RE: The Wonderful World of Half-tracks!
I don't know which VS motors you are thinking about, but I got a couple of their 1/24 scale motors a few months ago. The ones I have are made with sprockets that are pressed on to a shaft similar to an allen wrench. They are not attached with screws or adhesive. They pulled off with a bit of effort, but came off without damage. Hope this helps in your case ............
