    Strange issues with navigation system

    Just as an update, everything is fixed. Used the new chip, calibrated imu then compass then vision sensors and no more issues. Replaced a wobbly back leg while I was at it but I did clean all the connections with compressed air and alcohol and made sure everything was plugged in firmly. She...

    Strange issues with navigation system

    So I swapped back to the old board and still not getting a GPS signal. Everything looks normal under the bottom cover. Not exactly rocket science. Thinking about replacing the GPS unit. Very frustrating situation since the crash. Glad it's not my only bird.

    Strange issues with navigation system

    OK if you haven't read any of my posts yet. I had a minor accident a couple months ago. Camera unit was completely replaced by drone nerds because they didn't know how to change the ribbon cable /video transmission cable. So I ended up getting a second mavic on ebay for $250 that had a missing...

Still got the red light so I removed the SD card, formatted it on the pc, downgraded to factory defaults and then reinstalled the newest firmware and it seems...

    Ultrasonic sensor failure after firmware upgrade

    I'm getting this error also after repair and firmware update.... Maybe issue with ios devices doing firmware updates and I've been doing updates on Android? I only get the error when I get about about 20 ft or so. Did a roof inspection today and didn't get the error at all but still experiencing...

    Ultrasonic sensor error land immediately

    Still getting the error but only after getting over about 20ft. Anything under that it's fine... I did a roof inspection today and before the sensor error I was having drifting problems and after I went above 20ft or so and got the error I didn't have any drifting issues

    Anyone? Just had a camera replaced at drone nerds.... They replaced the whole unit even though it was just a ribbon cable and video feed
