Omnibus F7 Flight Controller
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 STM32 F4 boards…

Flip32 F4 / Airbot F4 : Pinout
There is very little reliable information about Flip32 F4 / Airbot F4 on the internet, so I’ve decided to fix it. Today, pinout map for Flip32 F4 (Betaflight 3.0.1) and some additional notes: Betaflight 3: use REVO target

PID looptime: why it is not only about frequency
Last 18 months was an extremely good period of time for all mini-quad enthusiasts. Progress, hardware and software both, was just incredible. Who could have guessed that in less than 2 years mini-quads will evolve into main group of drones with such excellent flight characteristics. Just take a look at looptime. When I entered the…

How to install and configure Betaflight
Latest Betaflight 3.0 is a new quality for flight controller software. It brings many new, cool, features comparing to previous versions. If you fly mini-quad or micro-quad, you have to check what Betaflight 3 has to offer. This tutorial will show how to install Betaflight 3 and how to configure it so mini-quad can go…

How to measure gyro noise frequency with Blackbox
Betaflight (and INAV) lowpass filter tuning can be a hard thing to do if you have not idea what is noise frequency you want to cancel. Sure, you can blind test or read tutorials. But what if I tell you, you can measure it quite precisely using only Blackbox logs? Or measure rotation speed of…

How to tune PID I-term on a FPV drone
With this entry I want to initiate short series of articles showing how to tune multirotor / quadcopter PID controller. Let’s call it a continuation of Blackbox series, but this time I will not relay only on Blackbox data. Yes, I will show few examples how given scenarios looks on Blackbox logs, but all steps…

WiFi telemetry for Cleanflight with EZ-GUI and ESP8266
Some time ago I have written a tutorial how to setup Bluetooth based telemetry link between Cleanflight and PC or smartphone. It’s simple and it works. But it has some disadvantages. For example, connection is very very slow and has a limited range: up to 10 meters. While it is enough to change PIDs before…

Smartport telemetry for Betaflight
With their latest transmitters and receivers FrSky changed telemetry protocol. XJT module, Taranis radios, X8R, X4R and X4RSB are using SmartPort telemetry protocol. And that creates few problems. First of all, SmartPort is a serial protocol. That means, flight controller has to have free serial port to connect S.Port device. Second of all, TX and…
