Looks great! Love it!

A few questions:
1) Why 4"x2" wheels? Could 4"x1" work as well?
2) (From a business point of view) Why would you say this chassis is "better" than 1114's KoS?
3) If you were to name 3 distinct features about your chassis, what would they be?

Overall, great design, great features, great everything!
