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!
Here is where I agree with everyone. [

I use MAS and APC props on all of my engines that are .61 and smaller for the price and durability.
For Engines that are over this size the Wooden ones are recommended. The point is simple, over this size there is so much torque with a ground strike you can bend or break the prop shaft and the wooden prop is cheaper than an engine.
Happy Landings
