What is the reason that 1/8 buggies have a center diff but in 1/10 electric 4wd buggies noone uses 3 diffs.

Design practicality.

As all current 1/8th buggies are mid-motored, shaft driven machines, the design lends itself very easily to using a 3rd diff. Having a 3rd diff helps take some of the shock loadings off the transmission, too.

On the much lighter, usually belt driven 1/10th cars, the extra rotating mass - plus the fact that integrating a 3rd diff wouldn't actually be easy to do in the first place - means that we race 4wd electric buggies with only 2 diffs. Slipper clutches reduce the shock loadings, so electric buggies still enjoy reliable transmissions. Most people agree that 1/10th buggies actually handle better than 1/8th buggies.

The S2 is outdated..and the S3 is a bit heavy. The car looks good but I believe the S2 was a little better for U.S. style tracks.

Electric races are usually held on smooth tracks and outright acceleration is a must, hence no center diff. A center diff allows an 1/8th scale buggy to accelerate through ruts.

Anybody remember the old Schumacher Cat's? They had center diffs and we replaced them with solid layshafts (ditto the old Lazers) the lowend torque of electrics would effectively turn the things in front wheel drive cars. Everything is different with a 7.5 lb 1/8th scale and all that mid to high end power.

Taylor James and Richard Saxton seem to do well with their S3's.. the new version looks very nice

I've had plenty of Schumachers, never saw a center diff for one though.

You most likely blew the switch. Or, you just forgot to plug your RX pack into the switch and just plugged it straight into the receiver (which is what I do anyway, because switchs are really unreliable IMO).

The original Schumacher Cat had a layshaft that was a center differential. These date back to 1989, Masami Hirosaka made the car famous buy building one box stock in his hotel room the night before winning the world championships in his first race with the car.
