BetaFlight 4.3 Tuning Notes (currently in draft but things are warming up with the release)

https://github.com/betaflight/betaflight...ning-Notes

Wow some nice new features.

Did I miss it? I don’t see anything about being able to choose baro or gps altitude.

Quote:Most importantly, the slider positions are now stored in the flight controller. Slider settings can be changed via the OSD or Lua at the field, and those changes will be reflected in Configuator when you next connect up. This really makes on-field tuning a lot quicker and easier.

NICE!
This is something I have been waiting for.  Being able to adjust the sliders via OSD in between packs to test the difference.  I don't have a laptop I can bring to the field, so I have only been able to manually adjust PIDs by numbers, or by using Presets and trying to remember the changes you made between the 3.
Being able to use sliders between packs will make tuning a lot more fun, and a lot easier to feel the difference being able to do it quickly between packs.

This already exists in Betaflight 4.2 via CLI but not via the configurator:



If you set Default then the calculations take into account both GPS and Barometer altitude (source: https://github.com/betaflight/betaflight/pull/8127):

estimatedAltitudeCm = gpsAlt * gpsTrust + baroAlt * (1 - gpsTrust);

This can result in bad altitude calculations if you don't have a GPS lock and take off.

The person testing the presets prior to the 4.3 release is Ivan 'limon' Efimov who is a Russian born (living now in US) who has build the Open Racer frame (open source on thingiverse) and is a good FPV race pilot. 

I am happy for the presets functionality more than anything else.

Yeah that sounds great, too!  I normally don't bother upgrading versions of BF if it is working good on my quad, unless it is adding something big like Bi-Directional DShot, ect.

This will be 1 upgrade I definitely do, just for these tuning changes.  I am trying to learn more about the software/firmware side of things, and learn how to tune.  It all seemed so complex and over my head when I started, but now it's starting to make sense, and with these quality-of-life tuning changes and simplifying of tuning it is a great step in the right direction for people like me trying to wrap our heads around PIDs and rates ect.
