Yeah but I think both of them suck for gouging early adopter customers to pay hard earned $$ to pay for their mistakes. If there is a performance improvement, sure I will be happy to pay. But when there are clear mistakes, they should provide the "fix" parts to customers on a case by case recall basis. Example: PN 94mm LCG motor mount. The part is awesome but hold down screw set up for the upright is a joke and well documented. They fixed it in next rev and expect everybody to pay another $40!!

Neither Atomic nor EGR have forums unfortunately


So I tried the Kyosho spur gear swap last night.

~~The good news is the Kyosho spur gear ID fits on the Atomic ball diff.
~~The bad news is the Atomic spur has bigger balls and holes.
~~Once everything is bolted up in the Atomic diff, there is too much of a gap to make up so the diff rings will meet the tiny diff balls used by Kyosho. My next solution that will likely work fine is to make a spacer to take up the difference. I am thinking of taking one of the Kyosho diff rings and gluing it to the back side of the Atomic diff ring to get the tolerance back "in the zone". I will report back on this as I test or if I resort to some other shimming technique.

I think the unfortunate part and the reason that the Atomic diff is so smooth is because of the bigger balls. Though the diff rings are better chromed material so there may be some adopted benefit. However the lighter spring tension range and adjustabillity may make this project worth it.
