    Hello modal AI,
    I have similar issues with all my starling 2 drones, and I keep crashing them. When I toggle my controller from manual mode to position mode, I expect the drone to hold its current height, and hover there, sometimes it does that, sometimes it lands (and I am sure it's not because of the battery because I have done this with fully charged batteries), if this was only what happens, I wouldn't really have much concerns, but sometimes, when I toggle the switch, the drone flies away and I can't control it with the left stick except I use the kill switch button, the drone eventually crashes. I would have sent a footage for better visualization, but I don't have the privilege to upload videos.
    I have been working with these drones for a little while , but I can seem to understand why it does that.

    This is the third drone I am sending in for RMA, and I don't know why they are crashing. I can't keep crashing drones.

    Kindly help me please.

    NOTE: My drones are using different SDK versions (1.4.5, 1.5.0, 1.6.2)
    I have used qvio, i switched to open vins also.

    Also, sometimes on QGC, i get position and height estimate unstable, I hve calibrated the compass, gyro and accelerometer several times, yet i still have same issue. There are times where I get strong magnetic interference error also (i try to move the drone far away before powering on), I have attached the image of my lab, to see if this is the major cause. Right now, I don,t know why it behaves like that. I also attached my controller to see the toggling switch toggling i meant.

    Also, what do I do when i get position, height and velocity estimate error ?

      @taiwohazeez start with going through the troubleshooting tips: https://docs.modalai.com/flying-with-vio/#troubleshooting-vio

      qvio_overlay or ovins_overlay are going to be very informative
