Quoting Stephen Barnes
About time Tiny Turbos made a comeback I think. They were cheap and adaptable. I made dozens of variants of them, no instructions needed. Speed Championz took over I guess.
Thank you for your comment. Glad you like my work. But I do not think it is fair to compare the two series. Tiny Turbos are small, and Speep Champions are Minifig scale. Both are great series. Unfortunately I was in my Dark Ages when Tiny Turbos were on the market.
