Today, I experienced a troubling incident involving my X8 quadcopter, which is equipped with a Cube Orange Plus flight controller running ArduPilot 4.5.1. The drone is powered by two 16,000 mAh batteries. While disconnecting the batteries, the motors unexpectedly spun up to a high RPM, causing significant injuries to my hand.
What makes this situation particularly puzzling is that the drone was not in a state to be armed at the time, ruling out the possibility of the motors being triggered by an RC input. Additionally, there are no log files available to analyze the event since the Pixhawk only begins recording logs once the drone is armed. This lack of data makes it difficult to diagnose the exact cause of the incident.
