Default Rudy Kouhoupt 5 Cylinder Air Radial

Here is a Youtube link to an air radial engine that I built three years ago. (I'm getting a kick out of this little Flip video camera that my wife gave me for Christmas although I'm supposed to be making videos of the grandchildren ) It was my first model engine and I believe it was the last published plan set oby Rudy Kouhoupt before he passed away. I modified the head design a bit to avoid the soldering in his original design so I could make the entire engine from white metal. It will idle with 3 psi of compressed air. - Terry

A Gismo ??? If it has a flywheel or spins and is made with small parts. I'll take one! If it makes noise, moves, or requires frequent oiling and dusting it's a better deal yet. It's especially right if its shiny and bright.

Any build photo's?

Thanks for showing your hard work, it is beautiful.

Is the mounting base cast iron or what keeps it from taking off?

Hi,
The air tubes are JB Welded into the head and the crankcase adapters. This was done in place during assembly. The head, air tube and adapter are now removable only as one piece. The base is a heavy chunk of carbon fiber laminate that I found at a scrap yard. I had saved it for many years for something special but decided to use it here. Here are the only build pictures I took:

I've seen this one (and the V-twin) in person. Terry does really really nice work. Thanks for posting that one.

Really a neat engine. Love the sound.
Are plans available for this engine?

Thanks Dave. Your engine are just beautiful. Neet looking mount also. Do you have a video of it running. I sure would like to see it if you do.

The only thing I found at village press was a 80 page spiralbound book for 14.95. Is that the book you are talking about and does it have a full set of plans in it?
