That's great news.
on the topic of gear boxes .. i'm wondering if any owners have a similar problem as mine does. i don't have any issues with slop on the diff case BUT where the gear box is exposed (small rectangular area) at the bottom of the chassis, mine is worn all the way through until a small hole appears (around 1mm by 2mm) exposing the internal gear!
i run on dirt track (some times abrasive, depending on weather).
The bottom chassis has normal wear, certainly nothing excessive.
did i win the short straw again?
