tc3 spur/pinion combo
I just started running vta a couple weeks ago with a used tc3 setup. The guys in my class say that a 4.80 fdr is perfect for our track. What's my best option for 48p pinion & spur combo that doesn't require any chassis grinding or cam grinding? Thanks for the help in advance!

48 pitch: 72/37=4.86, 69/36=4.79.

Thanks for the quick reply Buckaroo but I don't think it completely answered my question. Based on the information that I've read on the tc3, the 36 & 37 pinion will both require chassis mods to fit. Do you happen to know the largest pinion that I can run without mods? Will 66/34 work without mods?

Because the diameter of the gears really doesn't change with respect to pitch, you will have to grind out the webbing under the pinion gear on the TC3 to arrive at you desired ratio. I know you may not like it, but I have 3 of them and its the only way to get to that ratio.
As to the 66/34, I don't know, never tried a spur that small in the TC3!
Only the dremel solves the clearance issue! Luckily, not much really needs to be removed. Work slowly, and be sure to take just a LITTLE extra to compensate for a little flex in the chassis.

Thanks for the responses guys! The guy that I bought it from included some 64p stuff but no combination gets me any closer to 4.80 than the 48p parts. Guess I'll head to the lhs and pick up a selection of pinions & spurs and then break out the dremel to get them to fit.

Robinson makes pinions in 70, 66, 60, 55, 52, and even 49T. One of these should get you to 4.8 FDR. To get an approx. 4.2FDR (for 21.5 motors) I usually use 60/35. 60/31 * 2.5 = 4.83 FDR.

In case you decide to tackle the mod I dug this up for you. It's really pretty easy.
