# FAQ / [How-to] Bare minimum tune Betaflight ### Testing hovering tunes - Recommend test hovering tunes in short increments while checking motor heat. (10 second, 25s, 50s increments.) ### Try presets - Try them ## PID tuning ##### Recommended videos for tuning: (Brian White/PTB) - https://youtu.be/cUzNuMVxkBM - https://youtu.be/XxPBlMckeEg - https://youtu.be/NPS3aJqoFko ##### The idea is: - start with defaults - use sliders - turn off FeedForward (Stick response slider) - turn off D Min/Max (Dynamic Damping slider) - reduce i-term to 0.3 to 0.5 (Drift-Wobble slider) - find a good P/D balance (Dampening Slider) (PIDToolbox aka PTB) - ~~increase master multiplier as needed, but not excessive.~~ (this is potentially mis-information, but still works. see next item) - raise both P and D sliders in sync, and as as needed, for a more responsive overall system. (preferred rather than Master Multiplier as per @ctsnooze, a Betaflight developer) - return i-term but not excessive (sometimes 0.7 or 0.8 is fine; i don't see a need for more than 1.0 , but that's opinion) - revisit filter/PIDs as needed, but do not chase your tail, at some point there is diminishing returns. - enable FF as desired - maybe enable D/Min/Max again (i don't know enough about this, i know people use it, especially racers to keep motors cool, but my experience i prefer without because i tend to get weird jitters with it.) ### Or find presets that match your rig. ### Workflow 1. Always tune a quad with the same components you expect to fly. (HD Cam, prop-size, etc) 2. hardware first -- make sure everything firm and secure. no floppy wires, no floppy antennas, etc. no soft-mounting except the FC's gummies. 3. then tune filters, as per blackbox. - `set debug_mode = gyro_scaled`, `save` for anything useful. - how to perform blackbox: https://oscarliang.com/blackbox/ 4. then pids (without feedforward, without dmin/max for step-response analysis) 5. Repeat Filters and PIDs until no reasonable gains. ### Generally - Defaults are for 5 inch quads. - Smaller quads will need higher cutoffs (Hz) - larger quads will need lower cutoffs (Hz) - larger quads will need less i-term due to inherit authority of larger wingspan/propellers.
