I'm running 6s with the punch control set to 100% and reduced the throttle curve. I've broken 5 rear diff pinions. I made sure they were shimmed properly each time I replaced it.

I now have the CEN diffs in there. I took it out for the first time a couple weeks ago and somehow managed to crack the rear bulkhead where the pinion comes out. I wasn't even driving it hard. The rear pinion completely tore through the bulkhead. Both gears were fine when I took it apart.

I got the bulkhead replaced and figured the damage was a fluke. Last Saturday, It was holding up great. I was driving fairly recklessly doing backflips off of jumps and had some bad landings that would've broke the stock pinion right away. At the end of the day, I did a standing backflip off a curb and heard something crack. After it landed, I heard the click from the rear diff. I'm pretty sure the pinion lost a tooth. I saw exactly what happened though. When I did the backflip, I saw the rear wheels hit the curb and that's when I heard the crack. I haven't torn it apart it to see the damage, but chances are the pinion broke a tooth.

Everytime I broke a stock one, It was from doing a backflip and landed hard. I always let off the throttle when i'm doing the backflips, but maybe i'm not letting off early enough.

The CEN gears seem to be significantly stronger, but not quite "bullet proof" yet. Then again, I am driving it harder than I probably should.

Hopefully HPI's new diff will be much better.
