IMO, the aluminium seems to develop a little play after about 4-6 months of use. The blades seem to be harder then the aluminium. Don't know what material the blades are made from, maybe it's "delrin"
. I've had the delrin in since January, and with regard to wear; if it's not better then, it's at least as good as aluminium. I would imagine its lighter and I also think it makes the diff smoother as well.
Has anyone had trouble with wear on the aluminium centre pulleys? I'm assuming that this wear is coming from belt skip/wrap around the pulley because of the size and material of the pulley. I had heard that Tamiya went from a 15t to a 17t pulley to stop there excessive wear they were getting, but don't know for sure. I've just stuck in some 3Racing centre pulleys (and new belts) to see if it actually works/fixes it...
