Hey guys just some feedback on these sealed diffs

I bought them for my Slash which already has a FLM Transmission case.

Initial impressions, No instructions, AGAIN!

Assembled, fitted, grindy grindy, the pack came with socket head bolts, not counter sunk ones and being a 2.5mm thread not ones I had readily available. Clean up the mess, reassemble etc

Spent 2 hrs shimming up making sure I was bind free etc, reassembled, hooked in a 17.5 on 2s lipo and there is a distinct whine coming from the diff area especially when rolling off power. Seems almost as if there is a pitch difference between the FLM diff and the Slash idler.

So, in conclusion? Don't bother with it.

I have it now, but in hindsight it's too little gain for too much mucking around.

Buying a spare stock diff (complete) and will slap that in when (not if) this thing fails, being in Australia, postage costs make the FLM Warranty nigh on worthless to me.
