    Compass Calibration, A Complete Primer

    How it is in case of really big drones or, for that matter, airplanes? One has to do the same dance to satisfy the compass?

    P3 Standard - Initial Impression

    The video is sort of jelly. Is this normal for that camera/P3S?

    I am looking for a review of Phantom’s cameras

    I am not coming from DSLR. I'm too older than that :). I still use "old fashioned" film cameras -- 4x5, 6x9, 35 mm, polaroids, as well as all kind of digital stuff. I always try to adapt my style and expectations to a camera. I am sure both Phantom's cameras can be used to their advantages and...

    I am looking for a review of Phantom’s cameras

    I don't expect these cameras would be perfect, but I'd like to know their weak spots in advance. Fringing or lens distortion one can easily repair (and yes, your material shows distinctive lens distortion). As a graphic artist and photographer I am mainly interested in stills, but I use videos...

    I am looking for a review of Phantom’s cameras

    I've thought so. Seems nobody cared to test the camera properly. This is what I've gathered so far: 1. Quite annoying fringing; 2. Noticeable video compression in the 4k camera (stronger than in 2.7k); 3. Poor handling of low contrast scenes; 4. Noise in shadows and in low light conditions. 5...

    Compass Calibration, A Complete Primer

    Once set is set. Gyros would keep the orientation in space. A check every second or even a couple of seconds would be enough.

    Wind shoold not be a factor. Two or one giros and GPS would do the trick.

    Compass Calibration, A Complete Primer

    Sure, I know that. But this method would be simpler than relying on the magnetic field. A drone would calibrate "the compass" by itself. What's more, while flying a drone would be able to adjust "the compass" constantly. Another thing: A simple solution to fly-aways caused by erroneus GPS...

    I am looking for a review of Phantom’s cameras

    I am looking for a comprehensive review of Phantom’s cameras. All Phantom 3 models are basically flying cameras, but one could hardly tell this by reading posts and reviews. Before buying P3A or P4k I would like to learn more about theirs cameras: sharpness across the picture, vignette, dynamic...

    Compass Calibration, A Complete Primer

    I don't understand why Phantom uses such an unreliable device as a compass. GPS and a gyro should be enough to define and maintain orientation in space.

    IMPORTANT: DJI Go app 2.50/2.51 enables GEO functionality

    I don't think the DJI NFZ are about drone pilotes' recklessness and accidents. It is about terrorism. DJI is scared a drone of theirs would be used in a terrorist attack. Imagine what would happen...

    PS3 4k vs its bigger brothers in practice

    I am just about to buy PS3. The most important feature for me is a camera. I need a 4k camera on my drone. The new PS3 4k seems to fit the bill. I know the differences between PS3 models listed on the DJI site, but how is it in the real world? Yesterday I found an info that Drone-World had...
