So guys, what do you think of custom al parts? The titanium parts are just unreal on how expensive they are. Looks like steel and aluminum will be my biggies along with being able to do custom chassis and so forth. Looking at the properties for the aluminum I will be using, it is stronger than AISI 1018 (which is most likely what current drive shafts, etc are made of) and it is still about half the weight of titanium.

any requests?
