  • 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

    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…

  • FrSky ACCST 2.0.0 "important" firmware update for all receivers, radios and transmitters

    FrSky does not sleep, or rather woke up, and after years of not touching the topic, released an “important” update of ACCST 2.4GHz protocol for all the compatible 2.4GHz receivers, transmitter modules, and radios: X9D Taranis, Q X7 Taranis, X10/X10S Horus, X8R, X4R, X4R-SB, XM, R-XSR, XJT and so on. What changed in ACCST 2.0.0?…

  • FrSky R-XSR pinout

  • FrSky Taranis Q X7 and X7S – is it still worthy?

    FrSky Taranis QX7 appeared on the market a few years ago and got quite a lot of popularity in its time. There were reasons for that:

  • Dalprop Nepal N1 5" propellers

    This weekend, thanks to Foxeer, I had an opportunity to test flight new Dalprop freestyle props: Nepal N1. Although the name is a puzzle for me, I’m pretty sure Dalprop Nepal N1 might make some stirr!

  • INAV and DJI HD FPV system – there is a light at the end of the tunnel

    When DJI did not decide to add INAV and Ardupilot to the list of the supported flight controller for the HD FPV system, some people were, at least, disappointed. Long story short: DJI OSD works only with Betaflight. Period. Until today, DJI avoids the answer to the question if INAV and Ardupilot will be supported.…
