Do you wanna Drift or race ??

19x2T is right in the core range of most drifters..(we are talking Brushed motors not brushles)
They have more Top end then most desire but still have the Torque needed for technical slides...

A 13T motor would be a poor choice for a drift motor as the torque curve would be too soft..
( as in the Torque Curve would start at around 3000rpm where as a 19X2T has a sharper Torque which means you can loose traction quicker without speed making drifts more controlable)

It would how ever make a good Street racer as long as you geared the TT-01 to take it..
