Let’s take a look at the new flight controller from Matek designed for airplanes: Matek F411-Wing. Comparing to its older brother (or sister or just a sibling) Matek F405-Wing it is much smaller, lighter and lacks many of the features: 2 UARTs instead of 6 5 servos instead of 7 no SD card slot 3…

When FrSky R9M long range transmitter and FrSky R9 receiver series started to pop up some time ago, there was a lot of speculations “it is any good?” “is it a Team Black Sheep Crossfire killer” “cheap Crossfire alternative?”. In time, new firmware started to appear, new receivers and so on. And oh yes, EU…

FrSky makes radios. Good and very good. Dominates the market. Taranis, Horus and all of them TBS makes bloody good long range 868/915MHz long-range radio system called Crossfire that is commonly used by FrSky radio users FrSky tries to make its own 868/915MHz long-range system called R9 FrSky releases new R9 firmware called Flex, new…

I like my 7-inch endurance FPV drone. Maybe it does not flies super smooth yet, but slowly I’m getting there. The best move was probably to replace HQProp 7×3.5×3 V1S propellers with Gemfan 7×4.2. Fantastic propellers those Gemfans… The common cranes (Grus grus) in a middle of the video really could not decide if they…

SD cards are cool: cheap, reliable, a lot of space and you can remove them from the drone and read on a PC. But sometimes, it’s really hard to take them out. Either SD slot is in a strange place, or FC is oriented in a strange way or an FC designer has put an…

Oh boy, I had high hopes for iRangeX iRX-IR8M. Got disappointed badly. So, to make it a little better, let’s get our hands dirty and install an external antenna using an SMA pigtail. Maybe it will make this not so cheap s**t a little better! So let’s have a nice talk in a workshop and…

You might say that UBLOX NEO-M8N (Beitian BN-880 for example) is the workhorse on INAV and other drones with GPS functions. It is reliable, well know and proven. But it is also big and heavy. So why not try something new? Matek did tried something new and just provided me with two brand new GPS…

INAV 2.0: Wind estimator. What does it do? Tries to estimate the speed of the wind (obviously) as well as wind direction. Let’s be honest, it’s experimental and relays only on the difference of predicted and actual flight path. So do not even try to think it will give accurate measures. But my tries says…
