One of the smallest model diesel engines in the world. Beautiful designed engine in superb condition with excellent compression. We are now in Perry, Georgia, where we met this wonderful man, his name – Ronald Valentine! We do not blame you if you have never heard of this man, but is about time! He is the creator of many small engines which are so tiny that it makes it hard to believe that they actually work! Ronald said that he first started off with this to see how small a combustion engines can be, and it turned out, it could be as small as a QUARTER! Ronald has been doing this for 30 years so far, firstly starting in Germany, Stuttgart where he went to University! A particular engine caught our eyes, the NANO-B, which is Smallest Rc Engine In the World .
