[Aren_Hill]

each module has its own cim/dewalt 3 speed combo driving it. and the vandoor motor to rotate them all i chose this mainly because of only having to use 1 motor and the fact we have 4 2"wide wheels in contact with the ground.
if i link all the modules together i lose the ability to turn the frame itself yes i could do two and two but the drive systems been designed to handle 1 cim per 4"diameter wheel.
the dewalt gives us 3,7,12 fps speeds
