Basic notes

• When you fly a drone in outdoors you must comply with laws and regulations in the country.
  
• With care to not hit around living things or other objects.
  
  Because Tello's torque of the propeller is powerful. So it's dangerous.
• With care the amount of the battery remaining.
  
  For example, if you want to flip, needs not less than 50%.
• With care Tello's internal temperature.
  
  It will be in high temperature faster than be in flight when be not in flight.
• Let fly Tello in the light spaces.
  
  Tello will probably be not smooth working where in a dim room. Because Tello's camera has a role as a sensor too.
• Check the attaching portion of the propellers before flight.
  
  If it's loosed, doesn't move or it coming off and a Tello's body will probably blow away to anywhere.
