Going To 32p (Mod .8) On My Rustler

[brijar]

Ok, so I'm tired of the wobbly spurs and would like to use a Jato spur gear on my Rustler. I just want to make sure all the things I think I know are correct.

• Firstly, that a 32p pinion gear will work with a mod .8 Jato spur gear and that that spur gear will mount right up to my Rustler's REVO spec slipper (standard XL-5 version slipper on an XL-1 truck).
• Secondly, that it's a good idea to go with this conversion. I will have fewer options as far as gearing goes, but the gears should be stronger and last longer.
• Thirdly, that I should get a 10t 32p pinion and a 58t mod .8 spur to replace my current 15t 48p pinion and 90t 48p spur, which seems to be a pretty happy gearing for my Mamba Max 5700 on 3s A123 and Stampede Talon tires.
• Lastly, where a good place to get the spur and pinion is? Don't really want to pay a ton in shipping, so I'm thinking I'll check my LHS, though I haven't been up there in forever. I have some 12t 32p pinions I had bought for my Villain IVX and my now sold E-Maxx, but I'm thinking they're too big for my gearing needs. Thoughts?

Thanks for any help!

When I had a problem with wobbly spurs on my Rustler it was because of a defect in the slipper. Never had a problem with the spurs themselves. You just want to make certain that the problem is with the spurs, or changing to 32p won't help.

I guess it could be a problem with the slipper. I was hoping that the 32p gears wouldn't care as much about a little wobble if they still wobble. The larger teeth should have a higher tolerance for what an acceptable spacing is, right?

I'd first check the slipper for wobble by rotating it without a spur installed. The defect on mine that I mentioned (and others have seen) was a bit of extra metal in the pin slot itself where the plate fits over the pin. I tiny bit of extra metal there will throw the whole slipper assembly off signficantly.

If your slipper has no wobble - then carefully installing the spur, tightening the screws together (not one all the way) should give you no wobble (unless the spur is warped to begin with).

Again, I never had a problem with a spur gear itself -just the slipper.
