isnt the big one already out?
called the SHV-200??
up to 200A continuous with a bit of airflow over it.
i think one of these days i'm acutally gonna ring castle and see if they could make me a BIG ESC (500A) to put in a REAL car...i.e, my VW beetle.
i'd love that!!, then i'd have to go to poweriser.com and buy some of their 300AH lipos...or a LOT of A123 cells
such a cool project...and u'd get a re-bate from the govornment over here
