Any Q's about this kit....? (Besides when it will be in stores)
I have been running mine for a few weeks on an outdoor track with a bumpy, fluffy-to-sometimes-hard-packed, red clay surface. The updated/revised diff is holding up really well; staying 'smoother' longer, as are the new gears in the tranny. All of the new parts are very durable, too, as I have yet to break ANYTHING at all.
