JCINTEXAS - This is my first Rossi. Used to use the Super Tigre G61ABC's. Those are kind of rare now. Using OS61FX's in other birds. Ross has an adapter to fit the OS61 muffler to it. I just took that adapter, mated it up to the Mac's muffler for the OS61FX.

I have a Vertigo II in the attic, and a few Phoenix V & VI's here. I have started on a V and another VI. I may just get that Vertigo down to build something different. The Phoenix with the Rossi has history.

Ed Cregger, I have some 11X7 and 11X8's, see what works.
