We used the AM14U3 KoP chassis with 12.7:1 2 CIM gearboxes. For wheels, we ended up getting tires from Princess Auto (Canadian Harbour Freight). We 3d printed a set of 2 piece inner wheels that the inner tube sat on. We then used aluminum plates that sandwiched the tire together after we had problems with breakages on the lamination lines of the 3d printed parts after pressurizing the tires (think of a beadlock tire/wheel). It probably would have been easier to cut down the stems on the steel rims that came with the wheels and then drill a bolt pattern to hold on the hex hubs and pulleys.
