I was flying yesterday at 200 ft when my phantom went into RTH all by it self. I had 3/4 battery still left. I lost all control for 6 seconds then regained control and landed the phantom with the remote. When it got to the ground it was blinking a slow yellow but I had the remote controling it which hasnt happened before. I went home put a fresh battery in it and got blinking green at start up, but if i pick it up with the propellers off and tilt it to the side with the remote right beside it . I get the slow blinking lights gain. Now I am afraid of a fly away. Any help out there.
