The wheels have arrived but TBH, now they are on there, I am not really happy with them so I may end up changing these. Anyway, drilled some grub holes into the hub they have, plopped them on and although the controls are all a bit back to front, it is now moving...



...briefly. I am possibly going to end up building some custom HDPE hubs for these, remove the hubs on the wheels that are there and then bolt them onto the hub.
