Yes, they increased the root dimension on the later ttech cars, which led to better reliability. Material, root dimension and how the gears are shimmed are the factors to determine reliability.
I'm not saying the Awesomatix will encounter the same problem, i'm just saying that sometimes a crown and pinion transmission layout
can be tempermental.
