Guys When testing the HW80A with a different timing, it failed.

Prior to failure, I was getting a peak of 93.43A at 4S at 7.5 degree timing vs 127A peak at 3.75 degree timing.

I was running the truck without any problem at 3.75 degree. And upon changing the timing, I could feel that the acceleration was significantly reduced, top speed reduced and motor/esc temp reduced. The ESC failed after several speed passes. While doing the last speed run, the truck slowed down to a crawl for no reason. It still moves but very slow. I had no accident with the truck. I was simply doing speed runs. The ESC did not overheat. Temp should be around 50 C. I've measured the esc at 53degrees before but this time, it feels cooler and so I estimate it to be around 50C at the time of failure. I didn't know what happened to my truck. The motor seems to be alrite and so I opened the esc to take a look.

Several of the mosfets are cracked or exploded as seen in the pictures. Broken particles from the mosfets can be seen on the PCB. Now I need to get a replacement. Damn. This is only the 2nd week of owning the ESC. Now I am afraid to get these HW escs. To the ppl here, don't play around with the timing.
