    Anyone turn a castle 2028 higher than 30k rpm?

    Just thinking out loud. I know their stuff is higher quality than these other big motors on the market. Anyone turn one over 30k rpm for short blasts?

    Some have. A key to higher rpm is to replace the bearings, they are apparently sourced from a skateboard supplier(?) but are good enough for 30,000 rpm. Boca would be my choice. The next failure point is usually the magnets coming loose, I haven't opened up a 2028 too see how well they are glued/wrapped.
