Default RE: what a differance a prop can make.
All,

Glad I found this discussion - my experience is only one-year and have flown only the OS 46AX engine. On my trainer and now on my US 40, I have always used a 11x6 prop. Just for testing, I threw a 12x4 apc on my US 40 last week and I love it. I have a Tower muffler on the ax and I tached 14,800, I then richened five clicks for flying. My concern - the engine is running hotter with the 12x4 than the 11x6. Is the 12x4 really too much prop or should I richen it more for cooling? Appreciate any advice! BTW - I have a WM Mach II with a OS 46ax and 11x6 prop and it hauls ... I'm frequently asked what kind of engine I have.
