Roc412 gearing ?

[OH91awd]

ordered my roc412 3100kv motor for my scx10 g6 this week and was wondering what gearing I should run on it. It has the stock 87t spur gear. Just wanted to see what anyone might suggest for gearing. It does have the stock 1.9s on it.

I would start out with 87/18 and then see how it runs and check the temperature.

You might be better off switching to 32P gears. My 48p spur didn't last very long with the Roc412. For 32p I would start out with 56/12.

I've seen a few people run 48p gears without a problem.. If it doesn't work I can always switch

Ive found 11-13 pinion gear with a 56 spur to work well. 48 pitch will not live ive already toasted 32p steel gears.

Oh wow lol. Where can I find a good 32p setup for the scx10 trans?

With 32P gears, plastic will probably be strong enough. You can use the
DuraTrax 32P 56T Nitro Evader BX spur. The part# is DTXC9397.

If you want steel, then the RPP Robinson Racing 32P Slipper Kit Steel Slipper(56T) Part# RRP7856 and the Beefy Top Shaft from Supershafty will work.

I also hope you have steel internals in the trans, otherwise they should be next on your list.

planned on upgrading the trans next as well

You will probably be replacing drive shafts too. I tried the no twist mod on the WB8's but with the ROC412 they snapped in two instead of twisting.

I would add a set of MIP's to the parts list.

I was looking into the rc4wd punisher shafts as well.

im on 1.9s and have the same gearing on a axial 27t motor. may see how that gearing treats me.
