"How To Properly Build And Break In a Ball Differential and Slipper Clutch"

When adjusting the slipper in say a larger vehicle like the sc10, how much should the front lift? I'm having a hard time gauging if the slipper is too tight or loose watching the front end rise.

So, does the slipper bench test not really work for short course trucks?

Awesome tutorial. I've been using gear diffs for a few years and this week will be my first experience with a ball diff. This video has explained quite a bit and now I feel more confident about racing with a ball diff.
Keep up the good work!

Do you guys set your slipper the same way between buggy, ST, and SC? Seems like there should be a difference because of different lengths and weights of the vehicles.
I've always set my slipper by "feel." I'd set it it flush then drive around the track and adjust from there.

Not the best way to explain it but you should get my point.

I use it for both buggy and SCT. I feel that it's gets you pretty close to where you need it be. Some on track final adjusting may be needed. I say it works for both buggy and SCT because it's sort of self adjusting for the vehicle, a buggy being shorter and lighter needs a looser slipper. The slipper setting on a SCT is going much tighter to get the same 2 inches of lift than it will be for a buggy. Both lift the same but the slippers are set different. I adjust my slipper VERY little if at all from the 2 inch bench method on my med grip track.

Great video. Thanks for doing this. Glad it's a sticky.
By the way, sanded my slipper pads and they turned the color of the 500 grit sandpaper. Motor spray didn't seem to do a thing. Problem?

I haven't had that problem before, as you saw in the video mine came clean...what type of sandpaper and what type of slipper pads where you using???
Just a thought, you could always scrape them with an X-acto knife...

They were AE slipper pads which I had to run for a 17.5 non-ramping class because Kyosho doesn't make a spur gear smaller than 76t. I borrowed the sandpaper from the guy next to me so I don't remember what brand it was. I usually use 3M.
Regardless, I'll be switching back to 13.5 and the Kyosho pads now so I should be good-to-go.
Thanks for your help.

An FYI on thrust balls, I'm sure B-Fast makes them but I've seen guys use the carbide DIFF balls from the RC18 vehicles as thrust balls in the 1/10th AE stuff.
