Yeah,its not going to matter which you use,but the plastic ones are alot better because the withstand alot more then wood. I started with wood because thats what the manual told me to get,but the second the hit the ground they "wood" fly into a million pieces. Once the guys at the field told me to get some master airscrew (black plastic) props....I broke alot less. But any prop of the right size will work just fine for you. Performance is the least of your concerns,not to mention you wouldnt notice any difference anyway. I'd also recommend a you buy a 10x6 and an 11x6 prop for that engine. Doubt you'll notice any difference between the two,but I run 10x6's on my .42 engine and your engine is a tad bigger so you might get away with an 11x6,but either will fly your plane great! Just keep an extra prop or two on hand for spares. Keep in mind if you try different size props,they "might" tend to change the tuning of your engine ever so slightly. And also keep in mind for later down the road that larger props make it harder to slow down for landing. I only put bigger props on if I always have to fly my plane at full throttle alot while swinging high rpms just for level flying. Larger props will tend to pull your plane through the air faster at lower rpms. You just dont want to put on a prop so large that it will not let you engine reach its rpm power curve.
