I just got back from a trip from Tahoe to do some footage work. Got home and had to do the update on the drone and when I took off I noticed that it only went up and down and sometimes it would bank left or right but not all the time, the bird would fly backwards but not move forward. Like we always do... I PANICKED! I did the Firmware Refresh - Did the Controller Firmware Refresh - did all the long process and not thinking the very obvious. It was just the OBJECT AVOIDANCE SENSORS kicking in - no wonder it didn't want to move forward nor bank to the left or right since I there were objects within the range of the sensors. For a minute I was thinking I had a bad bird - thankfully the sensor does work. So next time - I tell myself before I panic is to check the settings and obvious. LOL to myself.
