What's the difference between these two?

Is it the same motor with one being "tweaked?

Just seems like a different rotor. The Maxzilla isn't even out yet though.

They are the same, or supposed to be. Express Motorsports has gone through the motor & checked for any defects & the shims to insure it is the best it can be.
I have never used an Express Motorsports motor but I do run the Maxilla, yes they are available here

There should be nothing wrong with the Express motor, just make sure that it comes with the TEP1112 high torque rotor (Turquoise band)
