Spiral cut vs. Standard diff gears

[simplechamp]

That's what I'm looking for, low maintenance. It seems steep that I just dropped $200 on diffs, but over the life of the car I think it will pay off. Won't be spending all my money on Traxxas diffs every few runs, and won't be spending all my time rebuilding them.

Now it's just finding/making a REAL center diff. I have been reading up on the one cowboy had created, but the thread petered out long ago and there's been no talk of the hybrid center diffs since. I don't see the point of using the Traxxas one. All anyone seems to do is get it and then try anything they can to lock it up again. Might as well just keep the locked spool until a true solution is found.
