Although all the aviation airplanes models are not possible to build in realistic but the scientists are using aeromodeling to give it a possible replicate full-scale aircraft model. Its main purpose is to test the future aviation designs, to realize the limitaions of making a proposed aircraft. Normally remote controlled aircrafts are lighter (even lighter than the air) than the aviation aircrafts. It can also make as the heavier than the air (wing glider/sail plane), fixed-wing single or multiple, multiple engine or rotary wing aircraft (autogyros/ helicopters).
The most interesting thing for remote controlled airplanes builders is that they are capable of making a controllable mini aircraft that almost look like full scale original aircraft. For desigining a full scale aircraft one need to consider about detailed cockpit, operable cable connected flight control surfaces, fixing landing gear etc. But these need not to be considered as making remote controlled airplane.
Any types of propulsion is absent for the Gliders as they are unpowered. When designing gliders it should be keep in mind that flight will be sustained through exploitation of natural lift that is made from thermals or wind. Another popular and common way to provide energy to gliders is the dynamic soaring.
Jets are very expensive to construct. To power the jets engines micro turbine or ducted fan is used. Air frames are normally build with fiber glass and carbon fiber. To ensure rigidity of the airframe wooden spars are reinforced the whole body. Some jets have Kevlar fuel tank. In case of RC jet aircraft electric motor is used instead of driven deducted fan to supply the power of aircraft engine. Here a smaller size EDF model is used. If propeller driven remote control electric powered aircraft is used then it is essential to use the same electronic speed controller and rechargeable battery.
Racers are small propeller driven aircraft. It is used for racing around 2, 3, or 4 pylon track. That is why they are also known as pylon racers. Different types of aircrafts are raced across the world, those flown primarily in the United States are; Q500 (424 or ARPRA) and Q40 etc. Its wings are normally made as light in weight and internal constructions are made of inexpensive materials and also keep importance on its peerformance at the same time. Its range of speed is depend on the contruction principle.
Remote controlled helicopters are sometimes grouped with the RC planes. Some RC helicopters have video cameras and are used for surveillance. Nowadays 3D RC helicopters are also used which can frequently changes its blade’s direction by creating a reverse in thrust.
Nowadays various toy class RC planes, helicopters and ornithopters have been seen on toy store shelves. All of them are made with some common principles. Proportional throttle and Lithium polymer batteries are used for light weight and long time flight. Expanded Polypropylene also used for better construction. Stable spiral mode helps in simple turning control and their low flying speed and rear-mounted propeller ensure safety when crushing into people and property.
