cause with the 4600 it has more torquo than the 5700.
They are really the same motor.
One just TRIES to make more power per volt it receives. That doesn't really make it faster. All that means is that the 5700kv will spin more RPM then the 4600Kv. Remember, that the 4600kv will stay cooler, have more torque and runtime. To gear up the 4600kv, is the same pretty much as the 5700kv. Try gearing your motor up. It will increase the temperatures, but it will give you less torque. Both of them can be way toned down with punch control. You can make the 5700kv just as mild as the 4600kv. That's one of the great MM features, take advantage of it. I love how people always assume that the higher Kv just means FASTER. Incase you guys didn't know the Vxl motor is 3500kv (very low). But guess what, it runs cool, and people can gear it to the moon. That's why it can hit the 70 mph. It's right there with the 5700kv. All you have to do is gear it up.
