Hmmm...
 

Ok. I have a RC10B5M Champions Edition..comes with 4 and 3 ball diff.
I am thinking of changing to the New B6...but...
Are there any advantages?
I run the B5M with the 4 gear configuration.
If I went to a geared Diff rather than ball or swap to 3 gear and use either
the Ball diff or Gear diff would it make much difference?
Would it be better to get rid if the B5M and just get the newer model with the
3 gear laydown?

Lots of questions I know but thoughts please..:)

What surface do you race on?
