I found that in the right hands and setup, while running 27t brushed motors another driver with a TC5 and me with a TC4 we were equals. Since then we have changed to the LRP x11 17.5 and are also running TC5's both of us have are now going faster, and I'm going faster then what my TC4 could with a 17.5. I don't even have my TC5 dialled yet and yet I'm already going nearly 2 seconds faster then what I was doing with my TC4 which was dialled.
The steering in the TC5 is far more surperior then what the TC4 is.
