It's one thing to turn the wheels on a stationary vehicle, a Futaba S3003 can do that. The hard part is holding them in the turned position while flying around a corner at 40mph. That is where you need the torque.

I think some people don't understand that. They use a low-end servo and test it with the vehicle sitting in front of them and say, "See, this turns the wheels fine." without realizing understanding how much more work it is to do that while cornering at speed.
