Hi, I have been experiencing problems with my Phantom 2. It was working perfectly and had no problems for the first month. 1) When flying it drifts quite badly in GPS mode when no movement is being asked of it - I assume this is a compass problem, I have recalibrated it. 2)It will not power down correctly using the CSC I used to start it with (Which I have been using with no issue up until now) It topples over when trying to power down using CSC, there is no issue with it powering down just using the down control. After the first 2 times this happened I started it up again and noticed that when I go to initiate the CSC the motors start moving faster like it is being asked to fly somewhere. I'm guessing this is why it topples over. When I couldn't power down using CSC without it toppling over I switched off the controller in the hope that would make it power down (which I now realise wouldn't work), it erratically flew away and I couldn't regain control of it. It flew up in the air and for no apparent reason moved away from me and then started lowering itself into some trees where it got stuck until a big gust of wind dislodged it. NOw I have lost confidence and I'm worried I'll lose it. It was in ready to fly non gps mode. I still can't see why this would make it fly away when I powered down the RC. I have now updated the firmware on both phantom 2 and RC. Recalibrated the compass and the RC but the problem still persists. I am too worried to fly it just in case it has a wobbly again and decides to crash into a tree or something more solid. If anyone has any ideas please could you help. Thank you.
