Went flying today in absolutely magical late afternoon lighting. The bird flew flawlessly but something was wrong with video recording—it would switch off after 6 to 8 secs. When I checked the card later, all the files were either 1 or 2 secs. Came home, reformatted the card and RE-downloaded/uploaded the latest firmware. Managed to run video—on the table without arming the motors—for 50 secs without it stopping. Re-charged the batts and will test again tomorrow.
