I fly an Aeronca Chief that has a metal McCaully prop.  I have been thinking of going with a Sensinich Wood prop.  Any thoughts from the group to the pro's and con's?

Wood's lighter, but metal's (practically) maintenance free.  You have to regularly check the prop bolts, with a wood prop, and make sure you park the plane with the prop level if it's outside.

Where do you live Ron? Rain is a fact of life where I live on the Gulf Coast. I had a Luscombe with a wood prop and after about 100 hours it looked like it had been dragged behind a pickup truck. They make props out of metal for a reason. Sure, they are a few pounds heavier and wood props seem to be smoother. A prop strike with a wood prop could possibly save your crank.

I have a Hatz Biplane with both wood and metal props available. By the numbers (pitch and diameter) they are exactly the same. Flying characteristics are indistinguishable from one another on an airframe this slow. Wood is prettier but requires more care. Climate matters. The rest is up to you.  Lou W N83LW
