You never know what might happen at the field: last weekend, at an area fly-in, was flying my Eflite Beaver, had my spotter next to me on the flight line, when another pilot taxied his electric trainer out. As he ran it up to move out on the runway, the prop/collet flew off. Prop landed about 2' from me and my spotter! Higher rpm/closer taxi woulda been a lot more exciting for us! All fun and games until someone gets an eye poked out
