Precision Magnetic Prop Balancer TOPQ5700 to balance the propellers this is a necessity on glow powered engines and should be done with electric models as well Using multiple battery packs for successive flights may cause the motor to become excessively hot thus causing damage Allow the motor to cool for at least 10 minutes between flights Motor Safety Precautions Failure to follow these safety precautions may result in severe injury to yourself and others Get help from an experienced pilot when learning to operate motors Use safety glasses when running motors Do not run the motor in an area of loose gravel or sand the propeller may throw such material in your face or eyes Keep your face and body as well as all spectators away from the path of the propeller as you start and run the motor Keep items such as these away from the prop loose clothing shirt sleeves ties scarfs long hair or loose objects pencils screw drivers that may fall out of shirt or jacket pockets into the prop The electric motor and motor battery used in the Slinger are very powerful and the spinning propeller has a lot of momentum therefore if you touch the propeller while it is spinning it may inflict severe injury Respect the motor and propeller for the damage they are capable of and take whatever precautions are necessary to avoid injury Always disconnect and remove the motor battery until you are ready to fly again and always m
