Currently, there are 2 types of MCU from Espressif on the market: ESP8266 from 2014, ESP32 from 2016 and ESP32-S2 that debuted in the second half of 2019. Although ESP32-S2 is not yet very popular, it is expected it will replace ESP8266 as a cheaper, more powerful and more secure alternative in the upcoming years.…

INAV can use various sensors to fly drones and airplanes: gyroscopes, accelerometer, magnetometers, barometers, GPS, OpFlow, rangefinders, and airspeed. Some of them required some are recommended and some are a purely optional piece of hardware. Here is the full list: INAV Sensors: Gyroscope and accelerometer Required. The flight controller will not boot without a gyroscope…

Believe it or not, but Mozilla Firefox (back in the days when it was still called Mozilla Firebird) was the first modern web browser. Even in early beta stages, it was so much better than Internet Explorer, that almost anybody who tried it, dropped IE and just used Firefox instead. Of course, over the year,…

I’m not shy to switch to a new web browser every few months when needed. I was one of the first users or Firefox when it was still named Firebird (yes, I’m that old). I abandoned Internet explorer without looking back. After all, it was such a bad browser.

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…

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…

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…

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…
