Betaflight tuning guides
Plain-English guides to PID tuning, filters, blackbox logs and what changed between firmware versions.
Betaflight Autotune in 2026.6: how it works and how it compares
How Betaflight's experimental Autotune tab works, what the chirp test measures, what it can and can't change, and how it compares with tuning from a normal test flight.
Betaflight PID and filter tuning: the 2026 guide
The order that works for tuning a Betaflight quad, filters first, then P and D, then feedforward and I-term, with what to measure and the defaults for 4.3 to 2026.6.
Feedforward, I-term relax, anti-gravity and TPA explained
What each Betaflight setting does, its CLI names and defaults by version, the symptom that points to it and which way to change it.
PIDtoolbox alternatives for Betaflight blackbox analysis
What PIDtoolbox shows, the tools that do the same job in 2026, and the difference between tools that draw graphs and tools that choose the values for you.
How to read a step response in Blackbox
What a step response plot shows, how to read overshoot, rise time and settling time, and what the shapes say about P, D, I-term and feedforward.
How to tune a Betaflight quad by size: whoop to 7 inch
How Betaflight tuning priorities change from 65 mm whoops and toothpicks to cinewhoops, 5 inch freestyle and race, and 7 inch long range. Direction, not magic numbers.
What changed for tuning in Betaflight 2025.12 and 2026.6
The D-term rename that swaps base and peak D, new feedforward defaults, the 2026.6 D max and gyro changes, and what to check before pasting an old diff.
Betaflight filter tuning: gyro, D-term and dynamic notch settings
What each Betaflight filter does, the default cutoffs by version, how to read a throttle-sweep spectrum, and a safe order for changing filters.
Betaflight sliders explained: simplified tuning and the master multiplier
What each Betaflight PID and filter slider changes, the CLI names and defaults, how sliders turn into PID numbers, a safe order to move them, and when to use raw PIDs.
How to fix propwash in Betaflight
What propwash oscillation looks like in the air and in a blackbox log, why filters don't fix it, and the order of changes that reduce it in Betaflight.
Betaflight tuning glossary: PID, filter and blackbox terms
Plain-English definitions of 26 Betaflight tuning terms, from P, I, D and feedforward to RPM filter, propwash and blackbox, with CLI names and links to the deeper guides.
Motors hot after tuning in Betaflight: causes and fixes
Why Betaflight motors run hot after tuning, how to tell warm from hot, and what to change in order: D-term filtering or D first, then gyro filtering.
RPM filter setup in Betaflight: bidirectional DShot and motor poles
How to set up the Betaflight RPM filter: bidirectional DShot, motor poles, the CLI defaults, how to check it works, and the mistakes to avoid.
Betaflight tuning tools compared (2026)
Blackbox Explorer, PIDtoolbox, Betaflight Autotune, FPVPIDlab, FPVtune and FPV PID Tune side by side, covering what each measures, what it changes, safety and price.
How to set up blackbox logging for tuning
What a Betaflight blackbox log needs before you can tune from it, the right logging rate and debug mode for each firmware version, and how to fly the test pack.
