With this short article I would like to initiate new series: Fixed Wing 101 where I will describe some basic concepts connected with fixed wing airplanes that should help beginners to enter the hobby. Today: why airplanes fly and why, from time to time, they fall down from the sky… Lift Airplanes fly thanks to…

Another new feature of upcoming INAV 1.6 (BTW, INAV 1.6 ALPHA-1 has just been released) is brand new PID controller for fixed wings. I repeat: this new controller is used only on fixed wings, multirotors are not affected. So, what is new about this new PID controller? First of all, it is no longer a…

Upcoming INAV 1.6, and INAV Configurator 1.6 will bring many important changes. I will try to cover most of them in a next few days, beginning with Presets. Because INAV can run very wide spectrum of aircrafts, it suffers a penalty of very general default values. Different frame sizes, propellers, multirotors, airplanes, flying wings. It…

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…

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?

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…

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…

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…

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…
