    I dont think the wood propeller was a problem with protection on leading edge..
    But for sure ,i love more a composite prop....for weight ..

    Weight is relative. The R2800 is about the same weight as an O-200 but dont forget the R2800 is powerful and geared to swing big props which are ideal for hauling off float planes.

    I cant see the engine weight being an issue at all, on the other hand the fat guts on some of the pilots I see is more alarming to me!

    I hope to install one... maube suitable for Rebel.

    I can't imagine such engine on my Stylus (sort of heritage KitFox and Avid), probably too big. But, one never know.
