Until recently, most small rc model supported by two-stroke engine, liquid fuel. Model electric power is very rare, because the excess weight of the system, and battery operation. However, electric RC airplanes have become commonplace, especially in a new model for the driver.
Current benefit from the reliability, comfort, low noise, low vibration, and cleaner way of working. Losses from the early low-power system with the weight. However, aircraft engines, modern electricity, combined with modern batteries, the performance of electric RC aircraft quickly.
In the most common brushed motor, has been achieved via the contact slide switch known as a brush. Brush this summer and get the clothes from time to time. In the brushless motor, the changes occur through the electronic speed control. This second type of engine and more expensive. With the advantage of free treatment and a better performance.
There are essentially three types of batteries in electric service for aircraft engines. They are nickel-cadmium (NC), Nickel-Metal Hydride (NiMH) and lithium polymer (LiPo). LiPo battery for easy application, but more expensive than NiMH or NiCad batteries.
Electric RC plane, including the type of performance gliders, the interior booklet, model, a model of aerobatics, and led the fan (Jet-type). Almost all types of RC models can now current. Even electric helicopter is now a reality. For beginners, the stable and slow to trainers.
