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…

How to choose motors for drones – especially 7-inch FPV quadcopters
