Here we have some more Ronald Valentine diesels. The are also sometimes referred to as Rasant - Fast and Furious.
This is one of the prototypes of the 0.098 cc series. It is similar in appearance to the Super Bee and the Mini Bee.

Ronald produced a "Plexiglass" version for exhibition. He also ran it!. I wouldn't dare.
It is a little difficult to photograph to best advantage.

We are in contact by email and phone but distance prevents meeting. I have met quite a few engine builders over the years but no one can match the speed and accuracy of Ronald productions. Believe me, just when you think he has reached a model engine engineering limit - he surpasses it!!
When you see the Nano Bee in the below video - the smallest diesel in the world! - after this he went on to produce a vertical twin Nano Bee, then (what I thought was impossible!) a flat twin Nano Bee - I gave up thinking there was a limit!
