sorry for the Big Rock prefix, couldn't post without selecting something

I need some advice.
In short, wanted a Nero a bought a nice used one with diff brain about a year and a half ago, ran it for a few times, what a beast on 6S, a bit much for my type of general bashing actually ?
It ended up on the shelf due to a bunch of factors, parts i.e

Now I started to go through it, the beast thing makes more sense now, 17t pinion and locked center diff. Diff brain card seem to work just fine but had a buzzing sound from the locked centerdiff and the front diff does not lock up, the only thing that works right now is the rear, locks and unlocks.

Took the front diff out, all nice except for a dead and stuck servo.Center diff, a bit worn pins and the plastic has worn againt the case, servos not dead but doesn't work and can be moved back and forth with ease.

Now for the advice, should I repair it or remove the diff brain and servos altogether, is it worth the eventual trouble of keeping the diff brain system ?

That's a nice Nero u got there!
I think it's down to personal preference, obviously the v4 rigs have no diff brain and drive just fine, on my BR the rear went out and I just replaced the diff servo £30 gbp, Ebay, it was because I wasnt changing the modes at a crawl and stripped it out, imo it's a nice thing to have,something different and keeps it original,if yr not bothered about any of that spend the money on upgrades and send it as it is??

I say keep the diff brain and center lock mechanism/servo. That's what I did with my newly built Nero HD, cause it's the only one I ever lock/unlock. Never really locked the front or rear diffs in my Big Rock, so I deleted them when I built the Nero. Plus you end up with two spare servos and lock mechanisms.

I say keep it. keeps the value up there if you decide to ever sell and I always enjoyed that part when I owned mine.

I agree with keeping it ?, I’m in the process of doing maintenance on all three diffs (whole rig actually) and as much of a PITA it is to work on the reward is having something unique. I’ve had mine 4 years an it still impresses me every time I run it. Who knows, maybe it will be a collectors item someday, or it could just end up a obscure obsolete dust collector. How is yours going?

Wether it becomes a valuable collectable or not isn't too important to me, but I'm glad I have two of them.
