    How to use INAV Autotune

    Autotune is a feature in the INAV flight controller firmware that helps automatically tune PID settings for fixed-wing aircraft. It simplifies the tuning process by adjusting roll, pitch, and yaw rates based on flight behavior. How It Works: Autotune (or Auto Tune) that is present in INAV for quite a long time is a working…

  • Two things that you HAVE TO change in Betaflight (3.4 and 3.5)

    After weekend tests of Betaflight 3.5 and some discussions with Betaflight developers, here are two things you have to (yes, have to) change in Betaflight 3.4 and 3.5 if you did not did that yet. Worth to do it!

  • What is Betaflight 3.5 Feedforward and how to use it

    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…

  • Soldering, rosin, flux and a Stannol x32-10i flux pen

    If you really really want, you can solder without flux. But it is a painful experience. Almost all modern solders have flux integrated into its core. And as long as you do not try to solder anything big, it’s enough. Of course, sometimes it is not enough and you have to help yourself with additional…

  • INAV Configurator starts minimized and how to fix it

    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…

  • How to use INAV Autotrim function – since you should do it

    How to use INAV Autotrim function – since you should do it

    INAV Autotrim is a feature in the INAV flight controller firmware that helps automatically adjust servo midpoints for fixed-wing aircraft. It ensures that the control surfaces are properly trimmed for level flight, making manual mode transitions smoother. This is one of the most useful INAV functions for fixed wings! Servo autotrim solves the problem of…

  • ZOHD Nano Talon FPV Airplane, part 2

    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.

  • DIY Dipole for Crossfire and FrSky R9M

    Details for halfwave dipole for an 868MHz band are quite simple: two 0.8mm copper wires (used for welding) cut to 77mm and solder to the end of coax cable. Here I’ve used RG178 put that thing into a 3D printed casing put antenna tubes around wires. I got mine from here: http://bit.ly/2vHHqDk glue everything together…

  • DIY Moxon antenna for TBS Crossfire and FrSky R9M

    Moxon antenna in layman terms, it’s probably a simplest linearly polarized directional antenna. It’s like a bent halfwave dipole with a bent reflector in a back. Think about it as a very simplified Yagi antenna. It does not have much gain but has very good backward rejection. And thank’s to a simplicity, Moxon is super…
