I literally did everything by the book and calibrated the compass before flight. I started takeoff in and empty parking lot (coordinates in google are 42.879312, -78.883090) and for some reason i get massive interference after take of and hover at like 10 ft and then it switched in atti mode. I skimmed the ground before it drifted then eventually rolling. At this point i turned the motor off and tried again this time using the box has a platform. Same thing happened. Im too afraid to even get out of beginner mode because I don't want it to go anywhere remotely out of sight. My question is, and it may be stupid, but does some asphalt have a metal or reflective compound in it that could be causing issues?
