Hi all,

Was just about to order a P3P but I've noticed a few videos recently with an unlevel horizon. If I understand correctly, this is due to a defective gimbal or IMU. Just wanted to know how many people have had this issues, and if you have, what can you do to rectify the problem? Is it the result of a miscalibrated IMU or is it something more serious? I realize this could be rectified in post but I'd rather not have to chop off some of the video

Many thanks

Oli

The IMU needs a calibration followed by a gimbal calibration.

So it is a user-rectifiable problem and does not need shipping back to DJI?

Yes, it can be fixed from the mobile app.

I believe you can also tweak the gimbal orientation manually if required.

l had issues with my gimbal and camera out of the box, but gimbal tilt is not one of them. Mine is straight. Maybe we could do a poll to see how prevalent it is.

It seems to be an issue that comes and goes. It might take off with a level horizon, spin it 90 degrees and it might tilt a bit. Fly around, and it might go away. It is annoying and DJI should be aware of it. It is almost certainly not a hardware fault (that will be corrected in the Phantom 3 anyway). If it can be fixed, it will likely and hopefully be fixed with firmware update.

Doing the full IMU calibration and also calibrating the gimbal does lessen the problem significantly. The Phantom 2 Vision+ would also sometimes do it. Except it was less visible because of the wonderful 720p video link to your iPad with the Lightbridge system and because the Phantom 3 uses a rectilinear lens (which is awesome) rather than the fisheye lens of the Phantom 2 Vision+ or GoPros.

It is an issue and a nuisance and hopefully DJI can improve upon it with a firmware update. It shouldn't hold you back though - as there likely will not be anything better in this generation of the quadcopters - and any possible fix will almost certainly be via Firmware-update.

I've done some correcting of a slightly tilted horizon in my photos and videos. It does not lose very much. Especially if you get the Phantom 3 Professional and do videos in 4K there is a lot of pixels to retain the quality of the image to a degree as I will say it is virtually not visually detectable that the video was rotated a 1 or 2 degrees.

If you decide to get one of these great machines (I have a Phantom 3 Pro (flown 38 flights so far - and hundreds of flights on my P2V+)) and you would like to buy from DJI directly (think they might have the quickest delivery time currently over Amazon etc.) I sure wouldn't mind if you'd use my DJI-publisher-link to buy it   That would give me an 8% credit to buy accessories etc. from DJI
