Everyone's been saying use the wood props first so if you hit the grass or whatever, the prop will break instead of stressing the engine or something else. [

IMHO that's nothing but a myth. A nylon prop touching the ground isn't going to put any stress on the engine. I've been flying for 10 years now and I've had plenty of prop strikes with nylon props and have never had any damage to the engine what so ever. If you want to use wood props for training them you'd better pick up about 30 or so of them.
