I believe i pulled off a first, I broke an RC-Monster diff pinion

[RC-Monster Mike]

The v1 still works fine - just a PITA to modify the pinions, which is why the V2 is replacing it. If you haven't used your V1, you can swap it out no problem, but lets not assume that it will fail - with one failure in 80+ diffs out there, the failure rate is pretty low.

I've not put my V1 in the revo yet, i want to give a test to my stock revo diff before to put your diff in it. My V1 is sit on my workbench for now, but i'am not certain if i'll send it back to you to exchange for the V2 case and pinion or pay for another set of V2 case and pinion and keep it as a spare in my tool box.
Like that i'll can run the V1, if he broke, i'll have the V2 in hand to replace quickly, and if the V1 hold well, the V2 will stay in my toll box, maybe for a futur project

So keep us inform when the V2 will be available, and i'll e-mail you to order a set as soon as it will be available, and please Mike, if you can make somes buggy ratio at first, this is this one i'll need.

Than you Mike to take care of us, all guys here appreciated your work
