Which car in any category , do you think has the best aerodynamic body ?

I'm a Thingie freak , and I can't go past the Dynamic Bandit . Its simplistic Open Wheeler stance and well contoured shape , is just brilliant ! Sure , on long tracks , the 36D powered cars leave it behind , but as soon as the corners arrive , it's out in front again . Just a pleasure to drive . The Super Bandit was made to keep up with the 36D motors on the straight , and had the hotter Green Hornet motor . But unfortunately after about 30 or so laps , it would start to become alarmingly hot and slow down , or even burn out . I was also not impressed with the paint job on the Super Bandit , that chocolate brown, done nothing for its supposed hotter status . But the colour of the normal Dynamic Bandit in Root Beer , was most impressive.

Thanks for the correction, Spurman. Two typos suggesting Ettore Bugatti's Type 57 arrived at, and won, at Le Mans 100 years too early. Bugatti won at The Sarthe in 1937 and 1939, of course.
My Super Bandit is black. I don't like Bandits at all. Mine would be gone if I hadn't quit selling o Ebay
For aero, I like the Banshee, Testors Maurader, and Stinger. The Serpent and Gamma Ray are surely great aero, but not cars I really care much for. After market Shinoda bodies are pretty well designed for aero. Of course one of the best that hasn't been mentioned, the "Cuc".

I've often wondered if you could make a lexen clamshell body utilising F1 ground effects that could use the slot grove as well as the under body design to take advantage of the high speed that can be achieved on the big banked tracks like the blue king and the like!🤔
I'm sure you could get a significant amount of suction that would be able to find a place in the future of slot racing!
Cheers,
John.
Zig, John,

When Rod & Custom magazine did their "RTR Roundup" in the January 1966 issue, the Viper was considered the best all-around performer.

Don, you don't think that Classic may have been one of their biggest advertisers? I would think the Bandits would easily have been better runners than the 36D Viper. Most any "best of" decisions come down to what type of track, what type of cars work best on that test track and other factors including whether it is open wheel design or a full fendered car. Buying ads in the magazine probably also help.

Remember the MPC Dynocharger was advertised as the fastest production slot car, as was the K&B Blue Monster. There were several motors advertised tobe the fastest production motors.

I never figured there was any validity to any "best" item. It seemed like every slot car tested by the magazines got positive reviews. That is ok, advertisers made the magazines possible and they have helped us save and learn th history of that period.

That's exactly the point Matt: The R&C article was the only review that included actual lap and drag times, which theoretically don't lie.

Agree that all the other reviews were necessarily positive, to not offend advertisers, but this one really seems fair.

They also kept the cars stock and explained certain shortcomings in the notes: Russkit and Rannalli were geared for shorter tracks, for instance, and for the MPC Dyn-O-Charger, they said the same thing as everybody else: "well, maybe it is really the world's fastest production car, but the amps just weren't on tap for the car to really show its stuff.

Also, remember that the mag was dated January 66, which means that the tests were done at least 2 and probably 3 or more months earlier - before the Bandit and a lot of other cars were released. This was really the first big wave of RTR cars, which was probably the reason for the article.

R&C had a lot of slot car advertising for 2 years or so, but don't think that Classic advertised especially in R&C; they were big advertisers in Model Car & Track, also California based.

Good points Don. I kind of think most of those old reviews wee tongue in cheek! As a kid they made that stuff look really appealing. I still like paging thru the old magazines and enjoying the articles, even though they don't really mean much anymore.
to my eye, the Classic Serpent shown above will always have it. Wish I had one now!
A Super Cuc hasn't appeared here in a while, oh wow! Thanks Matt.

John ,
Once I placed another guide on the rear of a car ( not in a competition race ) , but testing with my serious racing mates . They couldn't figure out why I wasn't coming off , and how did I break the track record by almost a 1/4 second ! I owed up eventually , but after I wiped them out !
Tell you the truth , 2 guides on a car , is quite boring to drive , basically , the controller is just about on full squeeze . But it was fun years ago to see the reaction on the colleagues faces . They couldn't work it out !

of course that's not "aero", but with similar effects. A number of the vintage "toy" type sets featured pins at the back; seen them on VIP, I think Eldon, and I even have a Monogram F1 set car with such! Bernard could fill us in more.
I was thinking more about how to use the air loss of the slot gap with the vortex of the ground affect and the diffuser to an advantage not a loss,
Zig . Not a guide. I have done that before myself.
John.
Would you not need extra ground clearance for ground effect? That would raise the centre of gravity and make the car slower.

Incidentally Troby (French) slot cars sometimes had a second guide (pin) at the back. And yes it would be boring to drive, like magnatraction is.

Your point above reminds me... You might like to look up the fascinating development of Russian Ekranoplans in the 1950s. The Russians pulled the financial plug on the project, whilst Germans tried to resurrect the technology in more recent times. Jus' sayin.'
Interesting Trisha, that's basically what ground affect is in motor sports today,it just upside down!
John.
Yes indeed, I've watched more than one thing on YouTube about Ekranoplans. A slot version would be interesting! :ROFLMAO:

Jim Hall is credited with bringing underbody aerodynamics to the Indy 500.

Not to take anything away from Hall as I read he was playing with under body shape also.
Credit is a funny thing.
Found this also... Lola hmmmm

The Chaparral 2K is an open-wheel racing car chassis, designed and built by Lola Cars that competed in the CART open-wheel racing series, for competition in the 1979 IndyCar season, and competed until 1981. It famously won the 1980 Indianapolis 500, being driven by Johnny Rutherford.


The 2K was a Formula One-inspired ground effect Indy car designed by Briton John Barnard. Debuting in 1979 with driver Al Unser Sr., it went on to win six races in 27 starts over three seasons. Its greatest success came in 1980 when Johnny Rutherford won the Indy 500

Shawn Buckley began his work in 1969 at the University of California, Berkeley on undercar aerodynamics sponsored by Colin Chapman, founder of Formula One Lotus. Buckley had previously designed the first high wing used in an IndyCar, Jerry Eisert's "Bat Car" of the 1966 Indianapolis 500. By proper shaping of the car's underside, the air speed there could be increased, lowering the pressure and pulling the car down onto the track. His test vehicles had a Venturi-like channel beneath the cars sealed by flexible side skirts that separated the channel from above-car aerodynamics. He investigated how flow separation on the undersurface channel could be influenced by boundary layer suction and divergence parameters of the underbody surface.[2][3][4] Later, as a mechanical engineering professor at MIT, Buckley worked with Lotus developing the Lotus 78.

Yes,I have watched a interview or a doco were he was talking about how he worked it out with his indie car , quite interested! If it wasn't for the slot in the track the slot car could be built much the same!
John.
A little more info, thanks Martin. If there was somebody playing aorund with the aero under the body, you know JH would have been interested and pursued it. I guess most all racing innovations came from several people but usually one person ends up getting the credit.

I'd have to get out my book on Offenhauser to check this to be sure, but the Offy is such a great design and maybe the best designed racing engine ever considering how long it dominated and how many times USAC changed the rules to finally kill it off. Leo Goosen, I think is the guy that actually engineered it. His name is never mentioned outside people that are intrested in the history of that era and Offenhauser, Dusenburg, and Goosen and read about those days.

Sounds like the under car aero is somewhat the same story.

I found an answer to the original question.
Look to nature, it has had millions of years to come up with the best shape for a given task.
I give you this,
