Brad has one on his EOM picture, mine is for the 049 size.

Thank you very much for publishing these photos, they are very useful.
I am now working on an airplane model, but as soon as I have time, I will try to make one of these accelerator rings.
I was thinking about trying for a .010 from Cox ... I like the idea and the challenge ... but ... I'll have to wait for his turn ... haha
Thanks friend Marleysky

Thanks Rene , i have never seen one of these and didn't quite get it from Brads EOM picture . What is the date on packaging ?

There is no date on the paperwork. The address used does not have a zip code, so it was before 1963.

I assume Valve bodies 1 and 2 have smaller exhaust slits relative to the cylinder to effectively remove any SPI.... and that would make sense to me....wish we had more cottage guys to make these after market parts

Just thought I'd add a photo of the
cute little box these gems came in.

Been there, done that

Very good work. Can be the Engine of the Month winner.

Amen. Is this set up designed to be coupled to tuned pipe or an oil deflector tube? ? I'd like to see it installed on a Tee Dee or a Space Hopper.

It was just a little experiment to see what can be done in order to keep the noise down. We have a muffler regulation (compulsory) at our field...

Final version has a music wire clip to keep the muffler on.
