I've got some polyquest 4500 45/90C packs on the way. It happens with or without the eagle tree. The same batteries are fine in the mbx though. I've got my mmpro/1512 1800kv in the mp9 and ready for testing to eliminate the car as the source.
Here's the worst example of the glitching I have found. I don't know enough about FET switching and how the RPM sensor works to know if it really indicates a problem with the ESC. It might just be what cogging looks like. I got a little more run-time on this one but it still only used about 2300 mAh.
