betaflight release notesBetaflight 4.3.0 Release Candidate 1

[WaF Bot]

Just in time for Xmas...

This is a release candidate (RC1). It is intended for testing, and some things still need fixing and fine tuning. Please use it with caution and report back any issues at https://github.com/betaflight/betaflight/issues. Thank you.

Make sure you have got the latest version of Betaflight configurator installed before updating your firmware.

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 in the Slack messaging platform. Register here, and then come join us in Slack. 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 Release Candidate 1 brings the following updates:

Overall a smoother, more precise flight experience with better propwash perfomance 'and' also an easier setup and tuning experience - to release the full potential of Betaflight 4.

4.3 is a significant evolutionary step thanks to a slew of diligently coded and carefully tested updates representing thousands of hours of work from the voluntary development and test team.

• New PID based tuning sliders
• Presets
• The default PID and filter values have less gyro filtering and higher P and D, providing better 'out of the box' performance.
• We've changed how D is configured.
• More accurate loop times
• Multi dynamic notch
• The above two changes have significantly improved incoming 'gyro noise'.
• PT3 based RC smoothing
• RPM crossfading
• PT2 and PT3 lowpass filtering options
• Feedforward jitter reduction
• Other feedforward improvements
• AntiGravity improvements
• Dynamic gyro filter expo curve
• Improved dynamic idle
• Linear and Dynamic mixer options
• Feedforward in Level and Horizon Modes
• Actual Rates is the new Betaflight default
• CrossfireV3 and Ghost RC link improvements
• FrSky OSD fix
• Lua script updates
• Changed CLI command names - many CLI parameters are re-named.
