My quadcopter suddenly fall down after 50 seconds.
Before the fall I flew 3 minutes successfully at Alt Hold mode.
After crash I measured battery and it showed 23.74V but at flight log CURRENT:Volt value is 21.71Volt at last log row. Before the flight battery module was calibrated.
Thanks for any help.
