have about 130 flights and never had an issue. Then yesterday happened. I was in the Smokey Mountains and wanted to get a few pics before I left. I updated to all of the latest firmwares and app updates last week. I went through all of the compass calibrations and did not have any issues during warm up. Once I got the green light I took off and let it hover for a few seconds to make sure everything was working properly. About 3 minutes into the flight, I lost signal and it started drifting away fast. I hit the RTH and eventually everything ended good for me. I uploaded everything to healthy drones to see if I could get an idea about what went wrong but I am not too familiar with what exactly I'd be looking for. Can anyone help me out with this? Thanks in advance! I don't want to put anyone or anything at risk flying until I know what went wrong!
