Aluminium diff case and diff cup
I am using the [url=http://www.teamstrc.com/index.php?route=product/product&path=53_39&product_id=207]ST Racing diff case #ST5380B[/url] and the [url=http://www.hot-racing.com/index.cgi?partnumber=RVO11C01;c=431]Hot Racing diff cup #RVO11C01[/url] on my eSlay-Revo build.
They were fairly pricey to purchase; but these were bought at the time where I just seemed to strip my diff gears on a regular bases with my eRevo...at the time I rebuilt my eRevo I was in search of a bullet proof diff build but ended up doing the Losi mod instead.
I knew they wouldn't go to waste as I had the intention of building me eSlay-Revo for some time ;).
Here is the St racing diff case.
Here is the Hot Racing diff cup.
My first impression of the ST Racing diff case is that it is well machined and is a very nice snug fit in the bulkhead...after my experience with the Losi diff aluminium diff case I am confident that this will improve the life of my diff on this build :).
The Hot Racing diff cup is very solid and a nice fit inside the diff case.
Hot Racing diff cup I-Bar mod
The I-Bar is not a direct fit in the diff cup and required a slight mod to fit. I rounded off the corners on a belt sander as seen below. That is a comparison of a stock I-Bar to the one that has been modded.
As you can see it has been rounded quite significantly...you could probably achieve the same result with a grinder or dremel. It didn't take me long to do both; roughly 5 minutes or so ;).
The I-Bar fits in the diff cup nice and snug...with the spider gears in place it seems to be very solid and strong :thumbup:.
