On-road BL project

I used a MGT spur gear on a Revo slipper clutch unit for quite a while. If you have a 5mm drill bit, you can bore out 3 of the wholes (triangle pattern) on the slipper clutch plate and the spur gear is a nice tight fit - that doesn't stick out far.

Thanks guys. I have a place to start.

Batfish: Yeah, I figured the Jato used 32p teeth from parts in the stores. Not sure yet if I want to stick with that or go Mod1. I guess I'll have to pick up a Jato roller and go from there. I plan on coverting to single speed and use motor brake, so tranny work will be in order. While I'm at it, I'dd do any kind of drivetrain mods I can. To get better runtimes (and less current draw),, I was thinking of a slower motor, using 4s E-Molis and gearing it up, something like a XLBasic 2400?

MetalMan; The Mamba Max package does look like it would work, and relatively cheap too. Seeing the picture, those motors look to be an "S" can, is that right? With a kv of 4600, that's a 6 or 7 turn right? That's gonna suck quite a bit of current too I'm assuming. If I decide to do low cell counts, that will work fine. I'd like a bit more runtime though...

Sorry for all the newb-like questions. I've done two Revo conversions and both are relatively heavy trucks, have quite decent drivetrains, and have room for basically any reasonable amount of cells. The Jato is lighter and only 2wd, so probably has a not-so-robust drivetrain. So, I don't want to throw too much power into it and wreck everthing - then again, I DO want insane speeds (~50mph for me is insane) :)

Stock 2-speed with a xl4200 and 3s lipo is right around 50mph with a 21t 32p pinion. I can say that the Jato's drivetrain is pretty strong and not at all loose, but it is all plastic gears so you can only put so much torque through it before they start stripping.
It's also nice that the rear axle diff is a geared diff instead of a ball diff. Ball diffs have a harder time coping with large amounts of torque.
