Yes! I did a bunch of gear mesh calculations, ordered up a couple of gears, and it works.
I shot for a little higher (numerically) FDR of 4.37 and it meshes perfectly, so my calculations were sound and these other gearing combos should work.
All of the following numbers pertain to 64p gears (use the "hockey puck" spur adapter that came with the kit).
FDR 4.37:
- 74t spur, 44t pinion, motor mount position B.
- I got these from superiorhobbies.com. 44t pinion=RRP4344, 74t spur=XENG640074
- tested and meshes perfectly
FDR 4.28:
- 74t spur, 45t pinion, motor mount position C.
FDR 4.25:
- 72t spur, 44t pinion, motor mount position A.
- 72t spur may be hard to find, but PRS just started making them.
FDR 4.47:
- 74t spur, 43t pinion, motor mount position A/B.
- 3racing mount A/B position will probably work perfectly with this combo
FDR 4.58:
- 74t spur, 42t pinion, motor mount position A.
It wouldn't hurt to use the 3racing motor mount with any of these combos as it gives you finer mesh adjustment.

Hello,
I just got my TB02R that I am going to setup for T/A. I believe I have the 3Racing motor mount. The top holes are almost one big slot. The question that I have what end does the "A" location start?
Thank you for the research on the gears ratios!

) is the hole on the bottom closest to the spur and its corresponding hole diagonally.

I just purchased the blue conversion kit and was wondering about the motor mount - can I use this mount and the original plastic brace in the rear or will I need to purchase a different style of motor mount (one without the voids)? The original mount is solid - this one is like the TB-02R mount. Can I use the spur gear mount with the original rear plastic brace? What additional parts are needed for the front one way? I tried to leave an image of the set, but I can't. Just look at Tamiya USA - TB Blue Comversion kit.

I know this isn't really the place to put this, but this is where the TB02 guys are and our numbers aren't huge...
I am planning on selling two identical TB02 rollers. They are very clean -- maybe a half-dozen race days on each on smooth asphalt -- never bashed on the street.
Each has the following mods:
- Tech Racing spool in the front (aluminum center, steel outdrives)
- 3racing blue aluminum motor mount
- Yeah Racing carbon fiber rear top plate
Bone stock other than that and in great working order. These were run with silver can or 21.5 so they haven't been worked very hard.
I'll take some pics ASAP and post them in a proper for sale thread, which I'll link to here.
