What happens when multirotor world meets flying wings? Flying ZM250 without arms is born. Today we will take a look at a new example of German Engineering: Flybot Flux Freestyle FPV Flying Wing Bottom line is that Flybot Flux is just an amazing flying wing!

Weather like this happens only a few times a year: raising fog, low sun and another layer of clouds… And very little wind. To be honest, when I went to the “airfield” I did not expect to use my Ritewing Mini Drak at all. The fog was too dense and too low. But then it…

Let’s measure power output from Eachine TX805 that is supposed to be up to 800mW. Well, it is not. It matches the specification only at 200mW and 800mW is just not there. But, well, it’s only $16 and when used at 200mW or 500mW it works quite well. RF power meter can be purchased for…

INAV 2.0 introduced two new OSD modes: Map and Radar. Here is a video describing what are Radar and Map modes in INAV and how you can use them.

What to do when Matek F722-STD flight controller is not booting without connected battery and connection from Configurator is not working? Simple, power GPS and magnetometer from a different pad.
