FPVTune is a Betaflight blackbox analysis and PID tuning assistant for FPV pilots who want better flight feel without spending every weekend guessing at sliders. Instead of asking a pilot to manually interpret gyro traces, noise peaks, D-term behavior, prop wash symptoms, and thermal risk from several different tools, FPVTune turns a recorded Blackbox log into practical tuning guidance that can be copied into Betaflight Configurator.
The workflow is built for real freestyle, racing, cinematic, and whoop pilots. A pilot records a short flight with Blackbox enabled, uploads the .BBL or .BFL file, adds the current CLI dump, and receives suggested PID, filter, and feedforward changes based on the behavior shown in the log. The goal is not to replace pilot judgment or safe test flights. The goal is to give pilots a stronger starting point than stock presets, copied YouTube tunes, or random trial and error.
FPVTune looks at the signals that usually matter when a quad feels rough: gyro noise bands, resonance frequencies, oscillation patterns, prop wash recovery, D gain limits, filtering delay, and motor heat risk. It is especially useful after a rebuild, firmware update, frame change, motor or prop swap, or any situation where the old tune no longer feels right. The output is written in the language FPV pilots already use, including Betaflight CLI-style recommendations and plain explanations of what changed.
This project is also meant to make Blackbox data more approachable for newer pilots. Tools like Blackbox Explorer and PIDToolbox are powerful, but they assume the pilot already knows what to look for. FPVTune bridges that gap by highlighting what the data suggests and why a change may help. More experienced pilots can still use it as a second opinion before doing manual fine tuning.
The product is web-based, fast to try, and designed around the normal Betaflight tuning loop: fly a clean test pack, review the log, apply a conservative change, and test again. FPVTune focuses on safer, incremental recommendations rather than aggressive one-click magic. It works best when pilots provide good logs from controlled flights, and it encourages users to verify results in the air rather than blindly chasing numbers.
FPVTune is useful for FPV pilots, drone builders, racers, freestyle pilots, and anyone maintaining Betaflight quads who wants a clearer way to move from noisy Blackbox data to practical PID and filter settings. It is a small, focused tool for a very specific pain point: making Betaflight tuning less mysterious and less time-consuming while keeping the pilot in control.
