What is a Slipperential?

[RC-Monster Mike]

Perfectly normal and acceptable temps. The center diff in my Losi truggy would routinely be 150-165 after a run......without a slipperential - the heat was generated mostly by the drive shafts rubbing inside the drive cups(front was always very hot due to the angle). The Slipperential cools itself pretty well - unless your slipping it halfway around the track, temps should not become an issue at all( and if you have to slip the slipper halfway around the track, you are probably running too much power to begin with). :)

OK thanks that what I was thinking (never temped a stock diff). Just wanted to know if it was normal. Great engineering effort on this thing, works very well.
