Sure, simple :)
Brian, can I have your opinion on how much the overall system efficiency would change going from a 1000 watt setup on 3s to a 1000 watt setup on 6s, using a MMP 1512 type combo, adjusting kv for max motor efficiency. Also dropping the Mah of the battery in half.
Ha ha, crazy, I'm running one of those Quark 80's now. I have it in a Slash 2x with Jato arms. I run it with a Tacon 3930kv 3650 motor on a 2s 6000mah. Temps will normally be around 30-40 above ambient. This is a graph of it running 40mph, with Badland 30 series. I kill the battery in around 20 minutes. It's probably pretty close to the same weight as the above Pede.
So here's what I don't get, I'm running 20 minutes on 6000mah going 40mph, you say

I could run 60+ minutes running a 4s 3700 mah 20C flightpower lipo. Not sure exactly what the gearing was, but it did 45 on radar runs with masher 2k tires. Temps always at around air temps

So according to this claim, if I was to run the same time , even at my lower speed, I would need 3 packs , or 18000mah on 2s the equivilant to a 9000mah 4s, or around 2.5 times more battery.
These are the kind of claims that confuse me. I just can't see where that kind of difference can really be had. I could see maybe the extra 5mph coming from the added efficiency of the voltage, but 5 mph and 2.5 times the runtime....
