Just remember a wood prop will break easiest therefore possibly saving your shaft on your motor. It is a lot cheaper to replace a wood prop than it is a motor or motor shaft.
I've never heard of anyone bending a nitro engine shaft with a prop strike. I've had many prop strikes, and I've even dug .25 and .50 sized engines out of the dirt with no damage to the engine.
ditto, i dug my .46 evolution that i trained on from deep in the earth haha ~6" at most.. anyway, i was self taught and i went through probably 15 props in the training process! the crazy thing is, i still fly that .46 evolution on my piper cub and to tell you the truth i think it runs better than a .46 evolution that i just bought about 1 month ago! i know its not because of break in either because the newer one has about 3 gallons through it by now so it should be making the most power, but i don't think it is, next time i run it i will check the rpms on both..
as for what prop to use, i would recommend apc, they are cheap and you will notice a little improvement in your engine's performance! good luck!
