Does your local club racing allow aftermarket on your F1?
If so.. Start looking in to 3Racing. Cheaper on price.. not on quality.
I run a complete 3Racing / F104pro. I've converted to 48p gearing and run a Kimbrough Spur with ACER 1/8th ceramic bearings, Associated diff grease, and stock Tamiya diff. rings. Most unbelievable smooth diff.
Not because of the brand of bearings I use, just simply the Tamiya or 3Racing simple direct-drive diff assembly is a great diff. all around. Easy to build and maintain.
BTW.. Fact: 90% of the bearings on our markets are purchased in bulk from a specific manufacturer. Then independent companies make their own labels and packages then sell them to you threw distributors. I know, my friend owns a VERY popular R/C bearing company that most all of you on here know, for 20+years. .
(annonymous) Not ACER either.
Moral of the story, is buy any good set of ceramic bearings from your local Hobby Shop or Online Dealer and your F1 will have a lot better diff. performance.
P.S.. Don't be surprised if you see a compatible aftermarket Gear Diff. released soon for the Tamiya F1!
