    During a descent, i rotated the drone 360. Suddenly it started to wobble, it did not react to a ascent, and the following crash was inevitable.

    The Camera took a blow. Now. When i power on the drone, the gimbal goes haywire. Rotates frenetically in every axis and seems to be suicidal. Dji suggested a firmware update might do the trick. I had my doubts but did it nonetheless. Ofc. it had as much effect as a prayer would have.

    Now. The camera works fine but the gimbal seems to be sick. Are there any tricks or should i just order a new one.. ?

    In advance, thanks for all help.

    *desperate*

    Have you tried to calibrate the radio?

    Try an advance IMU calibration, otherwise=screwed.

    You can get of that "inevitable" crash... simply move the right control stick in any direction... this will take you out of your rotor wash and prevent a crash. Adding power just makes it worse. You encountered a "vortex ring state". Deadly to rotorcraft.

    Thanks DrJoe, i`ll try that next time. I got me a smaller drone to practice with. And I have been able to recreate the scenario, excluding "bugs" and finding that the error is indeed me. With some practice on this cheaper variant, I will hopefully make the correct maneuver into a reflection.

    Never got so far as to try an advancde IMU calibration. Bought a new gimbal and replaced it today. Works as it should, only to pair it up with the range extender. But I will switch back one day and see if an advanced IMU calibration can transform the damaged gimbal into spare parts.

    Yes. Tried a forced firmware update as well.

    Not saying this method won't work, but if in Naza mode, just be cautious to not hit any of the 4 possible CSC combinations when trying different things with the sticks to get out of vortex ring state
