I don't have experience with CEN's 1/5 trucks but there is some info about them on their forum under New Products, I believe they are another brand with some changes specifically for CEN only and a different motor (not sure what motor it is.). I haven't heard or seen anyone get one of these trucks.

I do have experience with the 1/8 buggy/truggy and own a GST 7.7 and their stuff is built solid. The GST is an awesome truck and is huge, has mega power and jumps amazingly. I had mine out a couple weeks bashing it along with my brothers slash, it looked like an episode of monster jam when I drove over the slash. However their customer support is lacking and the buggy and truggy designs are outdated, the keep promising new stuff, but nothing shows up....
