Well, like I said..... I run a 3 cell lipo down completely (well, I don't destroy the thing) from a fresh charge and I haven't had any problems with that. (yet) I've been running it for a while now. I only lost a 4in1 when I tried to run 2 fully charged packs back to back.

My motors are fine. My 4in1 in the CX1 is fine. I have no plans to use a 2 cell again. If I can find time (and help) I'll make a video sometime.
