I have lost a few 64p gears. It was my own stupid fault for using crappy set screws!  RetroPro is my favorite class!  The ORS does it right.

At DSC using RETRO rules (.790 tires) we use ~38 tooth 64 pitch spurs.

I don't have any comparably sized 48 pitch spurs handy, but my quick calculations indicate they wouldn't clear.

Where did this 48p idea come from? I have used 64 and 72p since the start of ORS and never lost a gear. How is 48p better?

 

48 pitch is much stronger.

When I would ask others about attrition in RetroPro, easily, spur gears, get mentioned the most.

Anyway, I think ORS going to slower motors, is a great idea.

I also agree with some of the points of Mike Shepard's post.

The lightweight RetroPro chassis leave me cold. That's why I think the UK Tottenham class is so cool. I wish we had something like that around here, so we can see some "real" Tony P anglewinder chassis. Ones with some soul.

I do agree with that, Mike. X12s/BD with a 110 gram weight rule might make for driveable cars that look cool like the Totems.

The PS 4002FK took the motor building out of the equation and made the largest increase in participation. If the cars get too light there may have to be a minimum weight rule. At this time though the racing is cleaner than it was with built motors.

Does anyone sell 48 pitch spur gears with a 3/32" bore? Parma once had a few, but I don't know if they still do.

 

I bought a Cahoza 28 tooth 48 pitch with a 3/32" hole last Friday. Personally I found my cars ran better with 64 pitch than 48 pitch.

Assuming a PS 4002FK motor, at .055" rear clearance with .790" rears, what would be a good starter gear ratio?

 

Also, according to the IRRA® rules, RAW/Can-Am Plus, either coupe or open bodies are legal?

 

What's the difference between IRRA® and ORS rules for the class?

ORS rules were developed to have a faster class than just Can-Am. The majority of the ORS racers felt that the IRRA® rules would be little different than regular Can-Am. They were based on left coast RetroPro rules.

Jim, these are the only rules other than the SoCal group that are in regular use. Don't think there has ever been a race using the IRRA® rule set or the RETRO ruleset.

Bill, not sure what you mean by "a race" but Dallas Slot Cars runs Anglewinder under RETRO rules every month.

The Texas Two-Step in November also ran the RETRO Anglewinders.
 
Major difference is that RETRO uses the Big Dog motor with ceramic magnets.

Sorry wasn't aware of the Texas series. It doesn't get much coverage on SSlotblog or OWH and haven't seen much on Facebook either.

Where are the results listed? I like to keep up on any AW classes.

Thanks, Bill.

 

I have a direction now.

 

Save me some time. Who stocks those approved bodies?

Love the Retro Pro class for some its not the way to go car's are faster and can be a hand full just like GT12 on a King pro bodies and 1 driver that can't keep up can miss up the whole field 

 

But still love it

Maybe Baby Retro Pro with 4002FK motors

I can definitely agree, at least in my lone AW start, that the cars have a "knife-edge" to them that's difficult to wrap your head around when compared to the Can Ams. 

 

With Can Am and F1, the smoothness comes naturally thanks to the cars' having a natural momentum and they swing around in very pronounced fashion. The difference between a good lap and a bad lap is both obvious enough to catch and gentle enough to not cost you the entire lap. The Anglewinder felt more jumpy with the FK torque and brakes, and generally they reacted to sloppy or tentative driving with a lot more violence. 

 

Not a BAD thing, I definitely want to stress! But it means you bring a different skillset into the race.

At least for the SCRRA racers at Buena Park Raceway, past results show the AW Coupes on the flat track have higher lap totals using the same Retro Hawk motors and coming in at a similar weight ( 105-120 gram range).  The spread would probably be greater if Ti-22 bodies were allowed rather than the higher profile coupe bodies. Nothing handles better than a well built Anglewinder Coupe.

Perhaps I'm still in a haze from just returning from my Baja Ca vacation, but, are we talking about Retro A/W's that we use at BPR twice a year or RetroPro cars? My original posts was regarding our twice a year A/W Coupe's. I do not run RetroPro, so opps If that's where this thread was going.

this is not about SoCal racing. Tom   Back east they race R/P with 4002FK motors less power should be easier to drive

Dallas has a monthly Retro day, fourth Saturday of the month. They have a flat track built by Ogilvie.

They post to FB as the day progresses with full results usually later in the evening.

They usually have 8 - 12 F1 entries, 14+ CA and 8 or more Anglewinder, which they term Retro Pro.

 

https://www.facebook...dallasslotcars/

 

They don't use SlotBlog, the Texas Retro thread here is pretty much dead.

 

Personally, I don't care for the "Retro Pro" designation. It's just another class of car.

RETRO calls it the Anglewinder class and intends it to represent the second generation CanAm.

 

Any Retro driver can compete. The cars aren't that hairy. Some might argue that they are easier than the inlines when set up right.

Jim,

 

I bought one of your anglewinder chassis a while back off eBay advertised as a RetroPro chassis. Much too heavy by todays's standards so I had the front axle changed back to 3/32", added some weight, and it performed quite well in our flat track anglewinder Coupe races.

RE: Michael Shepard's #9 above

 

I think it's correct to have this class mimicking the straight front axle era. IRRA® uses 3/32" axles with Can=Am tires while RETRO uses 1/16" minimum axle and .6 diameter wheel, allowing O-rings.

 

If the slightly later development of L-frame hinged axles were allowed, we would be making the front wheels irrelevant again, leading to Retro anglewinder becoming a scratchbuilt Flexi car.

 

BTW: RETRO has a Flexi class.
