« on: February 10, 2011, 10:01:19 AM »
     I posted this in the open forum also, I am running a RO Jett 40 rear exhaust on a muffler and would like some suggestions on fuel ( % nitro and oil%) also what prop and didn't ask this but RPM and any other suggestions that you might have.
   Thanks a lot, Gil

To get this started: (from open forum)

Hi Gil,

Well my first suggestion is to set it up just like it was running a pipe.  Been told to do that with my PA's that I plan to use a can muffler on, so it seems it's all the same as far as set up. 

Then go from there.

I would ask Mike Haverly. He's running that engine/header muffler in his new Chizler. Prop looked like a Bolly, 3 blade, trimmed and pitched to suit. When he ran that engine on a pipe in his Ornamental Plus, the first prop that really worked well was an APC...11 x 4 or 11.5 x 4, but can't recall which.  Anyway, "favorite prop" tends to change from week to week...  H^^ Steve
