Yeah thats the ones I was thinking of, I'll have a play about with those. Many thanks.

If there is visible wear or stress, I would.

A temporary fix would be a drop of medium or thin CA around the nut, to help hold it in place. You'd be better off with new T-nut part and then CAing the nut in that, though.

Well I just installed my new HPI heatsink motor mount and all I can say is...

Who designed this damn thing? Now I have to put the pinion on and take the pinion off before installing and removing the motor. Arrrrggghhh!!!! Unless of course I run mod and/or binary stock motors with a 27T or less pinion. Something tells me this is gonna be more hassle than it's worth. Especially for me since I swap motors constantly while running Stock and 19T at my local club races.

Default HPI motor heatsink...

yes...it looks nice...and yes it's a pain to install the pinion if you have the motor already bolted to it.
maybe I'll sell this and the get the Open version from Square...

JDM_DOHC_SiR,

for the rear aluminum hubs. is it better to use titanium ball ends to fasten the turnbuckles. or the stock ones is good enough?

Eventually yes, you do. But you don't have to with the stock mount. To swap motors for running 2 different classes you need to install and remove the pinion 4 times. And if you're not a hardcore racing nut and don't do major maintenance to your motors between rounds like me, then it's 8 times vs. 0 with the old mount. Oh well, it's still a nice piece.
