How Injuries Happen
The most common cause of model aircraft injuries is the loss of control of a radio-controlled airplane. The model hits someone or an engine catches fire, causing serious injuries. Being hit by a propeller, or by the rotor blades on a model helicopter, is another common injury. In the United States, radio-controlled model airplanes can't be flown near an airport because of the possibility of electronic interference with the control tower as well as Homeland Security issues. Since 2004, more sophisticated model aircraft have been manufactured, including ones that fly at low speeds and have rear-mounted propellers. These features help reduce injuries significantly if the planes crash into people or property.
How High
Since many radio-controlled airplanes and helicopters fly at high speeds, it is imperative that the person flying a model aircraft takes precautions to keep the aircraft no higher than 300 feet. Some models can fly much higher, but it is important that your model does not interfere with commercial flights. If you notice that your model is not working properly or you see an airliner nearby, land your model aircraft as soon as possible.
How Close
It is extremely important for the model operator and spectators to keep a safe distance while flying the aircraft, just in case there is a collision or an operational problem and the aircraft suddenly falls from the sky. Even this small object can create big injuries from a high falling speed. Never fly your model aircraft near an airport, especially in the paths of takeoffs and landings. Some airports are close to mountains or hills where model aircraft may not be visible until it is too late. Be aware of your surroundings and operate your model aircraft with respect and caution.
Insurance
It is a good idea to purchase radio-controlled aircraft insurance. If you or someone else is injured by your model airplane, the insurance will cover you or the other person. The insurance will also cover damages done to the plane.
Common Sense
Common sense and knowledge will keep you free from model aircraft injuries. Learn to maintain and fly your radio-controlled airplane properly by investing in a good instructor. Clubs and hobby shops can help you find the right person to teach you skills that will keep you and others safe.
