I use Arduino Nano in my quadcopter and after a few crashes it stopped working. I changed it to another arduino, had a few crashes and it stopped working again.
Arduino was never “touched” when my quad crashed, it was inside a protective case. The only way it could damage itself would be with the G force of the collision of the quad with the ground.
Looking carefully to my arduino nano board (both) nothing looks wrong, absolutelly nothing. I smelled all the board and it smells good, nothing burned.
When I connect both boards to USB of my comptuer, the PWR light lights on but no other LED works. My ARDUINO IDE also recognizes the arduino board (COM3) but when I click upload a SKETCH arduino hangs at UPLOADING… and nothing else happens.

Do you have any idea what piece/part could be dead in an arduino nano when it has really strong G forces acting in it? Do you have any idea what should I try to fix, remove or replce in my board?
