Hey guys. Well... I've had my Phantom for a few weeks now and have absolutely loved it... zero problems at all. Last night I updated my firmware to 2.18 and NAZA version 4.0. Well, today I took the Phantom out and was showing a friend in a parking lot how easily it flies and it got up just fine but began to drift away from me and didn't seem to respond to my controls. I had it in GPS mode and switched into Attitude but it didn't help. I turned off the remote hoping it would fly home but it never did. It was seriously the most gut wrenching feeling I searched for an hour or so but it really could've gone anywhere so I left and am now hoping someone finds it and calls me since my number is on it. I have a few questions that hopefully someone can help me with... 1. Why can't you track the Phantom's last known position from a computer since it has a GPS built in? 2. What is DJI's stance on flyways? I don't think I should have to pay (at least full price) for a new one if the Phantom flew away uncontrollably after a software update. 3. If I do have o buy a new one where can I get a Phantom only for a reasonable price ? I emailed and explained everything to DJI but haven't heard back yet... Thanks in advance for any help.
