 and common sense. Failure to operate this model in a safe and responsible manner could result in personal and/or property damage. It is 
your responsibility to see that the instructions are followed and precautions adhered to. The 8IGHT RTR is not intended for use by children 
without direct adult supervision. Team Losi, Spektrum and Horizon Hobby shall not be liable for any loss or damages, whether direct,

Warnings
    Fuel is dangerous if handled carelessly.  Follow all directions and precautions on the fuel container.
    Keep fuel and all chemicals out of reach of children.
    Always keep the fuel container closed and never use around an open flame or while smoking.
    The exhaust emits poisonous carbon monoxide fumes. Always run the model in a well ventilated area and never attempt
    to run it indoors.
    The top of the engine and the exhaust pipe are extremely hot during and for a time after use. Use caution not to touch
     these parts, especially when refueling.
    The engine can be loud, especially when run in a confined area. If you find the noise objectionable, use ear protection.
    This model is controlled by a radio signal that is subject to interference from sources outside your control. Interference 
     can cause temporary loss of control so it is advisable to always keep a safety margin in all directions to avoid collisions.
    Always operate your model in an open area away from people and cars. The potential speed of this model can cause 
     injury or damage.
