I've always used Lighter fluid to take sharpie marks off, perhaps it'll work on the paint as well?

where is PA's new raceway located? address?

Thanks

Zip is right, her name is Heather and I think her controllers were called "Controllers by Heather". She is no longer doing anything with slots last I heard.

Way to go Bernie!!!

try Camen www.camen.com

On the one that failed, were you using a heat sink?


thanks

Don, why reinvent the wheel? a standard relay will work fine for your purpose at 1/3 or less the cost AND not require your expertise should a problem arise....just a thought.

Don, for he uses you describe, a standard automotive "Cube" type relay would be fine. the link provided has a 40 amp available at reasonable price. You could even make up a system where they are...

Cheater, You are incorrect,the USRA was in fact at one time Incorporated for one or maybe two years but it wasn't continued. not sure what the the time frame was at the moment and not really...

If you use Priceline, choose "Express Deals", then "Gaithersburg" you can find up to a 3 star for around $60.00 per night.

If you build it...they will come........Good luck with it Marlon.

Guys, I think the commentary isn't really needed. This is a schedule announcement for the USRA Nats, not an open invitation to bash the USRA. it's not fair to Frank nor the organization, please...

Magnet wire has a insulating coating on it so any measurement you make without removing the coating is suspect and inaccurate.

Eric, only one raceway bid for next year and they of course got the Nats, Frank Sarkela's place north of Frisco.

Closely matched magnets will not be once the motor is installed in the car, the affect of the steel axle and motor brace will increase the Gauss of the rear magnet. Try it yourself with your Gauss...

One thing to keep in mind when doing your tests is track condition. A properly prepared Spray Glued racing surface is far different than a surface typically found on a track on non racing days. Also...

Over the years it seems that it's been customary for the USRA to put out a reminder prior to the deadline, did I miss it somewhere this year?

Mike, can you point me to a place where those rules are written? I'm curious.

I've used my capacitor zapper when I ran ceramic stuff and it typically exceed what my coil based zapper would do.

Though a proper device for measuring and mapping a magnets field would set you back a substantial amount of money, the attached has some items, reasonably priced, that would give you some way to see...

Robert, not sure I got my point across.

C can arms have not gotten smaller, they've gotten bigger if anything. Typical c can mags are designed (thickness) to accommodate a typical .513 or .518...

C can mags are/were typically designed for much larger arms than are being run in I-15 so even if you cut them down to fit you'll still have to shim them up to get a decent air gap.

There was a...

It's essentially an "Open" motor but a very mild one. Probably built to be used in some sort of Eurosport car or perhaps F-1 because of how mild it appears to be.

I agree with zipperi, looks like Camen hardware and also Camen can/endbell (very old) arm looks like maybe Proslot P/S and wind maybe 45/29

Last year I was the race director for this race and the year before I was a participant...in neither of the two races do I recall anything about someone changing to smaller tires being an issue of...
