I was thinking of puting an OS on my plane because I can go to my local hobby shop and pick one up with a tuned pipe.
My preference would be the Rossi 53, but Morris is out of them and I have to order it. The Rossi is 15 ounces and may will hurt the aerobatic performance some. I would like to talk to someone who is running the Rossi too.

I've not flown my Magic with a "tuned pipe". Before I put the OS46SF on it, I had an OS46FX with the Tower Muffler.
The OS46FX with the Tower Muffler allowed the motor to spool up faster with the 12.25 x 3.75 APC prop. This allowed for decent vertical performance.
I could not use that prop with the OS46SF with standard muffler and had to drop down to a 11.5 x 4 APC prop.
