  1. Keep a first aid kit in your work shop, car, and at the field.
  2. Be sure your propeller is balanced before it is used.
  3. Be sure your propeller is properly secured before running up the engine or electric motor.
  4. Treat every propeller as if it may turn at any moment.
  5. Treat every propeller as if it will fail structurally at any moment.
  6. Keep all body parts clear of the propeller arc at all times. Use exaggerated motions to avoid the arc.
  7. Do not stand to the side of a rotating propeller.
  8. Remove the propeller from the (electric) motor whenever you are doing an ESC/motor setup.
  9. When testing your airplane for thrust be sure it is anchored securely and pointing away from you and any bystanders before you attach any power (battery) source. Remember, it may start at any moment.
  10. Be sure to properly secure your model with a tie-down or have a helper hold it before you start its engine or motor.
  11. Between hand-props, give glow and gas airplanes a firm tug to ensure that the tie-down is holding them securely so the model will not jumped forward after starting.
  12. When tuning your engine stay clear of the propeller arc. Preferably, tune the needles with the engine shut down.
  13. If available on your transmitter, use a throttle lock or kill function to avoid an unplanned application of throttle until you're ready to fly.
  14. Always tell spectators not to touch or move your model's propeller.
  15. Never, ever reuse a damaged propeller. The cost of an injury far outweighs the cost of a new propeller.
