Umm, I don’t know if this information is accurate, but I was browsing RCMiniRacer, and they have two Perfection 4.2 motors. One of them (the one that betty.k just posted) supposedly has lower torque, 35 newtons per meter (same torque as a 3.8). But the other one has higher torque at the same price, 39 newtons per meter.
