My A123 cells are dying... help?

[wulfgang]

I have not found the perfect outrunner for this application, so if you find an outrunner than can do the duty on 4S, I'd be happy to hear about it. Mine is 600 kv, and so by the numbers it *should* be great. But it's not. Plus, 6S A123 packs are quite heavy for a 1/8 buggy. So I need kv = 800 or so for 4S, and motors that size are hard to find.

Another option is to get a Turnigy 50-65 400 kv motor (fits my mount and has the 8 mm shaft) and re-wind it to 800 kv. Stall torque is independent of turns, so even without a re-wind, that motor should accelerate well with a possibly limited top-end.
