Yes, rarely. Released in 1991, AMT/ERTL's kit #8866 modeled the 1980 Daytona-winning Porsche 935.

Decals, Pattos.

AMT made brass chassis 1/24 slot car kits in the '60s. I bought a Chapparal off eBay this year, not built and in the original box. They did quite a few of the Can-Am series cars, I have no idea how many were produced. The AMT model number on the box is 9303-800.

Yes.
 

 
More HERE and HERE.
 
And a typical AMT 1/24 car and chassis (albite not the Turnpike type).

Weren't the AMT sports racers actually 1/25? That is the Chaparral, Lola, McLaren, and Hussein.    

 

Todd, I thought the MESAC bunch ran 1/25 exclusively. When I first got to know Doug he was searching for only 1/25 bodies as that's what the club used. I thought the four AMT bodies were the first he did in resin.   

 

AMT also did the Watson, Lotus, and McLaren Indy cars in 1/25, released as the Hall Of Fame kit and the Watson released in '63 as the Indy 500 winner, "Old Calhoun." The Allstars kits were 1/25, those were the Stingray, Mustang, Cobra, and Thunderbird.      

 

I'm not sure they ever release a lot of 1/24 scale slot cars, if any.

 

That's been a long time, so my memory might be fuzzy.

The AMT Model Turnpike cars released in 1962 were all 1/25 scale slot cars. They had 1/25 scale static models as early as 1958.

 

Sorry, I never noticed that Todd was asking about 1/24 cars by AMT. I saw AMT & automatically thought 1/25.

The LASCM website presented the larger AMT kits and RTR models as being 1/24 scale. This was a generalization, but has now been corrected: indeed the only 1/24 scale models issued by AMT as slot cars are the two 1967 "Thingies", the Fantum and the Bandido RTR. All others are 1/25 scale.

Why are 1/25th scale cars bigger than 1/24 scale cars?

They're not. The 1/24th cars are a bit bigger. 1/24th cars are scaled 1/24th of the actual size of the real thing. The 1/25th

cars are 1/25th the size of the real thing. i.e. it takes 24 of the 1/24th cars to equal the length of the real car. It takes 25

of the 1/25th cars to equal the length of the real car. So 1/25th cars are smaller because it takes one more layed end to

end to be the same length as the real car.

 

I found the brass AMT chassis to be very competitive in the day, when mated with a buterate body. The hard styrene

bodies were too heavy for the chassis to work well.

Dave,

Scale wise it looked to my eye that a 1/25th AMT Fairlane hardbody was way bigger than a 60s 1/24th Champion Fairlane. 

  

Not the math, just that it came out that way.

Model engineers are not known for their acuracy to that 'detail' of correct scale.

Somewhere in history the model industry had a lawsuit about who could produce exact 1/24 scale models and AMT and others lost to Monogram.  Not logical, but one more interference of lawyers in something for them to make money at our expense.

 

PdL might know more on the scale issue.  I think I heard it from a friend at Monogram.

The CanAm series of cars is marked 1/24 on the box, as opposed to the earlier All Stars, but they do seem smaller than similar models by other makers. 

 

Larry, what's the story on the 1/24 lawsuit? Never heard that one before!

The AMT kit shown by n9949y in post #1 was re-issued in 1998 with new box art as kit #30072, but now AMT called it 1/25 scale! 

I believe the Porsche kit actually originated as a Nichimo 1/24 kit but whether AMT acquired the mold or simply re-boxed the Japanese 

kit I am not certain.

 

When AMT brought the Can-Am kits back again in new colorful box art around 1968-69 they too were relabelled as being 1/25 scale!

The real answer to true scale starts with measuring the wheelbase and compare to the OEM 1:1 car.

 

The AMT screw in bumper Fairlane that I just checked comes in at 4 7/8s.

Had to extend (add extension) to a Champion 1st gen SW to that number to try the fit.

 

So...if a Real 66/67 Fairlane is 116" WB then 4.875 is darn close to 1/24 scale.

 

A 1966/67 Champion clear version is 4.50" WB and it's called 1/24... I like that scale better ..LOL

Referencing the Ultimate Car Page, specifications, the 81 Porsche 935 Kremer measured in inches:

Body length, 189.8” (can vary as there were many versions of the 935)

Width, 79.1”

Height, 45.3”

Wheel base, 89.4”

 

My AMT 1/24 body measures in inches:

Body length, 7.6” X 24= 182”

Width, 3.30” X 24= 79”

Height, 1.75” X 24= 42”

Wheel base 3.70” X 24= 88.8”

The AMT's 935 Porsche is very close to being 1/24. I remember AMT's slot cars as 1/25, which is why I originally mentioned the Porsche as being a rare AMT/ERTL 1/24th model.

 

MattB, I’m not  sure from your post you're commenting on MESAC or Pelican Park. Doug Haynes of Pelican Park made 1/24th scale molds.  From the late 90’s to his death in 2009 we Pelican Park members had discussions when he making molds what proper 1/24th dimensions fit the particular car body he was working on. At Mesac in the 1960’s we used both 1/24th and 1/25 bodies. In the early 1970’s Roger Moon who was that club’s master mold builder for pulling Butyrate bodies made a BMW 3.0 CSI, a Lotus 47 “Breadvan,” a 71 Camero and ’72 Greenwood Corvette that were in scale more 1/25th than 1/24. In the ‘60’s MESAC members used many of Les Asbury’s 1/24th Lancer bodies as well as Ron Klein’s 1/24th bodies.

Todd, I thought it was a carryover from MESAC that you guys ran 1/25 only.   I vaguely remember a conversation with you about 20 years ago asking me what bodies I did in 1/25.   Looks like my brain has short circuited!  Again!

"it looked to my eye that a 1/25th AMT Fairlane hardbody was way bigger than a 60s 1/24th Champion Fairlane".

1960s vacuum formed bodies of stock cars were generally copied on  existing injected bodies used as a general pattern. Case in point: International bodies that are clones of AMT, Jo-Han and MPC injected jobs. The only concern for vac formed slot car bodies pattern makers was... width and wheelbase, to fit 3" wide chassis with 4.5" wheelbase. The rest was irrelevant, and as a general rule, all these bodies were summarily categorized as "1/24 scale" regardless of their actual size.
For example, the Monogram Kurtis Midget body and its driver are closer to the 1/18 scale, but are called by all "1/24".

But there is no doubt that the AMT Can-Am bodies (Chaparral, Lola, Cooper-Hussein and McLaren-Elva) are substantially smaller than their competitors branded as "1/24 scale", especially the Cox Chaparral models that are the closest to actual scale models of the real cars. AMT kits, even if named "1/24 scale" for marketing purposes, followed the general company rule of making 1/25-scale models, so that the larger ones would fit inside the static kit boxes and gross cartons available in standard sizes.

More recent AMT and Revellogram model kits adopted the true 1/24 scale, but these companies are very different from what they were in the 1960s and priorities have changed.

Now the real question is, who cares? Let's consider that @5-inch bodies are "1/32" and the larger ones "1/24" and peace on earth to all.

In slot cars;  to serious scale guys.

Some RTR or kits look right and some don't no matter what scale it sez on the box.

I even like some Womps bodies what scale are those to be?

 

 .... It's what looks right, works right .. is right. I see it as proportioning of body, tires and WB for intended use when it comes to slots.

 

Static Models, scale relevant. 

Different proportioning looks awkward when parked on a shelf next to a different brand's idea of the word.

Whatever fits inside the standard Parma box.
