My quad, with a version of Copter 3.4.5 on its Pixhawk, crashed while flying in LOITER mode. The logs show that the logging stopped mid-air without any apparent errors or erroneous data. I suspected a faulty power module or harness that cut off power but the components turned out to be functioning fine upon testing. Even the Pixhawk is powering up and sending data properly and is even logging data. I’ve run out of ideas about what else could have gone wrong so if anyone has any other ideas, it would be very helpful.
