TZ (T=Torque)/ RZ(R=rpm) are the same motor one with standup brushes, the other one with laydown brushes. Laydown brushes are a nice way to legally increase timing of a stock endbell (fixed 24 degrees).
The point is that with big turn engines (>20 turns), rpms is low but torque is massive. By adding more timing you get more rpm, less torque, less efficiency in short an engine that is more homogeneous.
In any case at the end of the day you won't see much difference except in a straight line...

I already have a super modifed 11t which i find great, but I notice it take a second or 2 to get really going, it builds up speed over about 5-10 meters. Id like another one, but id like something with a bit more punch instead of speed!!
