  • INAV fw_iterm_limit_stick_position – keep the Iterm under control

    PIFF controller in INAV is with us for quite some time now. And it’s working just fine, much better than classic PID when it comes down to airplanes. There is, or rather was, a small problem tho: Iterm. When P and FF components of the controller are not tuned, Iterm might do crazy things that…

  • Put a gimbal on a 7-inch quadcopter drone

    My 7-inch Source One got an interesting upgrade: instead of static GoPro Session bracket, I’ve put a gimbal on her. She might have got slightly heavier, but gimbal allows to take amazing shoots not. And it’s detachable! Sure, it looks awkward a little but gets the job done. The gimbal… the gimbal is crazy cheap…

  • Everything you want to know about Betaflight Iterm Relax

    Let’s pretend I have a whiteboard and do a quick explanation what Iterm is and how Iterm Relax is helping you to fly better! what is Iterm like I in PID why we need Iterm why Iterm has a tendency to windup why Iterm has to be constrained how Iterm Relax helps to limit the…

  • Matek 4 in 1 ESC – STM32F4, SerialShot and no BLHeli

    I have to say I take great pleasure in installing this very early prototype of Matek 4-in-1 ESC in one of my mini quads and taking it for a flight. It’s kind of cool to know I was one of the first ones in the world that got it, installed it and tested it. Nice…

  • Race Day Quads Mach 1 with EMAX RS2 2306 2400KV

    This year my friends and I stared a local FPV drone racing series. Nothing serious, just a couple of guys meeting once in a while and measuring times over the track. 100% amateur thing. After the second race, I’ve realized that I do not have a drone designed for racing: more than 400g without a…

  • Dualcopters are the dead end of evolution

    I’m done with coaxial dualcopters. It’s a dead end of evolution: loud, not efficient, hard to tune, hard to fly. If you still want to make one, here is my 3D printed dualcopter on Thingiverse. Maybe you will have more luck than me…

  • This is my 7-inch TBS Source One

    This is my 7-inch version of TBS Source One quadcopter frame. So far, so good, Source One is really tough and stiff frame so all the problems with resonance and oscillations in flight should be over. And looks like they are over. It might sound like a good old V8 engine but flies smooth. And…

  • How to setup INAV on a flying wing – video tutorial – GPS, Baro and Compass

    Do you need a barometer on a flying wing with INAV? Do you need a compass/magnetometer on a flying wing? How to set up a GPS unit and which protocol should you use? Do advanced tuning and set up a return to home, banking angles, landing procedures etc. Configure the most important GPS related flight…
