Hi Sam,

Thanks for your comments. The wheels great for the surfaces usually used in robot combat (steel, wood etc.). I will be using these wheels again in my next featherweight which I am designing now.

These wheels specifically are 86mm outer diameter x 50mm width. There are many other options (both diameter and width) on either Banggood/ Aliexpress or ebay directly from China (Link to the ones I use listed below):

Similar wheels have been used before in featherweights to great affect on both shrapnel and the latest version of Get Shrekt.

There is an option for either the serrated or slick tyre options. I have both, but so far haven't used the slicks yet as in the next event (whenever it will be), I will be using new drive speed controllers and don't want to make too many changes at once in case of an issue.

I did have to do a lot to them to suit my needs as they are quite heavy due to the amount of rubber. On FeatherDozer, the width is reduced to 45mm (still very wide) and bored out to fit the axle-to-wheel interface. Before an event I usually cover the wheels in gaffer tape to help clean the tyre surface before it is needed.
