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.

Small, light, quite well thought through. Here is how I’ve built my ZOHD Nano Talon, small FPV airplane using following components: Airplane: ZOHD Nano Talon PNF Flight controller: Matek F405-Wing Radio: FrSky R9 Slim long range receiver Motor: T-Motor F80 1900KV FPV transmitter: AKK X2-Ultimate 1200mW Camera: RunCam Eagle 2 GPS: Beitian BN-880 Software: INAV…

We have finally done it! The first release candidate for INAV 2.0 is open for download. You can get it together with INAV Configurator 2.0 from GitHub. What changed? The list is very very long and to be honest it is probably the biggest INAV release ever. There are over 200 tickets connected with INAV…
