I had a mslt as well. Tried just about everything to make it work, but no luck... Ended up with a ball diff in the center and modded viscous diffs front an rear. Had about 20 runs on it when I sold it, and I took a massive hit, just wanted rid of it...
I had a MLST as well. Just used a 2s lipo and the viscious diffs. It was kind of fun to play around with indoors, maybe outside if I found a smooth dirt surface,
