RE: Prop Question
Personally, I would never use a prop whose blades had been bent. The bending (and straightening) has weakened the blades. If a blade should fly off the prop, it instantly becomes a sharp-edged flying object that can embed itself in the nearest object. The that object happens to be, say, a person's eye, you will never forgive yourself. Besides, props are cheap.
