Hello, I have just assembled and test flown an Xaircraft X650v8 with Wookong-m and AKE 12 amp high-speed ESCs. I am running v5.14a firmware. Everything is working great and the vehicle hovers fine in ATT and GPS mode. However, when I command a "pulse" in yaw (or throttle) while in hover, motor # 2 quits (stops turning). This is consistent and repeatable while flying in ATT mode (and in GPS mode). When the motor stops turning, the LED goes from blinking yellow to blinking yellow/white (indicating attitude status fair or bad). If I land, shut motors down and rearm, the motor works again and quad flies fine until I induce another "pulse" in throttle. Note that the actual yaw/throttle "pulsing" is induced by me, not the vehicle. And it always motor #2 shutting down.

I have replaced the ESC and motor with new ones & tried older 5.12a firmware ; same problem.

any ideas?

Verify the correct programming of the ESC associated with that motor.

It's now typical to program the ESC's for Nicd/Nimh instead of Li-po to prevent low voltage shut downs.

Chris, thanks. I will try that. is it really possible that some ESCs have one setting and other have different? I have 8 of them total.
