Advice Needed - ESC went up in smoke unexpectedly!!

Hello! I'm working on creating a hexacopter that is larger than anything I've ever worked on before and I fear there is something fundamentally wrong with the electrical part of my build - an area I've always had problems with.

Before starting, here are my specs:

  • Tarot T960 Hexa-Copter

  • 3DR Pixhawk

  • Multistar High Capacity 6S 8000mAh Multi-Rotor Lipo Pack (x3)

  • 50A BlueSeries Brushless Speed Controller (x6)

  • 5008-340KV Turnigy Multistar Multi-Rotor Motor (x6)

I have each of the 3 batteries split to power 2 esc's each. I went to calibrate one of the esc's individually, so I had my pixhawk connected to Mission Planner, my transmitter on and throttle set to high, and then I plugged in the esc directly to the battery and it immediately went up in smoke (!!).

I have done a successful all at once calibration before and I had the esc's up and spinning - responding to motors fine. The individual esc I was trying to calibrate was because I was replacing just one individual esc. I have never even gotten to the point of putting propellers on, let alone flying. I am really not sure why my ESC blew and am afraid of trying another one.

Could anyone provide me some guidance? Or ask me some more leading questions that could help me figure it out?

Thank you so much - I really really appreciate any help!

  • You may have a short that caused the ESC to burn ! Please check make sure yo do not have any exposed wire or wire touching Carbon fiber! the other is you may have bad ESC batch.
