    It’s a DJI Phantom, made entirely of plastic - the battery has about 50% of the weight of the drone, the weight should add to about 1400g, the motors are probably 2312 with 900-ish Kv (it’s like the HP of a car), stock propellers are about 10 inch in diameter - that would give it roughly 2.5 times more power than weight, so a maximum lift off weight of about 4000g (a little less than 4 lbs). Maximum speed is, according to the internet, 45 mph.

    For clearance: my self-built drone with a carbon fiber frame has 1200 grams (with battery), motors are 2207 with 1980Kv and propellers are 5 inch - a quarter of the size. I calculated about 12 times power to weight, making it able to lift off with up to 12 kg or 20 pounds. I think the maximum speed should be around 80 mph.

    Yeah, the eagle probably destroyed it without getting hurt.

      What resources are reputable to look into custom drone building? That sounds like a cool hobby for my teenage sons and I

        Definitely Joshua Bardwell on YouTube! He even has a website https://www.fpvknowitall.com/ where he even has blueprints of builds and a lot of info! Reddit r/diydrones is very helpful, as well r/tinywhoops (small drones) and r/fpv (I posted my soldering there and was corrected multiple times.

        I’m deep into FPV where you fly with goggles, so I’m no expert in programming, but I’ve seen quite some posts about fully automated drones there!

      send your blueprints to Ukraine and watch your intellectual newborn become the bane of the autocratic world

        Weeeellll originally no, but I figured that showing a little more knowledge on this topic would make me sound a little more competent.
