The Smallest RC Engine In The WORLD!

I met Ronald Valentine recently and he says he makes the smallest combustion engines in the world. I am not the expert here, but I must say he holds the title so far as I can see. His smallest engine is less than the size of an American quarter coin and I am really impressed. You can visit Ronald’s website and make your own decision, but from my view he has made some really fine engines. To view the smallest RC engines in the world then visit Ronald’s website here.
