Classes and Rules for 2019-2020 season

"At this point I would ask anyone who would like to race the Slot.it model to look for some documentation. It is a very good car, one which i would race myself if i could find sufficient documentation."

My understanding from the rules is that Slot.it cars are not allowed.  But maybe I misunderstand/misunderstood.

I am trying to clear a couple of pretty decent slot cars for the LeMans catagory.
I think I can document the Ferrari 312P (aka 312PB) slot.it. ref the #15,16,17 cars in the 1973 race.
On the Alfa, 33/3 I had more difficulty referencing it's Lemans history. The "Tipo 33" refers to a number of different Alfs, both 8 and 12 cylinders. At this point I would ask anyone who would like to race the Slot.it model to look for some documentation. It is a very good car, one which i would race myself if i could find sufficient documentation. The T33/3 driven in 1970 had a 3.0l V8. The Otto Zipper car was raced in SCCA/ and had the 12 cylinders.

We can't run Slot.it or NSR cars in this class.

actually Daryl, the 312p and 312pb are distinctly different cars. The "P" was a 3L v12 coupe that Ferrari fielded in the late 60's after the governing racing body prohibited large displacement cars after the '67 Ford sweep. This coupe has to be one of the most beautiful racecars ever, but unfortunately was not successful.Wierdly enough, probably privateers totally rebodied it as a roadster for the '74 race. The "PB" was entirely different, an open roadster with it's boxer arrangement 12cyl. taken directly from it's F1 efforts. As to involvement in the 73 race, see above entries in this string.And even if it could run, it's a slotit, so you'd probably have to scratchbuild under that body.
As to the Alfa, I think you are right on the configs. I didn't delve into this car as much, but my scratched notes show an entry in 73 as well. The last config, I think the 33/3 had the 12cyl. SRC did a very nice slot of it, and might qualify in our rules. It was highly successful in European sports racing winning at least one championship. But those were not endurance type races.
As I said before, this has been a very difficult class for a guy to field with our rules. But I'm putting the finishing touches on a car and it's backup car. And the other 2 classes I have absolutely nothing for.

Off the top of my head SRC makes two different Porsche 907s, Alfa T33 and a Matra, Fly makes Ferrari 512 in short and long tails, Porsche 911s/917s in short and long tail, 908s. GBSlot has Le Mans Chevrons and Lolas, and Spirit makes a Ferrari 512M and I'm sure I've forgotten some. All will better served, IMHO, with a 3D chassis.

Craig, you are correct. Podded motor cars such as Slot Its like you mentioned are not allowed though you may build a "lesser" brand up utilizing one.

Are 26D motors permitted for the Vintage 1/24 Hardbody class?

[David Asbury]

Craig, Because this is our first season with 1/24, we are trying to limit the performance to before vac bodies and commercial track type motors were introduced. As late purely commercial track motors, 26ds are too hot at 3 volts rating and way higher performance than the standard 16d or 36d everybody is using. If this season goes well we are likely to raise the bar a bit in the future and allow hotter motors. I hope this helps and look forward to racing with you this season as I understand you are really into all things vintage.

Thanks for the response David.  Just to explain a little.  I read the rules and then started looking for a car to run.  I found a 1/24 1960's stock Tamiya Carrera 6 on eBay.  I already had one, but it was in less than good condition.  The one on EBay was expensive and it was in Australia, but it looked in good shape.  As far as I knew it fit within the rules. It has a 26D motor.  That motor came stock in 1/24 Tamiya Carrera 6 RTR's.  slotblog.net/topic/31906-tamiya-porsche-906-rtr/  So it definitely isn't a vacuformed body and I doubt it is a commercial track motor.

The rules excluded commercial motors and motors such as the Cox Nascar and Strombecker Red Hemi (Both 36D's I believe).  No mention of the 26D.  As you now mention, I guess you consider it a hotter motor than others are running.  So be it.


I am disappointed, but I'll get over it.

[David Asbury]

Craig, You can still run your Tamiya Carrera 6 with a 36d in it. I tried the swap this morning and it only took about 30 minutes since the chassis was designed for the 36d . It came with a slightly different hold down strap but it slipped right in with plenty of room for the suspension to move. I will help if you need it. David

Thanks David.  When I figured I wouldn't be able to run in the 1/24th class it didn't make sense for me to make the long drive up there, so I made other plans for today.  I'll consider your idea in the future, though I do not think the 26D motor is the commercial motor you think it is.  As I mentioned, it was stock in the Tamiya Carrera 6 RTR cars.  For sure there are hotter variations of the 26D just like there are hotter variations of the 36D (e.g. the banned NASCAR and Red Hemi).  It depends on windings and such.  I do not believe the Tamiya 26D is such a motor.  As for being foreign, I think many if not most 1/24 slot car motors are made by Mabuchi in Japan.  I could be wrong.  My preference, of course, is to run the motor that came in the STOCK 1960's slot car that I purchased.  Hopefully y'all will re-consider at some point.

I have a "dyno" that I run my cars on at home. I also have a electronic "Tach" that I can and do check some of my cars, checking their R.P.M. at the wheel. I then check the voltage setting, usually 6 volts, and look at the gear ratio. I then double the R.P.M. reading (6 volts) and multiply by the gear ratio. That will give me R.P.M. of the motor. I tried it with one of each cars in the different classes.

Cartrix - 10,677 - S-can - 9/25 gear ratio
Unlimited - 25,711 with a 25K motor
Hard Body Vintage - 22,932 and 23,898 - two different Cox x250 cars. 16/48 gear ratio ( Cox Nascar motor was rated at 32,000)

Craig, If that is your car in the picture I wouldn't race it if I were you. They are so fragile and the RTR with the factory sprayed roof and decals is a very rare car and valuable! Good find. You can probably get a re-pop body and race that instead. David

[Deleted]

Thanks David.  I bought it to race it, but it looks like that's not going to happen.  While I have seen several 1/24 Tamiya reproduction slot-car bodies, they have all been for the Can-Am type bodies.  I have never seen one for the Carrera 6.  The one I bought from Australia came with a spare canopy.  I don't know if it was originally an RTR or a kit.  Both were available in the mid-60's.  


I understand that the plan on Saturday was to allow Mark to run his Tamiya with the 26D and then decide whether to allow them.  I don't know for sure what Mark has, but I don't think it's a Carrera 6.  Tamiya released a dozen different 1/24 slot car kits in the 1960's.  Mark told me he was never allowed to run his.   

[David Asbury]

Craig I do think you have the RTR based on the decals applied to the car so perfectly and the factory painted roof! As for "the plan" my interpretation was different than Marks. We did concede that we don't know all the performance implications of the true vintage products and for those which are UNKNOWN we would "see what happens" but not the ones we do KNOW like the really fast Cox Nascar, Russkit 27 and 26d motors. Or the Cox IFC models even with hard bodies. David
