If you are sure you want to fly but not sure for how long, and on a budget, then Bartek is right, but if you plan to stay in that hobby for longer, then invest, so you will only pay once ;)

(a post on EU/EASA rules)


One of our local pilots, who was flying after sunset, was admonished by police during the control for not having navigational lights 😵 and warned that this may be a subject to a serious consequences next time, as this can be treated as causing threat to air traffic safety 🙃 I forgot to mention that he was flying a microdrone (1.8'').


I checked it, and apparently in EU there is an active rule 2019/94 UAS.OPEN.060 / point 2G: the operator ensures that, during night operations, a flashing green light is activated on the unmanned aircraft.


The law does not state any technical details; the light must be green and flashing. So the next thing I did is build a lightest led light 😎🐝 I bought a 3mm led light with an inbuilt flashing chip and the 150R 0,6W resistor. Both super tiny. Together with the AWG30 cables and thermal coating it is 0.38 g. Works, drains 20mA, so it has not much impact at all on the current, and I succesfully added it to my 1.8 and 2 inch drones.

Thermovision cameras: I have been thinking on buildling a drone for night flying with switchable cameras - one with Ratel Pro (as it is excellent for this purpose) and second - the 256x192 4MM CVBS for environment without much light. Anyone tried this model? 🫠


I wonder how usable it is eg. to land in total darkness in zero-light enviornment. I was flying yesterday after 11pm with Ratel Pro only, in the woods, the background was hardly visible without additional light 😑 it was very hard to find the landing place at aim for it.


PS: I got inspired with Hoarder Sam's video 😎

Let's take flight together and elevate the world of FPV drones to new heights.
