Flowshutter is a custom camera remote. When used in conjunction with readily available hardware, this results in a flexible and reliable external camera motion logger for Gyroflow. It can provide precise synchronization of camera video recording and motion logger (betaflight/emuflight FC) recording.

It was designed to be used with the Gyroflow software to provide you one of the best open source video stabilization experiences.


  • "1-click" - synchronously start/stop (1) FC arm (2) camera recording
  • "Audio injection" - inject sync marker to the audio track for precise synchronization between video and gyro data
  • OLED Display - show the device information and allow user to change settings without hacking the firmware code
  • Blackbox Erasion - erase all blackbox data without connecting to the computer
  • OTA Update - (WIP) update the firmware over the air
