hi, i just found that the carbon brushes on my x-speed ran out, so i put the brushes from the stock motor on the x-speed, then i noticed my car run really slow, just wondered why and i open another stock motor and check if the bruehes are same as the x-speed ones, i found that they dun have noticable difference, same width and same size, but it says WA-18 on the x-speed and WA-22 on the stock motor, anyone knows what those mean?

I am curious myself...I never noticed those numbers you mentioned.....maybe they refer to the hardness of the brush, or something to do with how much current they can cope with?

may be hardness.
What I know is PN brushes do a good job for me.
at least, higher silver for more power. but also running out faster.
