What is a PID controller and how it works?
The whole FPV hobby, and especially multirotor drones, work only thanks to control theory and PID controllers. They are the only thing that separates chaos and immediate flip-over from a stable flight. A regular multirotor has at least 3 PID controllers. If you enable any mode with self-leveling, the number goes to 6. Any GPS…

A very cool, futuristic looking, 3D printed quadcopter frame
I love this part of me being a creator and an influencer, where I can show you some amazing things created by other people. And today, the joy is double, because it is an extremely cool frame designed by a guy from Spain that goes under the nickname of Micrathene FPV. What it is? Well,…

Betaflight vs EmuFlight vs INAV
Which flight controller software flies better out of the box? You know, the stock, default settings, no tuning. Just flash and fly. Betaflight, INAV or maybe EmuFlight? I decided to test it on one of my 5-inch FPV drones and compare: Betaflight vs INAV, Betaflight vs EmuFlight and EmuFlight vs INAV. The results are divided…

What is EmuFlight?
Here is a short story of what is EmuFlight, how it differs from Betaflight and should you even care? To answer the question. Yes, you might want to take a look at it. It is different enough from Betaflight to consider it as a separate flight controller. And some people say it really fly great…

EmuFlight and INAV Matrix Filter
Matrix Filter will have its premiere together with EmuFlight 0.3.0 and INAV 2.5. Which of those two will happen first is still unknown. After originally developing Matrix Filter for INAV, I also ported it to EmuFlight code and already some time ago they accepted my code proposal and merged it. You have to admit, that…

A brief history of a flight controller – From MultiWii to Betaflight and beyond
I will tell you the history of probably the most successful family of Open Source flight controllers: MultiWii that continues its life today as Betaflight, EmuFlight, and INAV. Other families like OpenPilot were not that successful and practically died. On the other hand, the history of ArduPilot is not that interesting and we can leave…

INAV on rovers, boats, crawlers, tanks and other ground vehicles
What can INAV do? Well…. it can fly your multirotor drone and a fixed-wing airplane. And it can do it pretty nicely! Unfortunately, that is all it can do. Now, at least. Every year or so, I’m building an RC airboat and always wanted to build a rover based on some kind of an RC…

Was I disqualified from Betaflight?
The best way to fight with haters and different types of fanboys with whom you do not agree with is to ignore then. Just like that: do not feed the trolls, it makes no sense. Sometimes, tho, it’s so hilartious… Like today I learned that I was disqualified from… Yes, from what? Betaflight? Some other…
