Hey Lincpimp,
How do you plan on going shaft to shaft with a slipper? If you get that figured out, would you post some pictures please? I've been tossing that around in my head for awhile now, and so far I've come up with nothing.
Before you go paying a wad of money for something that IMO is overpriced. Check out what Lucien has to offer over at

I'm not sure what length you're looking for, but he has some things that you might be interested in.
I have a 3032-12 that should be here by Thursday. I'm going to test it in my E maxx Direct Drive setup. But soon, I will be doing an E Revo Direct Drive to Diff with a motor similiar to this. The E Revo will probably have to wait on his 40mm motors, which are supposed to be out next month.
