The first being, I keep breaking the rims right around the hex drive. Is this common for a beginner? Today it actually cracked and before I noticed I had rounded the hex drive.

The second thing I had an issue with was the gears. It just wasn't getting power down and it felt like the gears had stripped. So tonight I pulled it apart and the gears seam fine. Is there anything else I should be looking at? How do I check the diff is working?
I've ordered the harder gears to put in while its apart. I can't find a gear oil diff anywhere, so I am going to try the ear plug method. Did someone say you could use tyre inserts as well?
another way of tightening up the diff is with some anti-wear (silver) grease and a couple of shims..

take the diff apart and use 1 shim on the backside of both bevel (big) gears, then coat all the gears with the anti-wear grease, then put it back together...

the anti-wear grease is super thick and stick and the shims will make the gears press together tighter - all resulting in a tighter feeling diff..

on one of my diffs, I used 2 shims under each bevel gear and the grease, and might is super tight, almost like a spool

I've use the anti-wear grease and a diff tighten'er before on a TT01 diff that was used in a 24 hour endure.. the grease make 6ish hours of constant running (about 1/4 of the race) before the diff loosened up.. so this does work as an option
