Matek 4 in 1 ESC – STM32F4, SerialShot and no BLHeli
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 TBS Source One
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…

How much does a propeller weight? Mass vs. moment of inertia
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…

3D printed FPV tricopter drone
Who could have imagined that tricopters can be so much fun? For sure they are interesting devices that lost a lot of "market" when quadcopters gained extra torque and plenty of reaction moment to do fast yaw turns. Almost no one flies them now. Too bad… And good luck if you want to buy a…

Matek F722-SE – brand new flight controller that brings STM32F7 closer to the needs of many
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…
