I just picked up this Offy Model. I have the plans from Ron for the one he built. Did he make these castings and have them available at one time? Did anyone else cast these Offy’s? I plan to disassemble this engine, check dimensions and tolerances and try to get it to run!

Here is also a v8 model…possibly a Profi? Any info is greatly appreciated.

Thanks

Wow, that is quite a find. The Offy really looks nice. If you have Ron's plans you will see that he did not use castings but machined from the solid. Good luck getting her to run, I want to see it!
The Offy is a Gem! I bought these 2, a Jemma 7 cyl radial, and a 2cyl aero engine. Gave the 7 cyl radial to my dad for Xmas, made a nice addition to his 1/4 scale Merlin!
Thank you for the help

Did you happen to snap some pics of the Jemma radial before your nice gift? I remember it from SIC. I think it was ignition (vs. glow) but I might be mistaken.

I'm guessing very few of these Offy 270 have been made, you should track down who the builder is and when it was finished and add a brass plaque to the box to honor the builder.

I spoke with Ron Colonna at the Cabin Fever Expo this past weekend and he told me about the book he published about 20 years ago titled: Building the 1/4 Scale 270 Offy: A Workshop Manual. He said that 15,000 copies were sold, but, he isn't selling the book or plans anymore. I've been searching to see if anyone has a copy sitting on the shelf that they would be willing to sell.
