What is PID tuning on an FPV drone?

PID tuning adjusts how your flight controller corrects the quad’s attitude. P reacts to current error, I holds against steady drift, and D damps overshoot. Good PID values make a quad feel locked-in and precise instead of mushy or oscillating.

Do I need a blackbox log to tune PID?

Not strictly, but it is the difference between guessing and knowing. A blackbox log records gyro, motor, and PID data from a real flight so changes can be based on evidence — step response, noise spectra, and motor balance — rather than feel alone.

How do I fix propwash with tuning?

Propwash oscillation usually points to D-term and filtering that cannot keep up. The fix is data-driven: check the blackbox for the oscillation frequency, then adjust D, D-min, and filters together rather than chasing one value.

FPV Drone PID Tuning Guide: From Blackbox Log to Locked-In Quad

How an FPV drone feels in the air comes down almost entirely to whether its PID and filters are dialed in. This guide connects the whole path: what PID and filters actually do, how to read problems out of your blackbox log, and how to fix the most common issues — propwash, hot motors, and oscillation. New to it? Start with PID tuning basics.

What PID actually tunes

Thousands of times per second the flight controller compares your stick command against the gyro’s measured attitude and corrects the error with three terms:

P (Proportional) — the immediate reaction to current error; sets how sharp and connected the quad feels.
I (Integral) — holds against steady drift (wind, CG, thrust asymmetry) so the quad bites and stays on attitude.
D (Derivative) — damps overshoot and oscillation; central to propwash, but too much amplifies noise.

Why blackbox data beats guessing

Feel tells you something is wrong but not why. A blackbox log records gyro, motor output, and PID error from a real flight so you can see oscillation frequency, noise spectra, and motor balance — and base changes on evidence. To get a log, see how to export your blackbox and export a CLI dump.

Filters and noise

Filtering decides how much D you can run before motor noise gets amplified. Your gyro/D-term filters and bidirectional DShot RPM filtering directly affect motor temperature and feel. To understand what each filter does, read filter settings explained.

Common problems and fixes

Propwash oscillation — D-term and filtering can’t keep up; tune them together to the oscillation frequency.
Hot motors — usually noise reaching the D-term; tighten filtering and D.

Tuning by aircraft and style

A 5-inch freestyle quad, a racer, and a tiny whoop want very different tunes. See freestyle vs racing tuning, the racing guide, and a small-frame example in Air65 tune presets.

Tune by hand, or let a tool read it for you

You can read the graphs and tune manually, or let FPVTune analyze the log automatically and hand you PID and filter settings directly. For the trade-offs, see FPVTune vs PID Toolbox. When you’re ready, upload a log and start tuning.
