So, I'm from eastern Europe, but after recent changes in US government, I'm thinking it'd be worth it to get to know how to fly drones that can be useful on a warfront.

Yeah, I'm terrified. For me, it's a real possibility that Ukraine will fall and I'll have to pick up the slack. In the olden days I'd start learning how to shoot a rifle, but nowadays I think learning how to pilot a drone makes more sense.

What do you think is the best drone to buy to learn how to control those, in a war context. I just want to at least learn a bit how to control those and have a bit of experience if it's necessary going forward in the next few years.

Second question: Do you have any guides that you would recommend on how to print and build you own FPV drone? I know a bit about electronics, worked a bit with Arduino, Raspberry and different microcontrollers, but I'm not sure where to start when it comes to drones. Which controllers to buy, which rotors and motors to buy. I'd love to be able to either be able to print my own replacement parts or build a drone myself, so if you have any nice guides on how to start with that, I'd appreciate it. Thanks!
