Anyone converted the RB5 to gear diff?
 

Have anyone converted their Ultima RB5 from ball diff to gear diff using the Ultima SC parts?

Thought I might try it this summer. I'm not that good with ball diffs :D

Hey!
Ultima got one of the best balldiffs out there and if you sand the rings, use ceramic diffballs and use a lot of Schumacher diff lube you will be all set. smoooth:thumbsup:

Looked at doing this to try it but I really see no point ... I rebuilt the diff in the RB5 recently (ok about June last year, stock Kysoho plates with no sanding or such like, MicroTech supplied ceramic diff & thrust balls) and it's still silky smooth!!

So i'm buying my stuff for the summer season and thinking about my diffs.
I've got 4 pretty fresh diffs. (maybe 4-5 race days on them) and thinking about 1 rebuild for 2 for this summer.
Which rings and balls to get? And whats grease?
I looked at the B-fast, but that would cost like 50usd for me.
Abit too much.

I always use Kyosho diff rings and either Kyosho or MicroTech racing suplied carbide diff balls. As for grease I use the AE greases. For the thrust race I use the standard Kyosho BRG100 pack too.

Perfect diff everytime :)

Kyosho Ball Diff Grease.

Its super good

Will order up some to try then Neil, if it's as good as the rest of Kyosho's stuff then I'll prepare to be mightily impressed"
