Very nice! Here is a link to a video from a different
viewpoint:

http://www.youtube.com/watch?v=o7no9ZwKHzU

You can see Derek by the water box.

I don't know what YouTube does with the information,
but when you upload a video, you can use a GoogleEarth
type feature to pinpoint the location where the video
was taken. You can see a satellite view of the
location you are selecting. It's amazing, I was able
to select that the bike was in the right lane, and
even determine the difference between the water box
and the starting line, by the two tire tracks!

While patting your selves on the back for such a great
burnout, I was wondering isn't sort of a bad thing?
After all the intention is to warm up the tire to get
a great stick to get great times. With so much smoking
the officials have to wait to be able to see the and
in the time the smoke clears your tire might start to
cool off. Just a question and observation from a
non-racing peanut gallery.
And another question. Hows the brush shifting working
out? Sounds like it is keeping the comm and the motors
from burning up on you at least from reading all your
post.

At some point in time, will it be set to the full 2,000 amps?

What motor voltage is it running/will it run?

Hey Bruce, all

I feel it's been a nice breaking ground on variable
brush advance. Usually just jiggling a brush can
cause it to chatter a bit until it seats back in so
I've been pleased to see it working so well.

I believe it'll be just a matter of timing thier
shifts just right, having great track conditions,
maybe a little more tailwind and they'll crack into
the 7's 8^P

Have you considered using any sort of "chain wax" instead? What are
you currently using? Also, which chain do you use?

How about some "Burnout Guard"?

Anything you can share so I can get on the same page as to what's on the board?

Burnouts are sometimes misunderstood. There are actually more reasons
to do this than to get the tire warm. Racing tires have a softer
compound than street tires. As you are riding through the pits you
pickup small rocks and lots of dirt on the tire. You want to remove
this before you run or traction will be lost and this not good. You
also want to heat up the tire to make it stickier than normal. With a
new tire like the one in the video the first run requires a longer
burnout. This is because as it comes out of the mold it is smooth and
not as sticky and also has tiny rubber barbs sticking out of the tire.
So you have to scuff away a layer to get to the softer compound. This
requires a longer burnout.

The tire does start to cool off slowly as it is rolling up to the
tree. But the A123 cells like the delay before launching. The
chemistry has been excited by the burnout then the delay lets the
chemistry recombine.

The brush timing is working great. It lets us run harder and still no
problems with the motors. In fact there is no noticable discoloration
of the copper going to the brushes. Still bright and shinny inside.

Did they get the history of the naming of the Killacycle correct?

Since it is a DC machine I would think it came more from kilowatts than
kilohertz

(although, the controller does use 15khz PWM.....hummm)

Also, new tires top layer of rubber is not as good as the fresh rubber
underneath. They use a mold release agent and it gets into the surface.
The rubber also dries out and looses some of it's properties.

In road racing and autocross, smoking all for tires is not possible, so
they put them up on a lathe and cut off the layer of
old/oxidised/new_contaminated rubber before important races (also on DOT
rubber to shorten the tread height making it last longer)
