A really complex aspect of building a copter for newcomers is what to buy and how. ZiptieAI focuses on buying in the USA (,, etc). In Ukraine it would be AliExpress.


Amazon is (of course) the best for buy many things. What really makes it useful

  • Search engine

  • Purchase history (this is something you will refer back to quite often while building a drone)

You can get many components (such as flight controller / ESC stacks) from this US-based supplier.

Aliexpress (and other Chinese suppliers)

I have never ordered from Chinese suppliers because of my concerns about payment info security. I have also heard that you can get good deals on Aliexpress, but you have to be careful about what you buy.
