Hello all, I purchased the Phantom 1 (version 1.1.1) from a coworker that was brand new. After doing countless hours/days of research and learning from him(an experienced phantom pilot for 8 months) I was ready to fly myself. After learning, researching, and flying this phantom weekly(if not daily) for 3 months I am extremely happy except for a couple flights. The first major issue I had- I was out hunting in arkansas and did not calibrate the compass before flying it away from my normal flight grounds in Georgia. It was late at night, I was flying very high when the phantom started to drift off into the distance away from me. I lost all control. It looked like the phatom was only pitching and not elevating/descending. The first thing I did was take off GPS mode to ATTI mode and was unable to regain control. Then I switched transponder off hoping it would return home. Nothing. After a good 60-90 seconds of watching nothing happen, I was very nervous. The phantom just kept drifting further and further away. I must remind everyone- I had great GPS signal before take off, all rapid flashing green lights, waited anther minute before taking off with slow blinking green lights. The home point was set. Well, FAILSAFE did not do its job here. I am guessing the phantom got out of range with transponder. I have no idea why FAILSAFE did not work. I know if it did not have great GPS sateelites then it should have hovered and landed straight down, if not return to home position. My next move was jump on a 4 wheeler and race towards the phantom. I tracked it down and in the distance I saw it coming in for an auto landing. Still was unable to get control via transponder, but I did recover the phantom. Thank God. Well this worried me and I read into all the flyaways and did lots of research in hearing similar stories... I have been flying the phantom for a couple more months when it did the same thing last night. This time in the city of Atlanta, with no 4 wheeler and open fields to track it down. As soon as I realized it was flying away, I switched to ATTI mode and phantom was unresponsive. Turned transponder off and still nothing. I got in my car to drive closer and after a couple minutes turned back on transponder which I was able to regain control. Flashing red light, low battery warning and it was VERY far away. Flew it home and landed safely before the battery died. Can anyone weigh in for help? I believe its the calibration issue or maybe cell towers? I was clear of powerlines so that cant be the issue. Not sure?
