Ultracast has been providing replacement wheels for quite some time. The latest offerings are all designed for the Mosquito. What sets Ultracast wheels apart from the rest of the replacement wheels is the bulge. They are realistically bulged and will add an appropriate weight to your model.
Perfectly molded in light caramel color, there are two wheels per set that are molded with unique treads. The pour blocks are small and placed in an inconspicuous place, the flat spot. Adding them to your Airfix, Monogram or Tamiya model is very easy. Remove the wheel from the block, clean up with a sanding stick, then paint and add.
Also when you order from Ultracast directly you will have to add $9.95 CDN for shipping and handling world wide.
