CVD's falling apart - too much power? Stockers hold up better?

[JThiessen]

I have a set of the steel MIP CVD's on my Revo conversion (currently running a HV-4.5). While bashing today, somehow the left rear came out of the cup at the diff. I couldnt simulate this by move the suspension, so it must have been one of the hard tumbles I took that must have flexed the A-arm back/forward.

I'm thinking of going back to the stock Revo drive shafts. My first question, is do they work with RPM A-Arms? Second, is there any difference between the original 2.5 shafts and the new 3.3 shafts? My guess is no, but I thought I'd ask.

With a fresh 4600 A123 batteries, this thing is almost uncontrollable. I also bent the CVD on the other side, and ripped the tire glue off three of the tires (they held up for 2 years now). How sweet it is!!
