1527 wouldnt kill the diffs any more than a 1521. Think of it like this. The diffs are obliterated and dogbones sheared when you try and pump 2kw through to the wheels from a stand still. Using a 1521 to hit it with 3kw or a 1527 to hit it with 4kw wont make any difference.

I run a 12XL on 6s lipo and the diff pinions and dogbones shear if I'm not gentle with the throttle, I don't know how anyones truck can survive with a neu! They seriously need to beef up the drivetrain on that thing if you want to run brushless. I think revo style driveshafts would do the trick, the torsional flex stops you drop shredding diffs and sheering those damn dogbones!
