Well, I'm using a 6-cell 5000mah with a full charge and my ESC LVC is set for 6 cells.

I don't think its pulsing as a cut-off warning....pulsing was probably the wrong word for me to use. The outrunner can is spinning in more of an abrupt, back and forth jerky sort of fashion. Its generating enough motion of some kind to swing the blades maybe one revolution every 4 seconds.

Right now the timing is set to auto...I'll try moving it to low (0-15) and then medium (5-20) and see if that helps. Should I be changing anything on the PWM switching? Right now its set to 8 KHz.
