I've heard several people say that the Novak pinioned are the quietest.
That said, I've also made my Teknos quieter than most with the Tekno pinions simply by running the gear mesh mo tight. Due to the great tolerances and balance, I've been able to go tighter mesh (less chatter) with no binding than I can on several of my 2wd 10th scale vehicles. That in both an eb48 be sct410, though the same should apply here.

Give it a shot, make it as tight as you can without having a spot in the rotation with no play/chatter at all.
