It seems our Phantom has a new sequence of flashing lights. When powering on now we only get the yellow flashes showing IMU warm up. The switch is in GPS mode no green lights or red for satellite. After a couple minutes the yellow goes away and then I get the green light and the red lights showing the satellite status. It used to show in this order green, yellow, red when powering up. Is this a newer type of flashing or is there something faulty? Once we have just the green flashing light take off and flies perfect. I am just wondering why the lights have changed. it has done it this way or the last few flights. All have been un eventful. We have been using RTH as well with great success. Probably worrying to much. If I can figure out how to post a video I will. Thanks. Chuck
