Agree. A 28 x 28 6wheel WCD drop centre wheel is basically two wide configuration 28 x 14 (width x length) mate together. From my understanding any 6 wheel drive wider than a square should not have a drop centre. The AM14U(kit chassis) does not drop the centre wheel when configured to wide. If the square prototype is successful, I'll likely build at least one more version, most likely long, for the drive team to try.
