6061 vs 7075 Aluminum for Battery/Motor/ESC Mounts — Which Do You Actually Prefer?

[sos2627]

Hey guys,

I'm working on some custom battery, motor, and ESC mounts for the Losi 5IVE-T and trying to decide on the aluminum spec.
Most of the Chinese option parts out there are 7075, but I'm leaning toward 6061 since it machines cleaner, it's a bit lighter, and honestly strong enough for mounts that aren't taking direct impact.
Curious what you guys think — does material actually matter to you when buying mounts, or do fit and price matter more?

Anyone have experience with both?


Thanks!

7075has higher tensile strength than 6061 but 6061 is easier to machine.

For what you are doing that truck will not know what alloy you used.
