What it does

  • Opens Blackbox flight logs in a web browser and lets you seek through them to inspect graphed values at each timestep.
  • Can load a flight video and play it behind the log, synced by aligning the log start to the arming beep.
  • Lets you customize which fields are plotted, such as separate gyro plots per axis or battery voltage against throttle.
  • Can export the graphs as a WebM video to share with others.
  • Built as a progressive web app so it can run online or be installed for offline use.
  • Now built into the Betaflight App as the Blackbox Viewer tab; this repository receives no further development and will be archived.
