On my experimental SC I used a 0-320 engine and prop off of a TriPacer. The prop is a cruise prop that I intended to get repitched to a climb prop. I have been getting airborne in right around 300 feet however (which is sufficient for me) and am averaging 115 mph (GPS average). I think I will leave it alone for now, but am wondering if anyone has any idea how much airspeed I would probably lose and how much more takeoff performance I would gain by having it pitched to a climb prop? thanks Joe
