XRAY - Model racing cars

Have a look in the FK05 FAQ thread:

Usualy it increases roll center i belive. other than the small effect on roll. it raises over all c.o.g.

Tony,
I have been curious as to why this feature was not included in the T2. Was it something that no one ever needed to use - I have always thought that while a possible effect in theory, it would never be noticable on the track. Admittable, I've never owned the model that had this feature.

Oh, it was definitely noticeable, but for the most part we all tended to run the standard middle position anyway. I guess in the end Juraj decided a quick change design was more important than the option to change the diff height.
