Betaflight Autotune: It exists, but don't trust it yet

Betaflight now has an autotune tool in the 2026 master branch, which is basically the coding equivalent of 'hold my beer'. It promises to solve all your PID problems by magically analyzing your blackbox data. What it actually does right now is generate some truly magnificent graphs while its ability to recommend and apply actual PID settings is slightly more questionable. It might work, or it might set your pitch gains to zero and ruin your day. It’s not magic; it's math that hasn't quite grown up yet.

Using it involves flashing unstable firmware with chirp enabled, sacrificing a switch to Chirp mode, and setting Blackbox logging to debug chirp. Don't worry, skipping any of this will result in beautifully formatted, utterly useless data. The actual test flight is mercifully short and boring – a few throttle ramps and some automated wiggles (chirps) – which is probably the safest part of the entire process.

For experienced pilots who actually understand Betaflight tuning, the spectrograms and step-response graphs are genuinely excellent analytical tools. For everyone else looking for that one-button miracle, please don’t click 'Apply'. At least, not unless you enjoy rebuilding quads and want to help Betaflight collect 'evidence gaps' by crash-testing their algorithms.
