I've noticed a few times recently when I've had my phantom hovering in front of me, say 100 feet up that when I push the stick to move it forwards,  it actually fly's 45 degrees to the side instead.  It's almost as if it's in ATTI mode and being affected by the wind, but it's not, it's in GPS. It seems to only happen when I go forwards. Any ideas, it's starting to make me nervous to fly?!
The transmitter is at the 'p' position by the way.

As far as I know the only way to turn IOC on is to flip the transmitter switch to 'f' but I haven't, I've got it at 'p'.

What makes it even more weird is that this only happens sometimes,  it's not every time I push forwards.

I'll try a compass calibration again but would be interested to hear if this has happened to anybody else?

Have you calibrated the IMU on a known flat surface? Rest all settings first and then do it. It doesn't list it in the instructions but I had an issue with uneven power on left and right movements of right stick which I didn't notice because the GPS is so badass. In the P2 they would apparently drift if they weren't calibrated right and it would be noticeable, but it's not on these.It might make a difference. Either that or one of the other calibrations in the menus, like RC Calibration in the 2nd tab down. You can only do it when the P3 isn't connected, but that's where the stick inputs are defined.

I've never seen my P3A do that in "P" mode.  I really can't even guess what could cause this.

Beware. There has been 3 reported cases of the P3's hovering and then going haywire and coming crashing to the ground and I'm one of them. I was flying yesterday and was staring my approach back home when all of sudden the drones starts rocking back and forth side to side and crash landed the next block over. You can check out the thread on PhantomPilots.com and look up Phantom 3 malfunction and crash. Myself and two other pilots had the drone do the same exact incident happen to them and we all recorded our flight data from DJI's app to prove what our drones did, all videos look very similar. As all were at hover , over 100' in the air when all of sudden they go into a death spiral. Just wanted to give you a heads up on what happened to me and two others and I have a feeling we are not the only people it's happens to. So if this is an issue that more people will use DJI's app and flight data to prove there is a problem

My P3P did this to me after I switched to a ipad mini 4 with cellular/wifi, never did it for over 85 flights on my Android device. If I sent it forward it went 45 degrees left, and backwards 45 degrees right, very weid behavior, I was in "P" Mode and had all satelittes (14) I switched it to atti mode the back to P mode and it finally flew correctly, has be boggled!, yes I did do calibration and imu.

HI, have same problem,
when hovering near me and i give stick command  " backwards" the phantom goes "to the right"  i dont panic let him hover and few seconds later its normal like it never happend. (p-mode)
as FILMWORKS says  its like it is in atti mode ad drifts with the wind, only its NOT in atti bud in p-mode.
everything ic calibrated and checked...


also notice 2 time wen hovering 50 meter away and the give stick command "forward" it wants to go fast back for 1 second befor going forward (making fast back forward movement, kind of sceary to see like it wants to make a flip ;-)
till now al went ok, my advice dont panic ;-) let stick lose , let it hover try, to slowly take control, wait until its normal.

got a little scare flying it.

hope it wil go away in next update

ps: sorry for bad englisch ;-)
