  • Cleanflight, what is up with you?

    Those are my personal thought on the topic. If you do not aggree, it is fine, I will not argue or discuss. You have a right you your oppinion, I have a right to mine… When I entered multirotor hobby about 2 years ago, Cleanflight was The Flight Controller software to get. OpenPilot was about…

  • How-to: Eachine E010 Tiny Whoop

    It’s not easy to fly FPV during winter weather. You either have to have weather proof quadcopter (airplane) or fly indoors. And it’s not simple to find a good, big and cheap place to fly FPV in. But, how about flying FPV in a living room?

  • Programming ESP8266 with Arduino IDE

    One of the best things about ESP8266 ESP-01 WiFi modules is that they can be programmedusing popular and well known Arduino IDE and act as stand alone board with WiFicapabilities. Thanks to ESP8266 group process of integrating ESP8266 and Arduino IDEis pretty simple. First step is to add http://arduino.esp8266.com/stable/package_esp8266com_index.json to Additional Boards Manager URLs in…

  • INAV: Launch mode video tutorial

    One of the best new features of INAV 1.4 was Launch assistant mode (NAV LAUNCH). It greatly simplified the process of hand launching a fixed wing. All you had to do was to throw it into the air. INAV detected the throw, engaged motor(s) and stabilized flight and kept constant climb rate in the initial…

  • Flip32 F4 and Airbot F4 Software Serial

    When STM32F4 based flight controllers made its way to the world of MultiWii derivatives (Cleanflight and whole family), all I think all developers assumed that SoftwareSerial feature will not be needed on those boards. Why it should be? STM32F4 has enough hardware UARTs to satisfy everyones needs. Unfortunately, live had it’s own point of view…

  • Yaw unstable at full throttle

    Last weekend I’ve experienced quite serious problem with Reptile X4R 220 racing quadcopter: on full throttle quad was loosing stability. At first, it was starting to drift yaw to the right. Then, if throttle was not lowered, roll and pitch was also becoming unstable and quad was doing crazy things in the air. I do…

  • Marabou Stork: Depron airplanes do not last long

    Marabou Stork, my Depron FPV airplane had a bad luck. Few weeks ago, when I was testing development version of INAV, it crashed during take off. Poor accelerometer calibration combined with a software bug resulted in heavy roll 2 meters above ground. As a result, whole front section was smashed. Everything else more less survived.…

  • UART1 and PPM on Airbot F4 / Flip32 F4 Flight Controllers

    Today I’ve discovered another small but irritation limitation of Airbot F4 / Flip32 F4 also known as CC3D REVO for unknown reason. Looks like, by default, this board is unable to share UART1 RX line and PPM input. So, if you would like to connect, for example, OSD or GPS to UART1, you would have…

  • How much power flight controller consumes?

    Year after year flight controllers grow stronger, faster, more powerful. Three years ago we had MultiWii running Arduino. Two years ago it was Naze32 with STM32F1. Year ago it was SPRacingF3 with SMT32F3. This year it is something with STM32F4. Is there a price is power consumption to pay? Should we start using stronger BECs?…
