"The new car starts with a black, hard anodized aluminum chassis made from a new material which is stronger than our original chassis, and comes with the bottom of the chassis already milled out like our Team uses."
My apologies; the World's chassis alloy is 2024-T6. It's on the flap side of the World's Car box. 2024-T6 is also much stronger than 6061-T6, but not quite as strong as 7075-T6.

That's awesome information. Thank you! Is there by chance a picture of this somewhere?
I got both of my Worlds Cars second-hand, so I have never seen the box in person.
Well. I can tell you why the chassis were milled. One -was weight. Two -was to provide a channel under the batteries for the speedo wire. Three -was to provide a channel for dirt that collected in the car to find its way out via the holes. This was from Cliff Lett, and he should know.
And sorry, I just have to set this straight, there is no way in hell that removing material from the chassis will make it stiffer. At least not in our universe. Yes, milling away material will add surface area, but this is only useful in heat dissipation. And no it is not like "bead rolling sheet metal". They are two completely different concepts. In bead rolling (or stamping for that matter), you are taking a given material and forming it into vertical surfaces. This does several things, the two most important are - Firstly it adds MANY times more material in a previously un-represented dimension, and two it work hardens the material. This process does add stiffness in the directions of the bends or ridges. Removing cross section from a given thickness of material will only make it more flexible -period. It is physics, if you dont like it, not my fault. if you make it thinner it will flex more. And BTW, you are not adding vertical surface during milling, you are REMOVING it. All the material removed WAS verticle surface area.
AS far as why the Graphite cars were never really adopted by the "Team". Because they did not handle well. The graphite chassis cars (kit ones anyways) were much lighter, and this made for a whole gaggle of issues. The single layer chassis made for a rather flexible car. Not necessarily a problem in and of it's own, but the fact that the CF/Graphite used for the chassis did not absorb energy as well as the aluminum chassis made the cars handle poorly. Rather than absorbing energy like the tub cars, the chassis would return the energy to the suspension and make the cars unpredictable.
Like everybody else I'm building a WOIN Worlds car. To my knowledge everything is original. I've seen posts about the Klein arms, RPM Worlds arms, and CE arms. My question is, is the AE worlds arms the same lenght as the RPM Worlds/Klien Arms, or...

the b4 and b44 universals aren't that much different. If you are using the wheel spacers and b44 universals, you should be very close to where you need to be with b4 wheels. With b4 universals and b4 wheels, you should be as wide as a b4 +- a mm or...
Hi all. Nice place you have here. I have just completed my RC10 World's buggy. The only thing that seemed to be a problem was the transmission. It is notchy when you try to turn it by hand. I had read about the trans problems on this forum before I...

Long whip antenna....check! 8) I signed my autograph on the body to give it that finishing touch. :lol:
Ok, I preparation for my World's build up, these are the questions that I have come up with:
1. What color are the rear axle/bearing hubs? White or black? The manual shows the car with white, but a pic of the parts in black.
2. What color are the...

Got the rear wheels today qc, Thank you sir! Just need hoopty's Krylon or some white bell cranks.
Well......I picked up a 'mostly' worlds car from ebay recently, kind of jumped the gun on the bidding, threw a hail mary bid, and actually won. I got the car but it's pretty beat. Looks like it was a solidly raced car. Kind of glad I just barely...

yep, they are not too bad, just worn from slapping the ground in the front and back. Those parts will be re-dyed black and used to replace parts I scavenge from some other cars I have.
My plan is to convert it to about 90% real black worlds car. I...
Need some info on chassis. I know the difference in a slimline and a junior chassis (side pods and all), and between x2 and a pro chassis. My question is how does the wheelbase on the prose and the junior compare with the pro and the x2.
Reason...

hello,
The original jr chassis was about a half inch shorter than the pro/xt/jr2 chassis. Using this chassis will give you better steering, but the chassis only has a 20 degree kick. The later chassis have a 30 degree kick.
I have the Tamiya Hummer and its nice but not much on power? does anybody know how much it can take? I was thinking of putting my brushless in it and take it for a spin. but I dont want to blow it up? I am going to brake it down install bearrings....

What about TA04 onroad chassis? Think a 15T double motor is too much for it?
