I installed the MIP race duty CVD's on my Tellup4de about 2 weeks and 8 packs ago. I have bashed it and the MIP's as hard as I can so for. Big air and hard landings, full speed 100 foot cart wheels. Hard slides where it would end up rolling backwards and then going full power forward. The MIP's are holding up just fine and were a simple install. There were 2 issues early on however and I will explain but first a brief description of what I am running.
Traxxas aluminum C-hubs
Traxxas aluminum steering knuckles

And the week link that I will take care of soon---Traxxas Stampede 4x4 plastic a-arms.
Issue #1- I had to lower my ride height because the dog bones would come out of the diff cups. What made me scratch my head was that it only did this when I cartwheeled my truck.
Issue #2- In sandy or dusty conditions the grease will become a lapping compound so I removed the grease and used WD-40 before, during, and after my bash sessions.
