I have spent quite a bit on my E-revo drietrain, RCM hybrids coupled with KD cebter dogbones and MIP 1665 cvd's front and rear. all of this has led to a new weak spot, the rive pins in my 23mm hex's as well as the hex's themselves.
I have broken 5 or 6 of these since upgrading the rest of my drivetrain, only when i started to use ground down allen wrenches for my hexes did it stop, and even then i haven't had too many packs on them. Not too mention the
23mm hexes, they aren't that cheap to replace.
As for the rest of my setup, i would recommend all of the parts to anyone looking to stop replacing driveshafts and diffs!
