I have had my Phantom 3 for two weeks. Yesterday when I launched it, it behaved as if I were holding the left stick in the down position at all times. It would still climb and fly, but it fought me the whole time (just trying to go back down). It is difficult to describe. When it's supposed to hover, it just goes down at full throttle, and always seems to be "trying" to descend. I calibrated joystick, switched modes. Drove 5 miles away and relaunched. Same thing. If I get it worked out I will update the forum. Thanks

The sticks have springs on them and they should spring to the center position. This is where your Phantom should be hovering in the air and not moving. Is there any errors on the DJI GO App? What are the two back lights on the Phantom doing? Are they flashing green? If everything checks out, I would calibrate the sticks through the settings in DJI GO App and see if that checks things.

Thanks. I did calibrate the sticks. It's a difficult problem to describe, really. It doesn't seem as if it's the stick itself

So what are those two back LED lights doing while you are flying. If there is a problem, it will flash the lights in a color code which you can check the manual (or the link below) what that light pattern means.

Check your battery condition. Cell, percentage etc. Could be battery loosing its power.

I am an idiot. My friend had just flown my drone and knocked off about an inch and a half of a blade. I didn't even notice. Even dumber is that I had seen him clip the corner of my house, but he didn't report any irregularities and flew it for a few more minutes. I had completely forgotten about that by the time I flew it 2 days later, and didn't notice the broken rotor. Flew the heck out of it tonight. I'm still a noob and get nervous whenever it gets out of sight but man is it awesome

Good to hear you were able to find the problem, thanks for the update. Happy flying!

Lesson #1: Always do thorough checks of the craft before take-off.
Lesson #2: Never let other people fly it

You might want to introduce a pre and post flight routine into how you treat your $400 quad, before the horse leaves the stable!

Sounds like prop guards would have saved the day.
