Big debate on one of the other forums regarding the Losi Smart Diff not locking up enough. Here is what I think:

"Actually for off road you don't want the diff to completely lock. That was the problem with the Torsen diffs and to a lesser degree the Kyosho LCD diff. They locked up too much and adversely impacted the handling (causing inconsistant handling). The beauty of the new generation of diffs (XRAY, Fioroni Traction and the Smart diffs) is that they have a much smoother action and don't completely lock up. Like having 2K and 7K diff fluid and being able to select between the two depending on what you need, very cool. Diffs that lock up are ok for on road and crawling but not so good for off road."
