[George16]

I have Mugen, Kyosho, Ofna, Hot Bodies, Savage cups in my parts bin. The savage also uses the same bearing (8x16x5mm) like the aforementioned ones. Just remember that the Ofna ravager, mutilator uses paper gaskets while the Hyper 7 uses an o-ring between the cup and ring gear.

I think I still have measurements of everything I mentioned somewhere in my laptop.
