| Give the builder credit, but certainly not the first. Several (10?) ago there was a duo in MO, that built a couple of 5 cyl radial engines that at least used VW pistons with the rest of the engine (probably much like this one) being custom machined. Had ugly square heads and just didn't look right. I think it put out 50 hp? Never really made it into development. There may have been a 3 cyl as well? Still, the VW is a remarkable engine, I love 1/2 VW flight stuff. Hope to one day own a 1/2 VW airplane. |

| It's been years since I read it, but the book "Small Wonder" described early VW engine prototypes and one of them was a radial, maybe even a diesel. |

sure 'nuff just finished (re)reading SW and Dr. P. at one point was thinking radial. Again, give the builder(s) noted above of having some skills, to take a blank piece of alloy and going from there. Radial engines (VW based or not) are pretty cool, but an old rotary aircraft engine that's just plain crazy. |

Maybe a dumb question, but how do they keep everything lubricated? How does the whole oil thing work in a radial without pooling in the lower cylinders? Oil pump? Oil sump I can't see? An inquiring mind wants to know.

dry sump. You are correct sitting, oil will collect in the bottom cylinders, but cavenged back into the system. However, if you (have the $) are flying - nothing beats the rumble of a radial. every time a Stearman flies into the local airport - I know instantly. Just look up and watch that majestic beast go by. |

We often get warbirds flying overhead from Van Nuys, Santa Paula, or Camarillo. Love that rumble! My dad flew Corsairs in WWI and I see the thrill that power gives you! |

Raw horsepower..

Has a relatively short life cycle and use oil and fuel like its going out of style...but when you needed 3000hp you had 3000hp.. |

Thank you and yes, love the sound of a radial.

B-25. Loudest damn prop plane in the sky and only 2 engines. You KNOW when one of those birds is flying nearby.  |

Emissions weren't so stringent and oil was cheap  they used almost as much as a 2-stroke. "it's when they stop leaking you have to worry"

I was at a classic Air show about 7 years ago. Amazing watching and hearing all the different war planes flying over.
Also just at the National Air Force Museum, some of those planes are still leaking oil and they have been sitting for years.

I've seen a lot of radial engine museum planes with coffee cans hanging by wires under the engines to catch the drippings. For some reason the inline engines don't need these. |
