No design weaknes, if they are built correctly the diffs don't come loose, and to be perfectly honest some of the nicest diffs I have built.
I admit, I had a couple of diffs when built came loose, but that was due to the c clip not seated properley. I discovered this by spinning the diff a couple of times, so didn't have to run the car. Just took the diffs out and double checked the c clip. Even, no need to put the loctite on the grub screw as long as it is very tight. As with all my RC Cars I carry a spare diff, mainly to save having to build one when I am racing.
