I experienced different noises for the mesh mugen MBX5T 46T spur/pinion, depending the steel of the pinions. RCM pinions are quite good for noise but they use themselves a lot :( Novak pinions work great, but are a little bit long. Robinson Racing pinions do a strange noise with mugen spur. But in my RR pinions, I found one of different color, and it works surprisly perfect, totaly no noise like the Novak with the pro of a small pinion, and it don't use itself at all :D. I will keep it !
