Here is one of my winter projects for my XB-E.
Like others, I kept bending the front center drive shaft, and tore up a few gear boxes. I got the to thinking about it and looking at it rand realized the problem was the chassis was significantly flexing just in front of the center diff / motor mound. I noticed that there was a significant gouge on the chassis where one of the screws on the motor for the end bell had been hitting.
My solution to this was make a brace that ties into the motor mount, and runs under the front center drive shaft. I have the 7075RC motor mount which raises the center diff shaft so it made fitting the brace under no problem. I milled the brace out of 6061, and milled a slot in the motor mount to make sure I had a solid connection between the two. I a using two screws to hold the brace to the motor mound. The bottom screw had to be a flat head so it would not hit the spur.
I have taken some hard nose landings with my new brace, and no drive shaft damage or diff case damage has occurred.
I even accidental tagged the curb coming into my drive way, and no drive shaft damage or diff case damage has occurred. Now that one did bend the two lower sus arm mounds and bent the chassis a little bit under the front diff (had to hammer it out a little), but the brace held up with no damage.
I realize that not everyone can get access to a machine shop, so maybe Ol'Fart could make something like this an option for his motor mount.
