You going ahead n making one?
Joe,
I may have to go back to the drawing board if I can't source these wheels in UK, but yes I am going ahead with the product.
I have all the rest of the parts required to build my first 3 prototypes/demonstration models, so just to get them out there I may have to bite the bullet and purchase the wheels for these 3 from US, the wheels are reasonable priced, but the postage and any customs fees are the killer taking the cost per wheel up to around £60.
