Aluminum or...

[JERRY2KONE]

It really depends on what you want to do with the vehicle in the first place. If you are in a hurry and just want to race or bash it about, than there are plenty of nylon, plastics, and composites to shoose from that will get you where you wish to be. If you are planning to make a vehicle that not only runs well but is tough as nails and looks like the top dog, then aluminum and titanium is the good choice. Weight is not that much of an issue unless you are competing on the track or trying to break some kind of speed records. Besides with the right metal parts you can have a vehicle that weighs close to what the plastic toys weigh these days, but be strong enough to smash the toys. The final part of the equasion is how big is your wallet? If you have a limited budget then you should stick with the plastic toy parts. Going with the metal bling look will cost you big time.
