A funny note about my hand. The left hand that suffered the worst burning in 
my little...umm...incident, have dark, sort of, copper colored areas on the 
thumb. I got curious and stuck the probes from my multimeter on them. With 
the dial turned to measure ohms, the dark patches measured only a few hundred 
ohms, while a patch of skin next to it measured 6 megaohms. Both patches of 
skin looked dry. Could it be that I copper plated my skin or impregnated it 
with tiny bits of copper? Just call me Borg!

On paper, it seems like the Raptors should be more than enough. In reality 
the contactor is much better, even though my batteries can only shove about 
700 amps through each motor.

I have to go clean-up incredibly thick soot off my box, components and 
controllers. I will post pictures of the Albrights this weekend. They look 
pathetic.
