Autotune (or Auto Tune) that is present in INAV for quite a long time is a working solution for tuning PID (or rather PIFF) controller used by INAV on fixed wings (all airplanes, flying wings). Not like all the attempts designed for multirotors, this one actually works.
INAV Autotune can be used on any airplane and is fairly simple to use as long as you follow a few simple steps:
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 flux.
My favorite solution lately is a flux pen. Like Stannol x32-10i
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 new version, we can not delete stored data during install. Since there is no install process.
Your magnetometer/compass is not working with INAV? Is the sensor red in Configurator? You are not the only one… Not only most popular compass HMC5883l is discontinued and what you get are Chinese clones, chip labeled 5883 might not be HMC5883l but something completely different. And I2C bus is very very picky and likes to give up on you….
This is how you might fix your problems: add pullup resistors for I2C SCL and SDA lines and/or lower i2c_speed…
Google finally did what they announced last year: Chrome Packaged Apps for Windows, Mac, and Linux are dead. OK, maybe not 100% dead, but they were removed from search and browse in Chrome Web Store. If you still have link, you can install (no idea for how long tho).
So, how to live with that? Our hobby is driven by Chrome Packaged Apps. Betaflight Configurator, INAV Configurator and Cleanflight Configurator are all Chrome Packaged Apps. Did we lose the ability to set up our drones? Luckily no. Thanks to fantastic project NW.js, chrome apps can be packed together with Chromium and distributed as a single file without dependencies. I've prepared a short video how to install Standalone Betaflight Configurator, for INAV it's the same procedure. And for Cleanflight… well… Cleanflight is dead. Or rather dying…
