Is a brushless conversion without the two-speed, and that's pretty much how I see it also. Even though you come off the gas and save the drivetrain from the big hits of jumps, off-roaders frequently come off the ground in the straights, (while under heavy power) and I am quite sure that that spells disaster for the complex internals of a torsen diff. The stresses placed on a diff by an onroad car should be much less, and maybe I can get some of the performance of the cars on the road today using these type diffs. I was thinking of starting with just the center like Audi's legendary handling Quattro's have (http://www.audi.com/audi/com/en2/too...ferential.html), and maybe moving to the front and rear later.

I have read in many places, both rc and 1:1 scale. I have especially searched in foreign forums that cover rally game type cars, but nothing seems to be out there. The reason I started this thread was just for some hypothesizing specifically about an onroad application, seeing as that rally game type cars are just getting popular here in the states. One thing I do know is that later if all goes well, I will spring for some Nuova Faor or Fioroni torsens after I run through some trials with the Ofna's, but the sticker shock on them is a bit much to experiment with.
