Well,I did it again. I bought the 67.5 inch Kiev which is supposed to be spot on for my engine and gear ratio. The last one was for the 100hp and and gave me much degraded performance so I sold it to a friend that had a 912ULS. The new prop is beautiful,turbine smooth and quiet. In fact a neighbor said there was a dramatic decrease in noise when I took off. Those are the good points (which is enough to keep it)Unfortunately, it is no better in performance then my Warp was. Oh well !
I had concidered the IVO cause the reports are good but it is too "butt ugly" for me and looks like it should be on a model airplane.
In reality, my plane has alot of drag and a small engine so perhaps I am expecting a bit much. More speed would be nice (cruise @ 5000 rpm is 90mph) but climb is better and more fun. I don't fly very far anyway.
There, I have just talked myself into liking my Kiev even more !
