Sand the rings with 600grit sandpaper... and use the diff screw and thrust bearing from a trf417. Cank it down as tight as you can. That's the most you can do though... you'll eventually snap the diff screw especially if you're running on high grip surfaces. Ran my kit thi way when the R first came out and i was too cheap to buy a new kit and wanted to wait for the gear diff case to come out as an option part. You'll miss the rip out of the corner though if you're running against others using the gear diff.

Make sure you use some shoe goo or runner cement to glue the rings to the diff out drives.

Helpful hint for the Tamiya Track. For a 5 minute race we have found the optimal final drive to be 3.85. The best spur/pinion combo for this is 80/54.

What is the part number for Tamiya 80/54 gear ?

There is none. Look aftermarket for 64 pitch gears in that size.

Also, there is no "GT4" class in TCS; it's the FF class. Additionally the 3.85 gear ratio was applied when the stock silver-can motor was being used. The recommend gear ratio now may be different with the use of brushless motors, and more importantly, the track you'll be driving at.

OIC, now I have to look for available aftermarket gears.

Finding the right gearing for the track would not be easy though.

Thanks EricP

Just done my homework and found there are several spur gears produced by Tamiya, as follows:

Standard Spur Gear
#51423 = 68T (48 Pitch for FF-03)
#54227 = 102T (64 Pitch for FF-03)

Alternative Spur Gear
#51548 = 66T (48 Pitch for TB-04)
#51356 = 64T (48 Pitch for TB-03)
#54055 = 96T (64 Pitch for TB-03)
#50978 = 96T/90T (64 Pitch for TB-Evo)

I don't know whether these alternative spur gears fit with FF-03 or not. Has anyone ever use any of the aforementioned alternative spur gears ??

Further, I also found several aftermarket gears (Spur & Pinion), i.e., RobinsonRacing, PrecisionRacing and KawadaModel. These 3 vendors produce various gear's model of 48Pitch & 64Pitch.

How is the comparison between these 3 vendors ? which one produced better gears in terms of material quality ?

Max gearing using tamiya spurs and pinions:
.06 module
64/29 = 5.74

.04 module
90/51 = 4.59

You'd need to go with aftetmarket spurs and pinions to hit 3.85

Thanks for sharing guys

I found that Tamiya produced 04 module, 06 module, 48 Pitch and 64 Pitch.

However, (having read forum/rookie-zone/34521-48-pitch-64-pitch.html), it seems that Tamiya's 04 module is not compatible with 64 Pitch, and 06 module is not compatible with 48 Pitch.

This is confusing for a beginner like me to learn the compatibility between each products.

04 module works fine with 64p... i run it all the time. Its not an ideal combo but it works fine.

Its a different story with 06 module as it doesn't mesh with 48pitch.

VooDooPh,

Thanks for your tips. It helps me a lot, and I still need to read a lot from this forum concerning the FDR, internal ratio, motor turn and other related tuning tips.

For anybody interested in a real nice FF03 with the hard-to-get Tamiya carbon fiber chassis ... I need to sell mine.
