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…

18650 Lithium-Ion batteries are the workhorse of modern consumer (and not only consumer) technology. If you have anything that is battery operated and there is a “Li-Ion” mark anywhere on it, probably it is powered by 18650 Li-Ion battery. Laptop batteries, cordless drills, cordless tools, e-cigarettes. All of them (probably) have 18650 cells inside. In…

I am fully aware that Reptile S800 Sky Shadow EPP flying wing is not a fresh topic. It is on the market for much more than a year and the internet is full of reviews. So it will not be a review. I will only say that I like S800 very much. Much much, much…

Betaflight 3.5 is just around a corner and it brings new cool things. There is no more Dterm setpoint weight and Dterm setpoint transition (relaxation ratio). They all were replaced by easier to understand Derivative and Feedforward (Feed Forward when you refer to the control theory tho). Betaflight Derivative and Feedforward parameters are the new…

This is one of the most frequently reported things about every new version of INAV Configurator: from time to time, it starts minimized and it can not be made visible. It is a bugger connected with a fact that INAV Configurator does not have an installer. It’s just “download and run” and after releasing a…

After a maiden, I’m not very happy… Nano Talon is quiet, efficient and small. But flight performance is not overwhelming. Even quite far good. Let’s say it’s OK. But the worst thing is that I crashed mine due to hardware failure. ZOHD, where is quality control? This should not happen.
