Introducing: Betaflight 4.4.0-RC4

We are getting close Flyers!

This release also brings a few changes to the cloud build, the biggest of which is that if you are using RC4 of the configurator, there should be no more "red errors" when applying custom defaults and resetting to the "defaults". These defaults are now customised based on the build. There may be a few items we have missed so any errors that come up please post in the #cloud-build-issues in our Discord or log an issue here.

IMPORTANT: Make sure you install and use the latest version of the Betaflight Configurator (10.9) before updating your firmware.

Please read these important introductory notes:

  1. After updating to Betaflight 4.4.0-RC4, you MUST use the latest 10.9 Betaflight Configurator. Earlier configurator versions will not work properly with 4.4 releases.

  2. 4.4 has a new Cloud Building System. This is design to extend the life of smaller flash sized MCUs (F411 and F722) based boards. You need to enable the various options in the build, before selecting "Load Firmware Online" within the configurator. It is super simple, but just be aware that unless you have selected the option for your firmware it will not be available once you flash the board. Don't stress, if you miss an option, just request a new build! :)

  3. HD OSD support has been added. This is not currently supported by HD Zero, but some effort there is in the works so watch this space.

  4. Check all your settings carefully before arming for the first time. Check PIDs, Filters, Rates, motor configuration and motor rotation. For the first flights, arm in a safe place, fly gently, and look out for any setup or build issues.

Betaflight has a presence on the Discord messaging platform - and this is the primary location for support, questions and discussions. Come and join us. Most developers hang out there, so this is a great place to talk about the things you are tinkering with in Betaflight, or get help with really complicated configuration problems.

Alternatively, if you don't use Discord and you want to talk about Betaflight, ask configuration questions, or just hang out with fellow pilots, you can do this in our Facebook group.

Betaflight 4.4.0-RC4 brings the following updates:

Betaflight 4.3.0

Introducing the much anticipated and patiently waited for: Betaflight 4.3.

IMPORTANT: Make sure you install and use the latest version of the Betaflight Configurator (10.8 or higher) from https://github.com/betaflight/betaflight-configurator/releases/tag/10.8.0 before updating your firmware.

Please read these important introductory notes:

  1. After updating to Betaflight 4.3, you MUST use the latest 10.8 Betaflight Configurator. Earlier 10.8 and 10.7 configurator versions will not work properly with 4.3.

  2. F4 processors should run a 4k PID loop. F411 users should use DShot300, not DShot600, and are blocked from an 8k PID loop. Most F411's should be overclocked to 120Mhz, though some will only tolerate 108Mhz.

  3. 4.3 has a new Slider tuning approach and Presets. Due to parameter changes, do not paste in CLI ‘diff’ or ‘dumps’ from previous versions. A suitable Preset should give great results. The Sliders simplify making final 'tweaks' to your tune.

  4. Experienced users who want to use numeric data entry for tuning and filters MUST first disable their sliders. It's easiest to do that in Configurator.

  5. Check all your settings carefully before arming for the first time. Check PIDs, Filters, Rates, motor configuration and motor rotation. For the first flights, arm in a safe place, fly gently, and look out for any setup or build issues.

  6. We recommend using RPM based filtering for best performance**. Read about enabling and configuring rpm filtering
    here.

  7. 250hz or 500hz radio link users MUST choose a suitable Preset. 500hz radio links must have feedforward_smoothing set to 65-70 with 2 point averaging. 250hz radio links need feedforward_smoothing set to 35-40 with 2 point averaging.

  8. CPU Usage is now reported as a much higher value than previously. This is OK, it's just a change to how we display it. Don't be concerned until it gets around 75%.

For more details and to get the best out of the flight performance improvements, please read the Tuning Notes.

If you want to talk about Betaflight, ask configuration questions, or just hang out with fellow pilots, you can do this in our Facebook group.

Betaflight also has a presence on the Discord messaging platform. Come and join us. Most developers hang out there, so this is a great place to talk about the things you are tinkering with in Betaflight, or get help with really complicated configuration problems.

Betaflight 4.3.0 Release Candidate 7 Pre-release
Pre-release

This is our seventh release candidate (RC7) for Betaflight 4.3.

This release candidate is likely to be the final release candidate before we do a final, and move to start working on 4.4. We anticipate that the final release will be in approximately 7 days (if no major issues are discovered).

Remember some things may need fixing and fine tuning, and there may still be bugs. Please use it with caution and report back any issues at https://github.com/betaflight/betaflight/issues. Thank you!

**Note: Failsafe code has been updated extensively. See: https://github.com/betaflight/betaflight/blob/master/docs/Failsafe.md

**Note: The Betaflight side of CRSF baud rate negotiation has been improved, but it will require new RX firmware to be released for best results. If you're experiencing issues, crsf_use_negotiated_baud should be kept OFF(default) until further notice.

IMPORTANT: Make sure you install and use the latest version of the Betaflight Configurator (10.8-RC7 or higher) from https://github.com/betaflight/betaflight-configurator/releases/tag/10.8.0-RC7 before updating your firmware.
