I use cast alum parts on my cars, many times.

A lot of people ask me about the strength of these parts.Of cource I couldnt compare billet - cast, alum.
But with the right metal choice I can make stength and elasticity , cast alum parts.
No small holes,with elasticity is that I want.

So, I made two cast alum parts (using Vass 's alum secret formula....), one for a crash test and one hub, for spare use.

Watch it.

The hub on lathe and the bright metal. No holes.

You could see metal's quality from the burs.

RE: Cast alum parts

You should take a cast part and mount it to a rolller board and sling it into a wall as simulated R/C car speed. Looks like it would withstand just about any crash, well almost.. Great work.

Wish I had the capability to cast some of the parts I plan on making and just finish machining them. Roughing down to size can take a LONG time.
