  • How FPV looked 2.5 years ago…

    A few days ago I went back in time. Or to be more precise I started to browse my photo archive. And I’ve found pictures of my first FPV quadcopter… Oh my… ancient times… Doesn’t it look awkward? At least a little… But this baby was pretty cool to think about it. At least when…

  • 3D printed racing drone, part 1

    I’ve been pretty busy last 2 weeks. Among other things, I’ve started to design 3D printed racing drone frame. I’m fully aware there are plenty designs available on Thingiverse, but almost all of them forgets that plastic filament is not carbon fiber laminate and what works well with carbon, will fail with filament. So, I…

  • DIY RC radio link: the problem of protocols

    So, you want to build your own RC radio system? Long range maybe? Cool, I want to do it too. Since I’m pretty deep in that topic now, I can give you a hint or two. For example, have you thought about a protocol your radio system will implement? Or rather should I say: protocols?…

  • Betaflight Dynamic Filtering Explained

    Betaflight Dynamic Filtering Explained

    Betaflight works as great as it does thanks to amazing gyro noise filtering. Without it, flight would be shaky as hell. The core element of gyro noise filtering are Dynamic Filters. In this article let’s talk about how they work The problem of noise Gyro has a nasty tendency to pick up a lot of…

  • Understanding Dterm: how Dterm really works

    I will be very honest: until very recently I did not really understood how PID controller’s Dterm really works. Yes, something with dampening, something with “looking into future”, bla bla bla. But the reason for not understanding was because I was overthinking it. There is no “magic” only simple mathematics and few basic concepts which…

  • Very custom FPV quadcopter for my daughter

    When few months ago my older daughter (10 years old) started to express interest in FPV quadcopters, I was both happy and concerned. Happy, since I would have someone to fly with. Concerned, since she has no idea how to fly, I do not have a quadcopter for her and there is a big chance…

  • How to connect APM Airspeed Sensor (Pitot Tube) to INAV

    Recently released INAV 1.7.2 introduced new hardware support: analog airspeed sensors. I’ve written new but it is new only to INAV. Analog airspeed sensors aka APM Pitot Tubes aka Ardupilot Airspeed Meter and one the market for years. And they are cheap. By cheap, I mean below $30. And until recently they were usable only…
