The Losi gets hot largely due to the angle on the shafts - same thing happens on the 1/8 buggy and truggy. The diff helps handling on a track, though.
I do plan on making a mount and CD setup for the rampage xb-e in the near future. I will likely use a 3rd rampage stock diff with a custom gear and rear shaft. The Baja diff is a possibility as well, but would require custom diff outputs and spur as well.
