Thruster t200 of rov2 automatically run when I press armed

sir/mam , when everything is connected ,and turn on armed mode all left side thruster started automatically.

Hi @rinku,

  1. Which flight mode is your vehicle in (e.g. manual mode, or one of the controlled modes)?
  2. Is this a standard BlueROV2
    • running ArduSub firmware and
    • using our BasicESCs?
  3. Does the problem persist if you reset parameters and recalibrate your sensors?
