It’s trivial to build your own with some basic soldering skills. I’m curious to see how this shakes down over the coming decades.

I built some non-compliant (also non-autonomous) 450g drones before the 250g weight limit. They’re only for acrobatics at treetop level or below. It’s kind of silly IMO that this style is required to have a transponder now. This is speaking as someone who flies planes.

For the store bought ones that require no forethought - I am glad those are regulated.
