Patrick, how about adding a brief not-too-techy note on your site explaining this? I've seen many many people who do not understand how much current these setups can pull (especially those guys who gear their E-Revo for 90mph and wonder why things blow). Maybe even some graphs for logged runs as proof of typical real-world setups? It would probably be good to note that some loggers can't measure the full current bursts because they are limited to their rating. Also, there seems to be a thought that since the ESC is rated for ~150A, that the ESC will only pull 150A whether you are gently driving a moderate setup or mashing the throttle on an aggressive setup. I guess what is needed is "layman's electronics 101".

Great idea - or how about a calculator similar to the ones you have Brian?
