  • INAV Braking Mode for multirotors

    Flying with a multirotor drone with INAV always had a problem: braking. When you were flying fast and then release the stick, a drone was not braking very fast, then it was going back to the place where you released the sticks. Rubberbanding. Irritating. Over the time there were at least 2 attempts to fix…

  • Betalight 3.3 and Kalman filter (BiQuad+FIR2 to be precise) situation

    Betaflight 3.3 RC1 Betaflight is at the end of next release cycle. Betaflight 3.3 RC1 has been released only 2 days ago and that brought us a (not) Kalman filter! Long story short: Raceflight was using Kalman (Fast Kalman Filter – FKF) RS2K left RF and brought FKF to Betalight Betaflight did some changes and…

  • First glance at Armattan Rooster FPV quadcopter drone frame

    After flying chinesium (XMR250, Reptile X4R 220, Martian II) and frames from DemonRC I’ve decided to switch to completely different brand. My choice is Armattan Rooster, the newest freestyle frame from Armattan. Rooster arrived few days ago, and this is what I can say about it before putting all the stuff into it: sunken nuts…

  • Realacc UXII circular polarized 5.8GHz FPV antenna – Lumenier AXII chinesium clone

    Cloners gonna clone and chinesium keeps being chinesium! It did not take long for Banggood / Realacc to clone Lumenier AXII FPV antennas and call them Realacc UXII circular polarized FPV antenna. Coincidence? I do not think so. I've ordered few of those in December, they arrived last week and this is what came in…

  • Crossbow LRS: ready for next tests

    Looks like I was able to solve all major known problems with my DIY long range radio system Crossbow. I'm writing known, since no idea what lies beneath… Anyhow… What changed? Quite a lot: I've extended Arduino-LoRa library with ability to transfer full packet in single SPI transaction. Right now, each read of write to…

This time, I've looked into last 3 months of the year 2017: October, November, and December. Important, this is…

  • How to wind an electric brushless outrunner motor with dLRK winding schema, part 2

    My memory is not as good as it used to be. I just realized, that third part of my motor winding series was not yet announced over here. So here we go… In this video I terminate motor into Delta pattern and do first test of freshly winded motor.

  • Crossbow LRS: first live test that is almost a success

    Finally, much later than I originally expected, Crossbow LRS, my DIY medium range RC radio link was used to control something that flies. Not much, and not far. It was only my experimental 6″ GPS Racer quadcopter. And I reached only 350m. Small steps, I had no intention to beat and records after all. Just…
