Dear CD,

For Summer Project 3, I purchased some 6 inch, VEX OMNI and traction wheels. I added the wedgetop to the traction wheels (1-1/2 inch wide) and have found that the wheel diameters are different by a half inch or so. So where does this leave me? It seems like if I put these together in a 6WD configuration using a KIT chassis with pre-drilled holes that the OMNI wheels will not make significant contact to the ground (carpet). My options seem to be:

1) Don't use VEX OMNI and traction wheels together.

2) Re-drill the KOP chassis holes to raise the traction wheels center higher.

Is there another way? How have you solved this problem? Am I missing something here?
