ArteryTek AT32 Flight Controller – NeutronRC F435
OK, I’m kind of hyped with this! What you see on the image looks like an any other flight controller, right? Looks again! It’s not STM32 but ArteryTek AT32! And F435 as a bonus 😉 With the continuing chip shortage supply of STM32 is limited and prices high. Maybe have an alternative source of MCUs…

Bidirectional DSHOT & RPM Filtering – Is It Really Necessary?
There is a group of people who think that the RPM Filter is the best thing to happen to flight controllers and quadcopters since the sliced bread. Perhaps. I’m more inclined to believe that RPM Filter is just an example of good functionality. But it will not be about that, so let’s go back to…

A brief history of a flight controller – From MultiWii to Betaflight and beyond
I will tell you the history of probably the most successful family of Open Source flight controllers: MultiWii that continues its life today as Betaflight, EmuFlight, and INAV. Other families like OpenPilot were not that successful and practically died. On the other hand, the history of ArduPilot is not that interesting and we can leave…

Betaflight Dynamic Filtering Explained
Betaflight works as great as it does thanks to amazing gyro noise filtering. Without it, flight would be shaky as hell. The core element of gyro noise filtering are Dynamic Filters. In this article let’s talk about how they work The problem of noise Gyro has a nasty tendency to pick up a lot of…

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…

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 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…
