    Diatone Hey Tina Whoop162 with FalcoX

    I will be very frank with you: I do not like those tiny whoops. You know, 2″ and smaller propellers, plastic frame, a camera on top. You know, those almost cheapest FPV drones you can get. I’m saying that builds like BetaFPV 65X or Emax Tinyhawk are bad. I just do not like to fly…

  • STM32 F1, F3, F4, G4, F7 and H7 flight controllers

    STM32 F1, F3, F4, G4, F7 and H7 flight controllers

    Currently, almost all flight controllers we use on our multirotor FPV drones and airplanes are powered by microcontrollers from an STM32 family. When we say about flight controller families or generations, we refer to them by the family of the MCU. For example: F1 flight controllers are no longer supported or You should get F7…

  • Betaflight 4.2 Gyro, Looptime and Gyro Stage 2 Lowpass Filter

    Betaflight 4.2 brings some very important changes to how various tasks are processed. Especially how gyro,m filtering and PID loop are working together. First of all, the gyro is sampled always at the gyro native speed. This means, MPU6000 will be sampled at 8kHz. Always. At the same time, PID and filtering are working as…

  • The best RC radio transmitters for Q2 2020

    The best RC radio transmitters for Q2 2020

    The last year was a good year in terms of new radio transmitters. It’s no longer a choice between FlySky and FrSky. We have new players and new products. Below is my, very subjective, overview of the most interesting radios on the market. Still the best – FrSky X10S Horus In my very personal opinion,…

  • All the INAV sensors: are they required or optional?

    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…

  • 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,…

  • 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…
