Let’s pretend I have a whiteboard and do a quick explanation what Iterm is and how Iterm Relax is helping you to fly better! what is Iterm like I in PID why we need Iterm why Iterm has a tendency to windup why Iterm has to be constrained how Iterm Relax helps to limit the…

I have to say I take great pleasure in installing this very early prototype of Matek 4-in-1 ESC in one of my mini quads and taking it for a flight. It’s kind of cool to know I was one of the first ones in the world that got it, installed it and tested it. Nice…

This is my 7-inch version of TBS Source One quadcopter frame. So far, so good, Source One is really tough and stiff frame so all the problems with resonance and oscillations in flight should be over. And looks like they are over. It might sound like a good old V8 engine but flies smooth. And…

Do you need a barometer on a flying wing with INAV? Do you need a compass/magnetometer on a flying wing? How to set up a GPS unit and which protocol should you use? Do advanced tuning and set up a return to home, banking angles, landing procedures etc. Configure the most important GPS related flight…

You should not trust a guy on YouTube that says that he knows it all OpenTX “no signal” is not the best failsafe setting when FrSky S.BUS devices are used and why Than “Hold” failsafe setting might actually be a better option when S.BUS is used How to setup Failsafe in INAV to have the…

How often, when you watched or read a brushless motor review you’ve heard a sentence like “this motor will not have any problem spinning a heavy propeller” or “this motor is designed for light propellers”. Or “this is a very light propeller”. But what does that really mean? Thanks to our good friend Sir Isaac…

At the beginning of 2018 I’ve stated that Matek F722-STD is the first F7 flight controller that makes sense. Today, I have in front of me I have the first F7 flight controller that has all you need (and more) when 4-in-1 ESC is not what you are looking for. It is Matek F722-SE! STM32F722…

I have to honestly admit, up to the beginning of 2018 summer I was rather against 4-in-1 ESCs and flight controllers combos. The reason was quite simple: 4-in-1 were a rather new thing, had a tendency to burn without a reason and were quite expensive. Pretty much a normal state of a new technology. In…

The next major release of Betaflight will be 4.0 with new and improved Dynamic Filtering. For now, today I only did a quick test of Betaflight 4.0 running on my TBS Source One 7-inch FPV drone. No tuning, no playing with settings. I only flashed, set modes and radio and that’s all. I pretty much…
