brushless and A123 questions

>I'm now running a 10S A123 pack w/ a 1100 kv motor and everything runs dead stone cold. :) Once you go HV you don't go back

@Finnster
Great to hear that your plan worked out. I really would be interested to see a new thread of your setup (with pics). btw welcome to to the 10s efficiency club

Yes, I agree, 5s2p would be the indeal way to go with A123 batts. A 6s1p will only get you 1080 watts roughly, you need more than that to give you the 'brushless grin'.

I run a 1512/3D on 7s1p A123 pack and I get up to 1500 watts from it, I get roughly 15 mins runtime, and I can charge it back up again in 25 mins. It's great. I also have a 7s2p pack I use mostly though. I am thinking about trying out some FlightPower 6s packs sometime.

Just for reference, each M1 cell can deliver a 'solid' 180 watts. When I say 'solid', I mean 'useful' power that can be drawn by an R/C power system.
