i've been using the slapmaster tool for drilling holes in my brushes for my 19t checkpoint money motor, and it has really made a difference, what it apparently does is increase the RPM but only lowers the torque buy a small amount. I've found that it has worked on my 12th scale, so i would recommend it anyone.
