New Hobbyking 40A blueseries ESC burn out!!

I am new to the field of Drones,and would like to learn about it.

I built an H quad using hobbyking 40A blue series ESC, 800KV sunnysky outrunner,  and 16000mAH LiPo battery pack.

I am using Pixhawk as my flight controller.

While  doing the throttle calibration of ESC, an esc was not beeping, and after some time got burnt with smoke. I have attached the photo of the burnt out ESC(top right part of ESC burnt out).

Please help me to find the solution!!

  • blown cap! Maybe wrong polarity?

    • No, I checked the connections,not wrong polarity.

      couldn't identify the component which blew(below capacitors)!!

"Wow, Ning2 looks really great on mobile. I had sort of drifted away as my browse-time went more on my phone, so this is great."
