altitude showing -30 feet on the ground

[stang10189]

altitude showing -30 feet on the ground. I have updated all firmware, preformed a advanced IMU calibration and then calibrated the compass. This was my first flight. Any suggestions on how to fix this? I am worried about RTH when it thinks its at -30ft when on the ground. Worried it wont goto the hight I set in the app and end up hitting something durring RTH. Thanks in advance.

don't understand why I'm not getting a loaded that someone posted to this thread. I will try deleting the app and reinstalling it and also read that post you put a link to. Thank you very much

Hadn't thought of that and very well might fix it !

Perhaps a stupid question (I have a lot of them!) but wouldn't GPS be more likely than compass problems?
