Those 108A peaks made me suspicious and led me to believe you are using a 100A version. My old burned up 100A version recorded similar peaks and also maxed out at 120A. I am now using a 150A version and the graph depicted in the turnigy thread was recorded with the 150A version.

Wow, what happened exactly this early into this run? Did your MMM fail from one moment to the other (as a result of something - braking?) and shorted the batteries. Lipo batteries, Receiver and servo alright? That's an interesting log for sure.

Side note about braking:
When zooming into a graph you might be able to see voltage rise although amps rise too. This happens when you brake with your ESC and current flows back to the battery. The eagletree logger records positive amps although you are not drawing current from the battery.
