wooden props (a 10x8 designed for a glow engine) are WAY stronger that your electric one
i have put one on my rimfire and it worked great problem is if you crash hard the prop wont break most of the time something else will. motor mount, engine shaft, ect
i think gws has 10x8

they work well and will bend a bit so they wont break as easily as fiberglass electric ones
however im not sure if they wil work w/ your engine seeing as i have never used one
pics would help
