Academy SB V2 PRO Motor question

[DrKnow65]

They have steel outdrives and you can use better 3/32" diff balls and losi spring. The slipper adjustment is critical to keep from smoking diffs. I don't really see how the diffs in the SB V2 are that much different from the common ball diffs, with the exception of smaller balls. I'm thinink that there may be a potential to machine back the ring lands on the steel outdrives to allow the use of 1/8" balls if I find I just can't keep the diffs togeather. That and breaking in the diffs gently.
