Hey all, total newbie here. (I know groan) Just bought my first Phantom. Got it in November, sent it back because the propellers would not turn. Finally got it back from repair and still having issues. Ive followed every single step. Have calibrated dozens of times. Lights blinking green should be ready to go right? Anytime i try to accelerate and fly, it either one, immediately tips over or will fly uncontrollably with a horrible wobble. almost seems like it loses contact with the controller. Ive connected with assistant and everything seems to check out. any ideas?
