brushless 1/5 4wd conversion about to begin! couple questions.

The Etti's are extremely popular and well built! Lots of boaters use them with great results. The CS is pretty good as well.

do these esc's have brakes or not?

That gear is big. Seems like the whole thing could be thinned out,maybe 1/8, and then a smaller section out of the middle "counter sunk" where it botls to the locker.

Is that gear hardened?

The sdp gear will not be hardened. May be the only issue with it, depending on what pinion gear you plan to run. I would leave it full thickness, or only mill it down to match the teeth width on the rcm mod 1.5 pinions.

Yeah.

i am just gonna do like what you said Kaz and mill out the central area of the gear so that it sheds some weight and mounts up properly to the drive shaft but still is very wide. it is not hardened but i have to tell you it seems way stronger/harder than the gears that i have that are hardened. plus, there is a company here local that i could have harden it if needed but i dont think this gear is gonna have any issues. and acutually the rcm pinion is wider than this. the sdp gear is 10mm wide. i havent measure the rcm pinion but i would guess it is about 14mm wide.
