Default Materials used in RC Cars.

Hi guys, anyone knows where i can read up on materials used in rc cars?
cos im not sure when upgrading certain parts would actually improve performance or if it would actually cause another problem...

Heres what im trying to find out:

- Plastic VS Aluminium VS Carbon Fibre VS Graphite Fibre VS Fibre glass= how do they rank in order of the heaviest to the lightest and in terms or rigidity? ie. any pros and cons of using the material.

- what on earth is SSG Grahpite? Satin Grey? then whats the other S for?

- Titanuim Vs Steel = Ti is lighter, but is it softer than steel?

- Aluminium is lighter and cheaper than Titanium but softer, therefore are they suitable for use as screws?

There is a lot of sources you can get on the internet and one of them if you go to www.mcmaster.com-every block of materials begins with short material description (example page 3428). It might help you with basic guydline.

Hmm... Thanks for the links guys...

Tot i would share what i gathered so far:

DENSITY (g/cc)

Acrylonitrile Butadiene Styrene (ABS) = 1.02-1.21
Fiber Reinforced Plastic = 1.17-2.08
Carbon Fiber = 1.37
Graphite Fiber = 1.47-1.66
Aluminium = 2.7


It seems like ABS parts are much lighter, so now i wonder if making the car more rigid using Carbon Fiber decks are worth the trade off on weight...
