Aluminium or graphite for carpet?
I heard and read many opinions about it, still not clear. What do you recommend for a small twisty and grippy circuit?
#2
I've always used
Aluminum-Indoor Carpet
Carbon- Outdoor Asphalt

I've done the same pretty much
Carbon- Asphalt
Carbon - Grey ozite or Alum for a highly built up groove on grey carpet
Alum- CRC black carpet / ETS carpet ( I would assume on the ETS carpet as I never personally tried that carpet)

The question is, how good a driver are you? Do you wreck often? Or generally pretty clean? Aluminum can be fairly flexible if you get the wrong one, but it is generally heavier and helps bring down the CG. You can make a carbon chassis pretty stiff with the right options. All top deck screws, center stiffener, connecting servo and motor mount to top deck.
But it what goes back to my original statement is, aluminum is great, until it’s not. By that I mean, once it bends, it’s done. Carbon can take a lot more abuse before it breaks. But unless it actually cracks, it’s still good. It only takes the smallest bit of tweak to ruin a high dollar aluminum chassis.
so choose wisely.

Actually just came to post this very same question!
I swapped my Roche over to the aluminum chassis for black carpet last weekend, but am racing on the gray this weekend. Not sure if I should run the aluminum on the gray carpet or swap back to the carbon. Anybody have experience that could weigh in?

I see aluminium is the way to go. I will try both the IF-14 alu one and the 7075 that is thicker (and heavier). Thanks guys!

How are things now? Is really aluminium winning on carpet? It is strange thing to me that one can't do winning chassis with lighter materials?

Aluminium is generally too stiff for asphalt, but another big reason is the alloy chassis scratches up pretty bad outdoors.

The two materials also have different damping qualities.
Aluminium has more natural damping, which is good on carpet where you want a less edgy car.
Carbon has less natural damping, so is more responsive, which works better on asphalt. It also has more flex, which is also better on asphalt (up to a point).

For ETS carpet, I've always noticed on my carbon cars that they are more responsive but also on high speed corners and quick changes of direction it seems to be a bit unstable and noticeably flexing a lot (chassis almost looks like its fluttering).
Aluminum on the other hand the car is much more consistent, giving me confidence to push it further.
Anyone tried a thick carbon chassis say 2.5/3mm? How does it compare to aluminum on carpet?
