I'm glad you brought up missing body parts. The 3 times we have had people stick their fingers and arms in the props, it was the ice from our beer coolers that saved the parts for reattachment. Whenever the need comes up, I will do without my ice for another human being. Not only due we pack ice for the "just in case" but I carry all kinds of stuff to keep the blood off me and to stop the blood from gettin all over everthing. This is all for my fellow R/C'ers -Mike
