I just can't get enthused about the Flaming river switch... it's expensive
and it's mechanically actuated....

I know it's a real deal race car set up.... But... I would prefer to use to
master battery switches and the cable necessary to actuate them.... The
flaming river switch is about saving weight and shutting down mechanical
systems....it's lighter then the Power cables running around... weight
isn't an issue and shutting off a mechanical system isn't either...( I
don't have any ) So in my humble opinion it doesn't justify itself in it's
cost or mechanical complexity in my application. (KISS)

Wow now that was semi political...  I am very interested in putting a
switch on the back of the car that shuts down everything INSTANTLY...( not
just for the rules but for our personal safety)  and I would love to hear
more about these inertia switches...  that sounds like a really good
idea...
