All,

I am in the early stages of building a Top-Flite Cessna 182 and am trying to make up my mind on the engine to use. I have a SuperTigre G75 new in box and thought I'd use it but Top-Flite / Tower seem unable to supply the incowl muffler and header for it.

I also have a new-ish OS 91FS w pump in my Spacewalker (which I fly a lot) but am loathed to remove it, even though I could probably bolt the G75 in there to replace it.

Lastly, I have an OS 1.20FS w pump in my Stearman (which I hardly ever fly). I do wonder though it a 120 wouldn't be somewhat excessive for the Cessna.

Since I'm building the Cessna as scale as I can, I don't want to have to cut the cowl for a protruding engine head or mufflers.

Choices, choices, choices ............

Any suggestions?

A Slimline Pitts would have to fit with the 75, unless you have some other problem with it.

I have a 1.20 in my Cessna, only the valve cover protrudes from the cowl. My Cessna is mostly for float flying so the 1.20 is not overkill if you ask me.

Top-Flites incowl muffler turned out to be too restrictive for the .75 size engine. Worked OK with a .60.
I used an OS.91 Surpass in mine and it was perfect.

Hi Terry,

Was the exhaust port too restrictive?
