ESC in flames - 09.12.2009, 11:17 AM

sorry, no pics...

I took my LST XXL out for a first run today, and it ended with the esc going up in flames. It's an airplane esc with car software, scorpion 12s130a.

My setup:
Neu 1521 1.5y
NEU Energy 4s&5s 3300mah30c
12s130amp scorpion esc
Geared 24/63 (35mph without ballooning)
LVC was set at 29v, 3.22v/cell

Eagle tree data showed peaks of around 90 amps, until the end, where there was a 180amp spike. I had the eagle tree connected to the 4s lipo, and at that point voltage dropped to 9.9v.

The 5s pack was new, and the 4s pack already had a few runs on it. I've connected the lipo's to my charger and they seem fine. I've attached the eagle tree data of the run, and a highlight of the end of the run.

What killed the esc? And any idea what could have caused that 180amp spike?
