Revo Slipper on E-Maxx Tranny Mod :)

So to bring this back up

I have a complete revo slipper kit, I just need the new emaxx 3905 input shaft, and a steel idler? That makes a bullet proof emaxx trans?

Is the RCM one better then the traxxas one? Id rather order everything from tower hobbies, but if the RCM one is better, might as well just do it right the first time
