FPVTune
Neural network Betaflight PID tuning from your blackbox logs
About FPVTune
PID tuning is the part of FPV drone building that separates people who fly well from people who fly what they built. Getting it right means reading blackbox logs, interpreting FFT plots, identifying resonance frequencies and understanding how filter changes interact with PID gains, which is genuinely specialist knowledge. Most pilots either copy someone else's tune for a different airframe and wonder why it flies badly, or accept the defaults. FPVTune applies a neural network to the log instead, identifying the noise characteristics and generating settings matched to the specific aircraft.
The analysis targets the things that actually determine a tune: gyro noise across the frequency spectrum, resonance frequencies specific to that frame and motor combination, and step response behaviour. Output includes safe ranges rather than only point values, which matters because a tune that is theoretically optimal and outside safe bounds for your setup is a crash waiting to happen. Two additional tools are free: a crash analyzer that diagnoses why a drone came down, covering ESC desync, power loss, failsafe, gyro overflow and lost props, and a motor health check. Compatibility is Betaflight 4.5 and later. Pricing runs from a single tune through subscription tiers with progressively better per-tune economics.
Fly your quad and record a blackbox log, then upload it. The neural network analyses the log, performing FFT and step response analysis to characterise gyro noise and identify resonance frequencies particular to your frame, motors and props. It returns optimised PID and filter settings along with safe ranges for your aircraft, so you know how far the recommendation can be pushed. Apply the settings in Betaflight and fly again. If something goes wrong, the free crash analyzer takes a log and diagnoses the cause among ESC desync, power loss, failsafe, gyro overflow or a lost prop, which is often faster than working it out from the wreckage.
- •Neural Network Log Analysis - Machine learning applied to blackbox data rather than fixed heuristic rules
- •Resonance Frequency Identification - Finds the frequencies specific to your frame and motor combination, which is what generic tunes cannot account for
- •Full FFT and Step Response Analysis - Precision analysis on paid tiers rather than a simplified pass
- •Safe Ranges Provided - Recommendations come with bounds, not just point values, so you know how far to push
- •Free Crash Analyzer - Diagnoses ESC desync, power loss, failsafe, gyro overflow and lost props from a log
- •Free Motor Health Check - Per-motor assessment, useful before a tune rather than after a failure
- •Betaflight 4.5+ Compatible - Targets the current firmware generation
- •PDF Reports and Tune History - Exportable reports and a record of past tunes on paid plans
For FPV pilots building their own quads who want a tune matched to their specific airframe rather than a setting copied from a video about a different one. It suits weekend pilots with one or two rigs, where the single-tune price is the sensible option, and multi-rig builders or squads who tune often enough for a subscription to pay for itself. The free crash analyzer is worth using regardless of whether you pay for tuning. Newer pilots get the most benefit, since this substitutes for expertise that otherwise takes a long time to acquire.
