The first practical flying models took to the air at the starting of the 20th century. Develop with doing of these aircraft depended on technology. All flying models need to be constructed of light, strong materials to fly properly, and require some sort of power to accomplish flight.
Twisted rubber bands were an early form of lightweight and cheap power for model aircraft, and are still used today on safe bet free flight planes. As the models grew in size and weight, small gas engines became the preferred means of powering the vast majority of flying airplanes. Gas model engines furnish a abundance of power, but require strong and heavy airframe structures to handle motor vibration, generate an oily mess from the machine exhaust, and the engines are quite loud.
ELECTRIC
Over the past five years, electric motors have undoubtedly taken over as the preferred power source for model airplanes. A fortunate convergence of technologies - small, lightweight and cheap radio control systems, sufficient rechargeable batteries and advanced brushless electric motors - have combined to revolutionize the model airplane hobby. Many of today's radio control aircraft modelers have flown nothing but electric Rc planes, and have never even started a small gas engine.
This trend favoring the electric Rc plane is likely to continue. Once exposed to electric Rc plane flight, the advantages come to be very clear over gas engines. Gas engines require a lot of support. Fresh fuel, electric glow plug igniters, electric starters and batteries, plus a wide variety of tools all must be on hand. It is not uncommon to see modelers spending the majority of their day at a flying field working to get a balky gas machine started.
Starting an electric Rc airplane poses no such challenges. Flight batteries can be fully recharged prior to arriving at the flying field. The model airplane pilot undoubtedly turns on a switch for instant, silent power from the electric Rc plane motor. While flying, there is never the worry of an machine failure so coarse to gas fueled flight; the electric motors have no challenging parts other that the prop shaft, and will run as long as there is battery power.
As an added advantage of electric Rc plane flight is the quiet power provided by the electric motor. Flying fields for gas powered models are becoming harder and harder to keep, as addition urbanization leads to more and more noise complaints. machine noise is an extremely important issue for the future of the hobby. Noise complaints can lead to the rapid closure of a flying field. Electric Rc flight wholly bypasses these concerns, as you naturally cannot hear the smaller electric Rc motors in flight.
In fact, these smaller electric Rc modeler groups earned the new nicknames of park or backyard flyers. For the first time in the history of radio control airplane flight, whatever can fly their electric Rc airplanes in their back yard, or over the street at a local park. Neighbors will not even hear the small, silent electric motors powering these aircraft. Without the need to bring along the general gas machine preserve equipment, the electric Rc pilot is airborne in minutes, and ordinarily within walking distance of his or her home. An added advantage of this spontaneous flight action in the local neighborhood is increased exposure of this fantastic hobby to a wider cross section of potential future electric Rc hobbyists. You could well spark a life long interest in aviation to some young person viewing one of these aircraft in flight.
The hobby of flying an electric Rc airplane will only continue to grow. Electric motors are becoming more marvelous and less expensive, and the arrival of ready to fly electric model aircraft is important to yet added interest in these unique models.
