    Detecting animals

    I just did a quick Google search on the subject, and you can find dozens of really good posts about the technology and methods used to spot animals from drones. You'll probably have better luck with that than in this forum.

    Any gain to upgrading to iPad mini 5?

    I don't think you'll see any difference whatsoever except for the brightness, and even that won't be much. I own and use a iPad Mini Gen 5 for my drone. Two days ago I resurrected a friend's iPad Mini Gen 2 which he was using for flying his Mavic Air. Once I had it running again I used it with...

    iPad ?

    I've never owned a cell phone, so when I bought my iPad mini (gen 5) last spring, I spent the extra $$ and got one with the generic SIM. I already had a VOIP number I use as an extra line on my home PBX and was able to find an app that lets me use that on the iPad. I then found that, because it...

    Max Requirements for 4K 30fps video

    If you are asking about how to play the video, rather than how to edit, the video, they key to smooth playback, on any speed computer, is to use the right software. There is a massive difference in the playback smoothness of MP4 4K video depending on the playback software. On the PC, VLC...

    Poll - what resolution to your upload to YouTube as ?

    I'm not sure what you are suggesting that the OP do. Can you control the bitrate? AFAIK, you cannot. Therefore, if the bitrate is low, then that would argue for using lower resolutions since, at a fixed bitrate, you'll have fewer motion-induced artifacts if there are fewer pixels. Is that what...

    Poll - what resolution to your upload to YouTube as ?

    Upload all the versions you listed, and then look at the results and see if you can tell a difference. No need to do a poll. Since most videos are viewed on small screens these days, 720p is more than sufficient. And, if you know what you're doing, 720p looks just fine on a 55" screen (it's...

    Unable to import Mavic 2 Pro file into Vegas Pro 13

    First of all, uninstall the K-lite codec pack. It can mess up your system. I've used Vegas for over fifteen years and had almost 7,000 posts on the old Sony Vegas forum. Generally speaking, Vegas is great at playing just about anything, but your version 13 (which is the one I use) is old enough...

    Question regarding use of photos

    So, are you a lawyer? If not, by your own definition, why should anyone read and believe what you say? You clearly state that wrong information was given, but then go on to state that the right information was also given, but you don't indicate which was right and which was wrong. I'm not a...

    Question regarding use of photos

    Another thread ruined by the "drone police." Why do they think it is their responsibility to play policeman? I am getting VERY tired of having people rain on everyone's parade rather than trying to help. Is this what people here want??

    Two More Battery Failures

    Thanks for that. I didn't see that, but I'll admit that I read through the four pages of posts pretty quickly. If that is true, then that would be the entire explanation and, if you don't have a battery manufactured within that timeframe (which is getting to be quite a long time ago), you don't...

    Two More Battery Failures

    I just skimmed all the posts, and while there are lots of anecdotes, I don't see much in the way of definitive information on underlying causes. Since not everyone has experienced this, that seems to rule out an underlying design defect. Also, LiON batteries are used in thousands of...

    iPad ?

    Intriguing idea. I never thought of doing that. I just looked at my controller, and I wonder why you chose to cut into the body rather than just trimming off the end of each plastic controller arm? That would seem to be less destructive. Another approach would be to replace the two metal...

    How many batteries are to many?

    I just now did this test. To go from 40% to 100% took one hour and three minutes (1:03). This is on my Mavic 2 Pro with a battery that has logged about ten flights, so relatively new.

    How many batteries are to many?

    That's a really good question. I forgot about that. I have a little muffin fan that I modified to use as a cooling fan. It can easily run off the little 140 watt inverter I have for my car. I point it at the battery after I take it out of the bird and I cool it down for about 5-10 minutes...

    How many batteries are to many?

    As an engineer, I always do calculations. Based on those calculations, I see no need for more than three, assuming you have a way to charge the batteries. This is how I arrived at that conclusion. 1. For my Mavice 2 Pro it takes 90 minutes to charge a "fully discharged" (20%) battery. In my...
