Was at the same location the day before and flew perfect, next day same location took off and within 5 seconds got a Compass Calibration Error, the P3 is basically impossible to control if this happens, seems like no matter what I did could not get it to go in the right direction, well I hit a tree and landed on asphalt, some how the P3 survived the crash with nothing but broken props. After the crash I realized I should have probably gained altitude until I could figure out how to control it.
