RunCam Split very late pseudo review: it’s not good
I own RunCam Split. I own it for like 2 months now, and it’s still in a box. Never connected, never really used. And in the meantime, I’ve build 2 mini quads are rebuild third. Why is that? Is there something wrong withthis camera that I’m not using it anywhere? And not planning to? Let’s…

Betaflight Dynamic Filtering Explained

Very custom FPV quadcopter for my daughter
When few months ago my older daughter (10 years old) started to express interest in FPV quadcopters, I was both happy and concerned. Happy, since I would have someone to fly with. Concerned, since she has no idea how to fly, I do not have a quadcopter for her and there is a big chance…

GPS Racer: worklog #8 – sonar test platform
I honestly admit, that my 6″ quad (codename GPS Racer) was never very pretty. It was just ugly with that GPS tower on the front.

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…

Hardware revisions of Omnibus F4 flight controllers
The Omnibus F4 series is one of my favorite flight controllers. Two of my quads are flying thanks to them. They might not be the best or the famous ones, but they get the job done. And that is what counts. Unfortunately, they are not free of faults (and what is?) and each next revision…
