I downgraded my firmware yesterday from 3.04 back to 1.08. I did a test flight and was checking my Flytrex data afterward and it said I unlocked the "Diver 50" badge which says I descended 50ft below my starting point. Which I totally did not. If I did, Id've been underground. I can't think of anything that may have caused this except that the elevation info on google maps is wrong. Here's a link to the Flytrex data: http://www.flytrex.com/mission/marc-m-47488/ The flight went pretty well but this has me worried that my bird may not know where it is when it's in gps mode. It was very windy yesterday and I flew after a pretty crazy rain/hail storm. When I look at the flight pattern, it looks pretty accurate. You can see how long I was messing around very close to takeoff for the first 1/4 of the flight. If you slide along the bottom, you can see the elevation I started from and where it "thinks" I descended over 50ft. The distance from takeoff is like 2 ft away. Anyone have any ideas of what happened here?
