Also use it or Blue removeable on the endbell set screws. It would be a really BAD thing for the endbell to come loose from the shaft.

The E maxx output shaft is 67.6mm long. It is 6mm in diameter. If this length is compatible, it's much easier to turn the hard stuff down to 5mm for the drive cup fit, than it is to drill a hole in it. Just put it in a drill press, spin it, and use a file on it or even a Dremel tool. But if you are satisfied with yours already, then it's all good. The set screws should hold just fine with some loctite.

Blue medium strength is what I use on everything. It's already on the set screws holding the shaft, and on the set screws holding the cups to the shaft (and on the end of those set screws).

The E-Maxx output shaft, if 67.6mm long, is actually just about the perfect length for the motor. However, it's got that big chunk of metal in the middle, which would take a while to turn down or cut off.
