Chassis weight comparison
Chassis weight comparison
There were no significant differences between chassis' weight
have a look
Graphite rules!
Milled chassis dosen't loose weight much, but the V shape nose plate does.

Re: Chassis weight comparison
Pardon the silly question, but why is a 6 gram difference on the nose plate significant, but 7 to 10 grams between the top two chassis and the next two isn't?

It's about percentages. The milled chassis isn't even 2% lighter while the "V" nose plate is nearly 17% lighter.

Ok, but aren't the effects of weight cumulative, making every gram saved an improvement?RichieRich wrote:Halgar wrote:Pardon the silly question, but why is a 6 gram difference on the nose plate significant, but 7 to 10 grams between the top two chassis and the next two isn't?

Re: Chassis weight comparison
Right! But, if you had to pick and if you're on a budget, saving 2% with a worlds chassis doesn't maximize value.Halgar wrote:Ok, but aren't the effects of weight cumulative, making every gram saved an improvement?RichieRich wrote:Halgar wrote:Pardon the silly question, but why is a 6 gram difference on the nose plate significant, but 7 to 10 grams between the top two chassis and the next two isn't?

Got it! Hence the reasoning behind Swiss cheesing the chassis.RichieRich wrote:Right! But, if you had to pick and if you're on a budget, saving 2% with a worlds chassis doesn't maximize value.

Re: Chassis weight comparison
Thanks for the interesting post, gatlin.
What surprises me is the difference between the black and gold chassis. I can understand why the powder coated green chassis is heavier than the anodized ones, but I wonder why the gold is heavier/black lighter?

Re: Chassis weight comparison
Nice post.
Just goes to show what little the BS "milling" really did for the weight. Obviously just something to claim on the latest and greatest version.
I imagine the black one is lighter because lighter/thinner/cheaper aluminum was used. Corporations have a way of cutting costs in ways you wouldn't imagine.
I'm sure I probably pissed a few off with that but oh well.
I've had a few beers in me too.

Re: Chassis weight comparison
Don't forget time in the anodizing tank will effect it as well. You are in essence electronically transferring metal to another metal (before anyone throws it at me, I know aluminum isn't a metal, but you know what I mean ). Back at Roush anything automotive that was anodized, we had to specificy the thickness on the component drawings.... I can remember slip fit parts not fitting correctly due to too much material build up.

Re: Chassis weight comparison
I've read somewhere (probably an old RCCA) that the reason for the milled pockets on the sides was to help direct dirt out of the chassis through the slightly larger holes. The 'H' pocket is probably just for show. The World's chassis main claim to fame is its hard anodizing, which makes it stiffer.bngiles wrote:Nice post.

The weight differences between the black and gold chassis could be deliberate, but not to cut costs; 6000 series aluminum alloy sheets pretty much all cost the same. Perhaps Associated spec'd a different grade of aluminum to simply lighten things up a bit and increase performance.
But, in the end, to put things in perspective, 7 grams is a whopping 0.25 oz .

Re: Chassis weight comparison
now weigh a swiss cheese chassis and discuss the weight savings versus bending the chassis in half if you case a jump theory

my early RC10's chassis has stamped "A" on it. my team car has "B".
and, these new gold and milled ones have "C".
I got same question when I finished this silly weighting job. and, found A,B,C on the chassis.
so, I tried digital caliper. it's 6 bucks cheap and nasty caliper. and it's a still caliper.
the thickness of early gold and black chassis was 1.58 to 1.62mm(0.062")
and, 1.60 to 1.66mm(0.064") on milled and the new gold chassis.
I don't think I got correct value. these chassis made by some pressing and cutting processes. so, the values couldn't be regualr.
anyway, the milling job did work somehow.
the milled chassis is "slightly thicker" than old black one. and, "slightly lighter" than old one.
if these milled and late gold chassis have "C" were made out of same process. milling job saved 10 grams.
but it's TINY differece. I'll take graphite chassis if I need light one.
my conclusion is "Milled chassis looks cool."

I never understood the slots getting rid of dirt easier. ??
