I don't think a aluminum cup is needed, i think what is happening, is when MC, does a small modification, like trimming or something ( don't get upset on me), this tends to weaken the part, I have been running my same original 1st prototype 1/8 hyper CD, and havn't had a single issue at all, not even a small one, I inspected the whole thing this weekend when I switched out the 30k for 50k fluid, and saw no visual wear in the cup, gears, modded shafts or reng gear, the bearings all rolled freely as well.
