Are my eyes or my brain going bad? Can Am rules here:

 

http://www.retroslot...com/can-am.html

Motor- The only allowed motor for Can Am is the
Sealed Pro Slot PS-4002-FK motor. All motors must run an 8 tooth pinion.

 

Then I scroll down to "Gears":

 

Gears-  Must use 7 tooth pinion only

Im fairly certain that also in the rules is a statement stating that spec pinion can be either 7 or 8 depending on the track being raced on.

 Correct. Under "General Rules" it says:

 

"All motors must run an 8 tooth pinion. At some events smaller pinion may be allowed due to track length"

 

But that doesn't change the fact the Can Am rules are ambiguous. Or maybe I've lost my mind..... :crazy:

The rules are a bit confusing. That's why I keep asking stupid questions.

8 tooth at Dallas for sure.

 

For an example of special conditions, when they had the "Extravaganza" scheduled at Modelville, which was cancelled, they had announced 7 tooth option  for the F1 race on the Regal.

 

RETRO needs to clean up their rules pages for sure. Amazing how much confusion can ensue from such brief rules!

I disagree when you say the rules aren't clear. With the exception of that one glitch on the Can Am page, the rules are very clear. I think it's just a webpage glitch that needs to be corrected.

 

But I cannot build a car for a race and go to tech saying "well, Bunky told me the 8T at Dallas". At some point, somebody is going to show up with a 7T and a printout from the website clearly printed "Gears-  Must use 7 tooth pinion only".

 

Will I get bumped from tech, or will the tech guy honor the printed rule?

If I was doing tech, I'd bump you. :laugh2: Racing rules don't specify that racers must show up at a raceway with a complete car when they come in the door. Unless you oversleep, you'll have plenty of time to get any questionable tech areas answered well before having to be in the tech line. For many big races, the raceway will be open the evening before for tuning & get things ironed out.

 

If you got by doing it once, you'll be apt to try it again. :laugh2:  Why set a precedence?

Most races will have a 'track specific' required pinion, such as on a smaller or flat track.  Most of the banked big tracks use the bigger pinion.

There's NO pinion size rules under SCRRA!! Just run what you think works---everybody ends up with the same gearing anyway!!  10 tooth on the King track with RH motors-- 8-9 tooth on the flat track with RH  or 9 tooth with TSR motors.  Nothing else matters.  :)

Why is there a pinion rule? Is it to prevent the motors from being geared too tall, which results in the motors lasting longer? I can't think of any other reason a pinion rule would be necessary.

From the most current version of the RETRO sanction Can-Am rules, here are the motor/pinion rules. 
 

For the Series, racers will be allowed their choice of motors in the Can Am and F1 classes at All BRS/RETRO events. Racers will be allowed to use any of the following motors:

 

Pro Slot PS-4002 FK with 8 tooth Spec Pinion

Pro Slot PS-4007 Scorpion 8 tooth Spec Pinion

Pro Slot PS-4002B Puppy Dog with 7 tooth Spec Pinion

Retro Hawk with 9 tooth Spec Pinion

If the Texas series has wandered off the reservation then it's up to them to clarify. Those are the most current RETRO sanction rules regarding motor/pinion selection.

In the Retro rules it states " All Motors must run and 8T pinion"

 

That is in the RETRO rules that I am reading, strange,

it says in one place that the Puppy-Dog is allowed then in the Can-Am it say only

the PS4002FK and only 8T pinion.

And at the top of that page it has the part you missed - effective January 1st, 2017.

That's not a current rules package. You'll find the 2019-2020 rules package here.

That's Buckeye series, not Texas. But thanks, I think I get what may have happened is everybody except me migrated to Facebook. Now all I need is to see the Texas RETRO new Facebook rules and I'll be set. Thanks Justin

BRS is short for Buckeye Retro Series, which competes under the RETRO sanction.

IRRA and SCRRA haven no pinion rules that I know of. RETRO is Ron's series they haven the pinion rules. They also have no body thickness rules and allow motor changes during the races unlike IRRA .

Paul (Pablo): why is this even in your wheelhouse? Are you intending to come to Dallas for the Two Step? I'm sure you'd be welcomed. It's a great bunch of people!

 

The Dallas Slot Cars Facebook page clarifies that they run under R.E.T.R.O. rules  www.retroslotracing.com.  They don't post here officially. Questions can be asked directly through their Facebook

page and they usually answer promptly.

 

The 7 tooth anomaly is well known, but as far as I know, no one has ever had success with a 7 tooth pinion at DSC anyway. Usual gearing there is 8/28 or 29. 

Some "might" try a 7/27 but it would probably be short on top end at DSC. Kind of a self-defeating move, as someone mentioned accidentally using that combination last year.

 

Kevin: the Puppy Dog reference is in the general rules section and is clearly mentioned in context of the WSC (coupe) class. The Anglewinder rules also allow Big Dog or Puppy Dog

armatures in a ceramic magnet Pro Slot mini motor can. DSC seems to have lost interest in that class, though. It's not included this year and hasn't been on the schedule for some time now.

Thanks Richard, the answer is, I'm building a car for a customer for the Two-Step.

As I have discovered on this thread, the problem is all the cool guys are on Facebook and I'm not.

 

I'm convinced it's 8T for this race, but it sure would be nice, as a builder, if I had the complete rules in front of me.

If it's not a copyright violation, and if I have any fans out there willing to do me a favor, I'd really appreciate somehow getting my burnt fingers on those rules...…..
