Hello,
As I have two AQ-Boards now (one with DIMU, one with AIMU) that randomly freeze in mid flight (viewtopic.php?f=31&t=3086), I probably have to take the possibility of an influence of my setup into account.
The frame is a simple CFK-F8 equipped with 2212-Motors combined with the UltraESC. I had no issues so far using 3S batteries. But when I switch to 4S, I have random freezes. The AQ simply stops responding, no reboot and the status-LEDs simply keep there state. Often all motors simply stop at the same time and the copter comes down like a stone. It only happens with the motors running!
My question: Does anybody use the UltraESC with the AQ, mybe also with 4S? Is it possible that they create something in the PWM-lines that causes the AQ to crash?!?
