****Note*** the second set of flashing after the green flashing is "RED" It looks a little yellow in the video but the three flashes are red. See YouTube video: http://www.youtube.com/watch?v=4N7beLEs1aQ&feature=youtu.be Since I first purchased my Phantom I have had a lot of problems with drift and such. When I first purchase I could not connect to the assistant and had to purchase a new LED unit as the original was faulty right out of the box. Can someone help figure this problem out that I am having currently please. I tend to have drift issues still with this unit. As you can see my mod value is quite low ( 170 ) as I understand MOD value Ideally should be around 1500-1800 according to the compass calibration video from DJI. I do not get the long "Red" "Yellow" flashes that would indicate a compass error. I am curently in Mexico on the fifth floor of a condominium and when I power up the phantom I get the flashing that you see in the video. I get 2 x fast green, green, then Red, Red, Red. If I am outside and do my compass calibration I get the same thing if I am in GPS mode. If in ATI mode the green 2x flash is replaced by a quick two yellow flash. I am actually able to fly it not to bad although there seems to be drift issues. Again as you can see once i hook up to Assistant software my MOD value is very low. I have tried in the past to use a magnet to bring up the value but without any luck. Any tips as to what I might try next or as to what the LED indicators are telling me? and why the IMU assistant does not see a reason to re-calibrate with such a low MOD value?
