  • Hands on: Omnibus F7 Flight Controller

    Thanks to Airbot I got my hands on a new STM32 F7 flight controller: Omnibus F7. Before we proceed, small note. I am a huge fan of F7 flight controllers. In a year, they will be a main line of high performance FC on the market. STM32F7 with built-in UART inverters solves so many issues…

  • Hardware revisions of Omnibus F4 flight controllers

    Airbot Omnibus F4 series is one of my favorite flight controllers. Two of my quads are flying thanks to them. They might not be the best or the famous ones, but they get the job done. And that is what counts. Unfortunately, they are not free of faults (and what is?) and each next revision…

  • GPS Racer: worklog #7 – flying at night

    Like promised, I took GPS Racer equipped with night vision camera RunCam Night Eagle and IR projectors for a night flight. And it worked. Not as good as I expected, but worked. RunCam Night Eagle is sensitive enough to fly at night. Just like that. As long as there is at least some light, you…

  • Pitot tube is coming to INAV

    One of the things that INAV was missing, was a decent support for Pitot tubes, or more generally speaking, airspeed sensors. Autonomous flight, or landing, without knowledge about airspeed can easily lead to a stall. Stall can lead to crash. A crash leads to rebuild. Rebuild of big airplane is a nightmare. Although, for some…

  • GPS Racer: worklog #6

    I have to admit, I have a talent for building ugly looking quadcopters and airplanes. But this is a step forward. This is the ugliest quadcopter I’ve ever seen… just look at it… So ugly, that almost beautiful… Those two “eyes” are IR projectors and that almost not visible FPV camera is RunCam Night Eagle……

  • Gyroscope and filtering video tutorial – Episode 3

    In this episode I talk about: How to analyze Blackbox log for gyro noise How to find frequencies for gyro and Dterm notch filters in INAV, Cleanflight and Betaflight

  • GPS Racer: worklog #5

    I’ve finally decided to make a decent use of my GPS Racer quadcopter. Until now, I mainly used it to test new things for INAV and that is more less all. RunCam Owl Plus FPV camera turned out to be non-flyable in the night, so I’ve decided to go one step further… RunCam Night Eagle…

  • USBasp driver for Windows 10 – Working solution

    Yesterday I’ve spent like 2 hours fighting to make USBasp ISP programmer work under Windows 10 64bit. Seriously, that was like some kind of nightmare that turned into a comedy. All web pages that I’ve found suggested following procedure: Unfortunately, in my case all attempts failed miserably. All I was getting from avrdude was I’ve…

  • Depron Airboat Worklog #2

    Next week passed and Depron Airboat is almost ready. Almost, since it still needs some finishing and I’m missing a BEC. Turned out that total power usage of one 9g servo and FrSky X4R receiver is slightly too high to just use single LM7805. 350mA during servo movement means more that 2W of heat ((12-5)…
