual Control Lost" message on the screen.
          I don't see the signals bar on the screen of the RC.

            @muhammadbilal1 those RC operate at 915MHz. Any chance you have interference in the area? Alternatively, maybe the wiring between the receiver and the VOXL 2 was manipulated or came loose?

              @Moderator As far as I can see, there is no interference in the area, I am working along for like 100's of meters. I don't have any such equipment in my premises which can interfere.

              Physically, I checked the "915MHz ELRS Receiver" (BetaFPV Nano RX) and it's not lose. What else I can check?

              Please help us fix all the issues, we are in agony since we started using this (Starling) kit.

              I have other open issues too.
