Update on my ERBE.
The ERBE is holding up very well to bashing and racing, I managed to break a rear suspension arm landing a really big jump and that is about the only thing I have broken recently. I noticed that my Summit shafts were getting quite a bit of slop due to wear. I have been using my ERBE every day since I made all these modifications so I guess this was to be expected. I had a full set of spare Summit shafts so I installed new ones all around, changed a few ball ends on the turnbuckles and pushrods as a precaution and will put new ball ends on the shocks and the ERBE should be ready for the final race of the season this Sunday. My aluminum slipper did so well at protecting my drive train that when the new Summit shafts I just installed wear out, I will put back the stock shafts and see how well they hold up. I am pretty sure that they will do fine with the help of that slipper but we'll see. I haven't done any changes to my connectors yet but I'm thinking about it

Maybe I will find some time to do it before Sunday.
I haven't done any checking of the 8th scale diffs but they are so smooth that I don't see the need to take them out to check them. I have ordered some
Losi heavy duty diff cups to install when the snow comes and I disassemble the whole truck for an overhaul.
I am also working on a new 8th scale center diff made with a Losi XXL diff and a different Traxxas gear with a different and easier way to secure the gear to the diff cap.
