Recently, my Octoquad while in flight has a situation where the propeller jammed up with a skid that came loose causing the ESC to burn up and seriously damaged the UAC arm and wiring as well. Is there a feature in Arducopter to allow the MCU to sense a spike in power for any ESC and allow it to be shutdown due to a serious anomaly?
I have 3D printers that use a similar technique to sense when the extruder has hit a stopping point whether is it the frame (called sensorless homing feature) or a printed object thus stopping the movement and saving the printer from damage.
