FPVTune

FPVtune is a neural network-powered Betaflight PID tuning tool for FPV pilots. It takes blackbox logs from Betaflight and analyzes them to generate optimized PID values, filter settings, and feedforward gains in seconds. The product is aimed at pilots who want a faster way to tune drones without spending hours on test flights and manual log analysis.

The workflow starts by uploading a .BBL or .BFL blackbox log recorded in Betaflight Configurator. FPVtune then performs spectral analysis on gyro data, identifies noise frequencies, measures step response, and compares the current tune against reference logs. Based on that analysis, it returns suggested settings that can be copied into Betaflight Configurator using generated CLI commands.

The site says the tool is compatible with Betaflight 4.5 and newer log formats. It also presents separate tools for crash analysis and motor health checks, along with tutorials and a blog for learning more about PID tuning. FPVtune describes its tuning approach as useful across different drone sizes and flying styles, including tiny whoops, 5-inch freestyle and racing quads, 7-inch long-range builds, and 10-inch cinelifters and X-class drones.

In addition to tuning, the product highlights analysis around gyro noise, dynamic filters, and motor thermal prediction. It also mentions support for common ESC protocols and gyro chips, and says the generated settings are designed with safe ranges for the aircraft in mind.
