How can you make turning smoother?

You need to go back and read Jason's post more carefully:

this reduces the "normal force" (hey, physics in action) on the front and rear wheels

Dropping the center wheels has exactly the effect described above by Jason, and this is the main reason why dropping the center wheels slightly makes the robot easier to turn.

I learned of centripetal force last year and asked my mentor who also happens to be my A.P. Physics teacher is this what caused a dropped 6wd to turn smoothly. He said yes.
Study centripetal force and you'll know what im talking about.

Could you please politely ask him to send me a PM?
