CA is the abbreviation for Cyanoacrylate. It is the generic name for cyanoacrylate based fast-acting glues such as methyl 2-cyanoacrylate, ethyl-2-cyanoacrylate (commonly sold under trade names like The Original Super Glue and Krazy Glue).

Don't use WD-40 on anything on your heli, or fine machinery, guns etc. It leaves a residue over time and it's really not oil at all. It is really intended to dry out components. If you must use an oil, use a fine low viscosity machine oil like gun oil, or maybe 3-in-1, but if you want to lube the shaft, I would put a drop on a cloth and wipe a one molecule thick layer on it then wipe it off with a clean cloth several times. I have never lubed my shaft (ahem - helicopter shaft) and it works just fine.

And yes, you want the BLUE Loktite. At least that's what the LHS told me.
