Hi,

Rick, the problem with Pre-'70, or pre-'68 (better) is that even P doesn't know all the stuff that was run.

Remember that '66 era 26D/Pittcan "Midwest" style inline I run a lot for fun with the Lotus body? Du-Bro bracket, inline, piano wire rails, no drop arm, both pans linked together and "floating" in all directions. What we called, then, a rattlepan.

I think that the first time P drove it 7 or 8 years ago; he had not seen that set up before. When I did a similar chassis with the FK, a friend objected that its rattling in all directions was too much movement for DIII and I didn't run it.

I do not know it all.

Stupid question, but I gotta ask because I'm totally new to scratchbuilding and retro racing.

Maximum body height is 1.375", and a half-inch spoiler is allowed above that. If the actual body height is below the maximum, can the spoiler be a little longer to make up the difference, or would this be an improper use of air control devices?

Or, second stupid question, am I reading the rules wrong?

Hi,

Part of our friendship, Philippe's and mine, is one of us has a bit to show and the other goes "really, I have NEVER...".

The hobby was so big back then. But now, part of the fun is talking to old racers one would have never been able to keep touch with using the technology of the times. And SEEING new stuff.

Richard,

Thanks for the clarification. The chassis Paul Sterrett originally used was something built for a vintage event a few years earlier. Since then he has built chassis closer to the basic intent of the retro racing idea.

Will the IRRA be formulating rules for 1/32 scale retro racing or will it remain strictly a 1/24 scale organization?

[Mike Patterson]

I have a question concerning the Pro Slot Euro motors. If I run one with a Chinese arm, and it pukes, can I have the motor rebuilt with an American arm? Conversely, can I upgrade to an American arm at any time, as long as the work is performed by a IRRA approved rebuilder?

That is a good question. What would Retro 1/32 rules require? What kind of cars would we be copying? Which historical era of 1/32 racing?

My vote is old motors, or current era equivalents, 1965-ish. 1.5 ohm minimum armature resistance. No Neo replacement magnets in open-frame motors. Any commutator and endbell, to avoid blowups and melts, and to allow can motors to be built up with some available parts, like Parma. Brass chassis, but current era silicone/urethane/rubber tires. Tracks would be required to have minimal scenery. For rules on bodies, see the Vintage Race Across America rules on SCI.

Ooops, I'm dreaming again.

Mike, I'm pretty sure the answer is "Yes", at least I hope it is yes because that is what I did and I helped make the rules for the IRRA. But it must be done by an approved rebuilder and have a seal on it.

[Joe Mig]

I hope this is a good place to ask this question.
How come you don't state anything about the payout at the end of the race?
Is there a payout or coupon, or is it all about bragging rights?

[Ron Hershman]

NO payouts... bragging rights and just having fun.

[Hworth08]

We never used to worry about the payout, didn't know where we'd finish.

But how much is the appearance money?

[Pappy]

You will be paid what you are worth. Bring plenty of money.

Having it done through the approved rebuilder would be fine, as it would be sealed.

No thoughts yet at all as there are other 1/24 classes to be considered first.

[Bill from NH]

Okay, I can create my own.

[gascarnut]

Just be sure to publish them - there are a lot of us who like to build 1/32 cars, too!

[Bill from NH]

Dennis,

I will in time, but I'm not looking for IRRA sanctioning. At the moment, this project has very low priority with me. I'll probably use the rules of our defunct 1/32 AMCA group for the basic footprint. We ran both sports car and F1/Indy classes.

Actually, I might build a couple cars and then write the rules.

[Mike Patterson]

I have another Pro Slot motor question: Is it legal for me to cut off the unused motor shaft on the endbell side of the motor, or do I have to let Ron do this?

[vfr750]

Hi Bill,

You might like to look at the rules we use for retro racing in the UK:

Mike,

There's no rule against you cutting off the shaft. Knock yourself out.

It can be cut off.

[Dominator]

Does the maximum width, 3.125", include body pins?

[IRRA Retro Racing]

Q: Does the maximum width, 3.125", include body pins?

A: The maximum widths in all classes are exclusive of body pins, body armor, or tape.

I have a question: How come there is no mention of a concours award and/or competition in the rules? I also noticed no mention of finishing position points. Is this detail going to be determined by whatever series is using these rules?
