What is a Slipperential?

[Stealth_RT]

I have been running the Slipperential in my RC8e since they first came out. It is a very nice unit, but there are a few things I don't like/would like to see changed:

The teflon ring inside the spur gear wears very quickly and now the spur gear runs a bit off center, making tight spots in the gear mesh. I'll have to order extra teflon rings, but it would be nice if they lasted more than 2-3 weeks before letting the spur gear get off center.

The diff outdrives are WAY too big inside for RC8 dogbones. Any reason they were made so big? Or should I ask, what brand 1/8th uses diff outdrives with that large of an inside diameter? Unfortunately, stock RC8 diff outdrives are a bit too short to work, on at least the spur gear end.

The diff outdrives are supposed to be hardenend, and I guess they are or they'd wear out in 2 runs. But after only 3-4 weeks of racing, they are showing serious wear.

As a slipper pad material, plain fiberglass works OK, but it sure changes its slip characteristics when it gets hot. Was testing done with 'normal' slipper pad materials like Rulon or Teflon?

I haven't done back to back testing vs stock center diff yet. I'll have to reuild my stock with a 46T K car plastic spur gear to keep gearing the same, and see how it feels.

Off topic, but Stealth, what receiver box do you have installed? I have been rigging up an RC8e box to fit my Mugen MBX-6 but yours looks like what I wanted from the get go.

It's an RC10GT2 gas truck receiver box. I made a new top cover for it out of plexiglass, from when I had it mounted on my RCM chassis. I'm back to the stock chassis, with new holes drilled to move the center diff over 3/8". The RCM chassis was awesome, except for the bodies not fitting well and not keeping the dirt out.
