BeachBuggyPhil: I don't know, I'll look into it. EDIT: an AE driver and friend just responded to my text; No the SC10 4x4 slipper parts/assembly will not fit on an SC10/B4/X-6. The parts look the same but they're scaled a bit bigger.
ianjoyner: I rarely replace the pads - again, only really when they get pitted or massively scratched from some small piece of debris. I do clean the pads with my hobby knife from fairly frequently - once ever two or three races, pretty much whenever I have reason to take the slipper apart. I do that by putting the pad on a hard flat surface and scraping it sideways with the hobby knife blade, scraping off the glazed surface and revealing new pad beneath. When I do finally replace the pads, I replace the slipper plates as well.
I use the "hold the rear tires and punch it!" method of setting my slipper before each race: put the radio on the left tire, hold the right tire, and give it a burst of full throttle. Assuming everything's working correctly (and you're not eating your diff) the slipper will slip as the front end rises off the bench slightly, and you adjust from there.
Well, the first time after cleaning the slipper pads, or when I've just put in new pads and plates, I find I have to essentially heat-cycle them or I'll get some slipper "fade" through the next run, while the pads seat themselves. It's kind of like breaking in a diff to me. Essentially what I do is leave the slipper on the loose side, hold the rear tires, and give the car 5 to 10 seconds of throttle. Make sure the outside slipper plate gets decently hot, that's the whole point. Give it a few seconds and then tighten/adjust the slipper to where you want it for the upcoming run.
I've linked it in another thread recently, but I can't stress enough: the third page of
this document is my EXACT process before each practice, qualifying, and main race.
