Build your own drone (pt 7) – Reflection


Why in the heck would you build a drone?

It’s incredibly fun to build your own drone, but you won’t be able to get it to fly right away. If you’re planning on squeezing in some airtime the same weekend you buy it, you’re better off getting a ready-made one.
But here is my 2 cents: the pleasure of seeing the drone you build with your own 2 hands, flying up in the air, is priceless.

It’s fantastic that you get to choose all the components yourself. Want heavier motors? No problem, just install them! Broke an arm off your frame? Don’t sweat it, get spare parts.

So what did building my own drone cost me?

You mean except from the pounds of chocolate I had to buy to bribe my girlfriend into spending the weekend with me, testflying the drone?

Not too much, in my opinion. Below you’ll find a list in which I tried to sum up all the things I used. Of course it doesn’t contain everything: materials, delivery fees, wrongly orderded pieces, … have all been excluded from the list.

Keep in mind that this is just a start. I’ve been working on my drone and adding/changing parts on the go. (e.g. I installed a new Flight Controller.)

Anyway, about that list:
