bbdoctor — what is wrong with your drone?
bbdoctor is an online service that analyzes blackbox logs recorded by Betaflight flight controllers and explains, in plain words, what is wrong with an FPV drone and how to fix it.
What it finds
- Which motor or propeller vibrates (imbalance, bent prop or bell) — per motor, using RPM telemetry
- Worn or slow motors (lower RPM at the same command)
- Center of gravity offset, tilted motor, frame and stack resonance
- Gyro noise, motor heating risk, filter delay
- PID overshoot (step response), propwash after throttle chops
- Battery sag and internal resistance, crashes, failsafe
The result is an online report with charts and ready-to-paste Betaflight CLI commands. The report is delivered instantly after the analysis (digital service, no shipping).
Pricing
The service is free (at most 30 analyses per hour from one address).
