I like wood, it looks nice, is light weight, is easy to work on and I have a Sterba 49 X 34 wood prop on my full scale Moni. But wet grass or rain drops are enough to eat a wood prop. Full scale wood props use either brass or fiberglass on the leading edge to make them more rain and dew tolerant but I've never seen this on an R/C prop and I have eaten the leading edges on a few on my Saito four stroke powered Goldberg Cub taking off in semi-high grass.

So for R/C I skip wood props and go for the improved durability and performance offerred by other materials. The only exception with this is with Piper Cub models which just look better on the ground with wood props.
