I upgraded the firmware and tested,, seems to work fine for a few minutes.  I flew it again thinking it is fine, as soon as it took off, I had compass error and kept flying higher and away from me.  I lost the drone and was unable to recover it to find out what happened.

Sorry for your loss, florod63. I'd suggest you to sync your flight record and then get in touch with our US tech support. Here is the contact information:
