I looked into the Robinson Racing slipper plate. There is replacement pads and bearings available. I also found out from Robinson Racing that if you get there slipper assembly, you will need to get their spur gear for the motor. They said that the OEM one will eventually shred due to the difference in hardness.
I liked the Hot racing a little better, because it allows the use of the Traxxas nylon pinion gear, which is used as a mechanical fuse for the drive system.
I think it was Wildman that took a Traxxas break pad and modified it for use with the Hot Racing slipper plates. I liked his idea, but modified it further by taking away the excess pad. The reason? I did it to not allow the excess part of the pad to eventually come in contact with the center part of the slipper assembly base plate as the slipper plate pad wore. This would cause the slipper system to continuously to slip. To cut the center out of the pad I used an Electricians' Stepper Drill Bit.
I did order a Hot Racing slipper plates, but wanted to see if Wildmans' (I think it was Wildman) idea would work with Traxxas parts. It does, and works well if anyone out there in RC Land wants to give it a try. The advantage to using the Hot Racing assembly is that you have 12 contact points as to the Traxxas 6 which will provide twice the sheer strength. Anyway, here are some pictures...hope you all like.
