You can find Ofna, Jammin, and HotBodies diffs pretty cheap on Ebay. They are all basically the same and work with the RCM output shafts. I know for the Jammin and HotBodies you can use the hardened steel internals which last a lot longer than the cheap cast pot metal stock ones. I use the hardened steel ones in all my diffs for my Jammin and Nexx8.
How do you like the "soltless motors" as they wrote it on the first teaser pics for these motors. Why do you have the silver arrow esc and not the cirtix 1/8 esc, should think they were made for each other no?
