COMMENTS: Do not attempt to run system outside of an airframe.
          Do not disassemble rotor or remove nose cone.
          Do not install ESC in tail cone.
          Do not disassemble or modify the unit. If unit becomes damaged
            return entire assembly to the factory for evaluation.
          Keep loose objects away from the inlet and tail pipe. Point tail pipe
            toward open area away from people or property when motor is running
          Inspect the fan system frequently. Return damaged unit to factory for
            repair.
          Keep hands away from spinning rotor. Never attempt to hold unit in
            hand with battery attached.
          It is highly recommended that EDF fans be used with inlet rings and
            or inlet ducting and mounting/installation ensures that no
            excessive pressure is applied to the outside housing.
