So I thought I would post my eagle tree data from my short run before my MMM died. The Eagle Tree CDR file is attached. The graphs below show most of it. The second picture shows the biggest amp spike. The most concerning thing is the voltage drop. The pack is a brand new 4900mah 6s 20c neu energy pack with a MMM and Feigao 11XL 1516kv motor. You can see in the graph where the MMM died. It is doing what others have described, fan twitches when it is switched on and off, and castle link can't connect to it. Also the 65000 rpm spikes are just errors from the brushless motor rpm sensor.
