    drone footage of the 2024 eclipse

    I used my P4P to obtain some drone footage of the 2024 eclipse. I aimed the camera not at the Sun but rather in the direction of the approaching shadow. I left the drone hovering above while using a Nikon Z6ii with a 560 mm lens to get some photos of the corona and prominences.

    DJI GO and Litchi offload from iPad -- very annoying

    Yes, that is what I meant -- it offloads apps that aren't used regularly. Thanks for all of your inputs!

    DJI GO and Litchi offload from iPad -- very annoying

    I only recently found out about this feature. The problem arises only if you don't use your iPad for a while. It can be hard to figure out the cause of such sporadic behavior. Someone on the Mavic forum claimed that this feature is turned off by default, but it sounds like you had the same...

    using a P4 to drop a line in place

    One of my family members is an avid fisherman. I'm going to try this idea with him. Can you please suggest how to attach the line to the drone? I have an idea in mind where it's loosely attached so it can be released with a slight tug on the line. However, I'm a firm believer in learning from...

    using a P4 to drop a line in place

    For your application, I don't believe there would be a need for the arm that extends off to the side. It is required for putting a line in place, however, because the drone must come down below the line after putting the line in place. The pendulum effect is more problematic when using an arm. I...

    DJI GO and Litchi offload from iPad -- very annoying

    I have occasionally had an annoying problem and finally realized what was going on and how to avoid it. The iPad has a "feature" in which apps that aren't used for a while will automatically offload. More than once, I have been out in the field ready to make a flight and then suddenly realized...

    using a P4 to drop a line in place

    I experimented with using a P4 to get a line in place. For climbing trees, a bow and arrow rigged with a fishing line is often used. That approach is effective, but in some cases it's necessary to thread the needle with a near perfect shot. I once made such a shot that placed the arrow just over...

    Regulations for maximum altitude in areas with sloping terrain?

    Thanks for the information. That makes sense, but I was confused about this for a couple of reasons. Most of my flights were done in an area with flat terrain. So this was never an issue for me. I always assumed that the altitude that shows on the controller is the maximum altitude by regulation...

    Regulations for maximum altitude in areas with sloping terrain?

    It is my understanding that, according to regulations, the maximum altitude is 120 m above the launch point. But how is this applied in an area with sloping terrain? Suppose that two pilots are located a few hundred meters from each other horizontally, with Pilot A 100 m higher than Pilot B. If...

    When you lose controller signal and GPS at the same time?

    A smart way to design a drone would be for the drone to gain altitude in the event that GPS and signal are both lost. This would give it a chance to regain one or both, much better in my opinion than to simply land!

    Using two drones at once?

    I was wondering if any of you have ever used two drones at once? This may sound risky, but there are various scenarios in which the drones would need attention only for parts of flights. For example, fly one drone into place and leave it hovering (e.g., to film an event), and then fly the other...

    combining drone footage with audio from below

    Thanks! As shown in this photo, I deployed the audio recorder with two external batteries so that it can record continuously for a week. There were some intensive rain storms, but everything stayed dry with the microphones protruding through a hole in the bottom of the case. The furry covers...

    combining drone footage with audio from below

    I recently started combining drone footage with audio that is recorded below (during the same approximate times but not during the drone flights). For each of the following examples, I used a P4P to obtain the video and a Sony PCM-D100 to obtain the audio: jungle in Peru swamp forest in Louisiana

    Who will be the last P4P pilot?

    I just edited my profile so that my age shows. I'm 65 but still going strong!

    Is V2.0 compatible with V1.0 controller

    Thanks for the replies. I linked it to the controller, which confirms that it's a V1. During the phone call, they told me that there must have been an error applying the wrong sticker (which says V2.0) inside the battery compartment.
