Has anyone managed to get the diffs on the sbv2 tight enough. There always a lot of slip.Previously melted lots of them I've mentioned this before to Dave Grabowski with no other suggestions than better diff grease. Someone suggested spring from a B4 , diameter to big. Horizon or whoever the importer is, sent me a new diff that they built and it was no better. Have now purchased the steel outdrives which has helped but I still cannot get them tight enough, nothing like say kyosho or the ones in B44. Any suggestion? Or anyone tried any alternatives.

And yes before anyone says it better driving might help. But, someone has to.
