how do you figure out how many amps?

[ReV:-O]

loads of people run 6s on the 1515/1.5D, which puts them right around 60,000RPM and run with generally no problem. i think its best if you gear for 40,000RPM and then hav no problem whatsoever...

eh, not too bash, but its a silly setup. One of them has killed a few more electronic bits than that on past setups, and as far as I can tell its just running spd runs up and down the street. Put it on the track or bash it hard offroad (like hill climbs and such) and you are going to see lava. Whatever, to each his own, but I have been seeing alot of "why is my Neu 200F?" or "why are my lipos melting?" threads lately w/ these setups. If you want so much power, go higher voltage.


On topic:

Anymore I have a good idea of the power of the system. If its a ~10 lb MT or 1/8th scale, if you are pulling 45mph, you are prolly around 1600W. 50 mph=2000W, and 40 mph=~12-1400W. Then just divide the watts by # of cells*3.5V (assuming decent batts)

That usually puts you in the ballpark of peak amp draw. More detail than that you need a ET.
