Only problem with the E-Maxx output shaft is that it's 6mm at the ends (like the Revo is), but the MT2 uses 5mm outputs. Also, I think the E-Maxx output shaft would be too long to fit on the chassis. Good idea though!

Sometime I might try that dehardening and rehardening method (with the steel shaft, of course ). But for now the holes are deep enough that there are set screws sitting in them, and it's a very solid fit.

Use a medium to removeable strength locktight for final assembly. I put some in the hole before I put the set screw in. The low viscosity Green Medium Strength by Permatex is my top choice for this. The set screws will still break loose with an Allen Wrench, plus it wicks into the space between the endbell and the shaft. This helps strengthen things. 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.

Hey JohnRob, You gonna make a thread on your build? I would love to see some pictures.

My E Revo is currently waiting on more upgrade parts.

1. 125amp Quark Monster Pro - I will do a small Cap mod to it, mount it with some thermal compound to the Aluminum ESC mount, then I intend to eliminate the 4mm connectors and the extra wire length. I'm going to go right down through the top of the ESC mount to the motor. About 2 inches of wire is all there will be from Motor to ESC, Once I settle on the final motor that is.

2. Castle Creations 10amp BEC. I'm going to make this a permanent fixture for this setup irregardless of what Battery setup I'm running. It's more efficient and takes that much heat further away from the ESC.

3. Custom wound 4130 - I'm still waiting on my 22Ga. 392 degree winding wire to get here.

I wanna crank this thing up. I'll make some more Video's too.
