This is a direct replacement for the stress-tech plastic controle arms that came with my 1/10 scale MT. They're simply made of 6061 AL. Since the plastic parts tend to break in cold weather i thought it would be a good project. The Process consisted of milling rough blanks to size, making a fixture, programming in MasterCAM and 3 operations on a 3 axis Feeler machining center. The end result adds a few oz. to the truck's weight, but it's lower center of gravity should help. Any Criticism is appreciated.
