which metal is lighter titanium or aluminium

im not sure what is lighter but i think titanium is stronger.

Aluminum:

Density in g/cc

Aluminum-----2.643
Aluminum bronze-----7.702
Aluminum, 2024-T3-----2.77
Aluminum, 6061-T6-----2.7
Aluminum, 7079-T6-----2.74

Titanium-----4.5

Titanium's strength vs. aluminum isn't even comparable.

aluminium is strong enough for rc cars.

carbon fiber!

Carbon fiber look's stupid on rc car's, I'm sorry to say!

[X(] carbon fibre looks cool! Especially the blue stuff

Ryan.

carbon fiber isn't that much lighter but it is a whole lot more brittle

carbon fiber chassis and a arms for savage do look cool! you can't argue with that they're so..... something!
strength:
aluminum<titanium<carbon fiber
lightness:
aluminum<titanium<carbon fiber

don't flame me if I'm wrong on any of these...
also even if aluminum is lighter than titanium you need more material to achieve comparable strenght
in other words aluminum stuff will have to be thicker than titanium stuff to boost strength

well im not going to have carbon fiber universals but i think i might get aluminium ones
