if there are omni wheels on the sides, why does the center wheel have to be dropped that much, i would go with 1/6 because the omni wheels will wear about the same.

this one looks much better than your first... i am making a few chassis which i will upload later... who knows, i might see some of these chassis out on the field for next year

1/8 is less than 1/6.

Wheel drops generally aren't picked because of tread wear.

If those are andymark wheels you actually have to drop the plaction wheel down 1/8 ish, because even though supposedly the wheels have the same diameter, they really do not.

Sucks if your plactions are not touching the ground.

Are the omnis necessary on this chassis? We have just about the same design with a very small drop in the middle with no omnis at all and it has to be one of the most smooth-driving chassis we have ever had!

Im just wondering.

I would change from four omni wheels to two omni wheels on the opposite corners with standard drive wheels in the other corners. With just two omni wheels in the oposit corners you will have btter traction and you will be able to turn easy. Or if you are droping the center wheels forget the omnis all together.

Won't the traction wheels in the opposite corners cause too much friction to turn assuming all wheels are on the same plane? The point of a rocker is to cause a wheel configuration that is shorter than it is wide. With omni's in opposite corners, you will not have this configuration. This could potentially prevent turning. Prototype it though.
