RC aircraft is an art and practice that evolves through various stages. From beginners to experts this art has various fascination.  Proceeding on the steps first comes the beginners. Par flyers and trainers are made for them. Glow plug engine, electric powered and sailplane aircraft are more of interest to experienced flyers. At the apex level, expert flyers an deal with pylon racers, autogyros, 3D aircraft etc.

           It basically acts as a passage for past to present and future in terms fR airraft building technologies. RC scale aircrafts find their use in replication of aircraft designs from the aviation history for the test f perspective aircrafts. These have various. Steerable airship LTA(lighter-than-air) or heavier than air fixed wing glider or rotary wing aircraft lie autogyros or helicopters. The concept behind RC scale aircraft is quite straightforward. And clear. For a proper prediction of future design or in that case any upcoming aircraft, we need a model to test upon. From world war1 till the present era all full sale aircrafts have been modelled as RC aircrafts. Developers for RC scale aircrafts focus on creation of a controllable and miniature model with almost no technical specifications lie a detailed cockpit, cable connected flight control surfaces, navigation lighting on the real time functioning, landing gears etc. Availability of RC gears in the market sine 1960s has deeply revolutionized the development of various scale sizes of RC scale aircrafts.

           In simple words, gliders are the planes that have no driving force of their own and what is quite commonly called as propulsion. Unpowered glider an sustain themselves in air through a mechanism of natural forces(lie wind an thermals)  hitting the slope. An advantage with gliders is that even a common shape glider an fly with the same speed as that of a similar sized electric powered aircraft.  Gliders usually tend towards slow flying. These aircrafts hold a physical specification of high aspect ratio. Aspect ratio is defined as the ratio of height to wing area. Among training aircrafts two and three channel gliders are quite popular. The reason behind their extensive usage is that they use only rudder control for steering and dihedral or polyhedral wing shape to automatically counteract rolling. If we club the effective wing size and speed envelope of a glider frame with an electric motor, it is possible to achieve long flight durations and high carrying capacity. This combination can also act as a path for flying at proper locations even with no wind and thermal.

There are still further classifications

These are the aircrafts built with the ambition of an aircraft with good stability, acrobatic ability and sustained vertical flights.

Similar to hot liners these have less extreme thrust capability.

            These are propeller driven aircrafts that can complete around 2,3 or 4 pylon tracks. Fascinatingly pylon racers can touch  a whooping speed of 150 miles per hour. The most advantageous fat of the racers are their economic approach. Supporting this fact,  $100 could suffice for materials with 500 square inches of wing area and 40 engines. Some examples of pylon racers are Q500(424 of ARPA and 428) and Q40.
