It is a very small modal that we build and fly.it is most important to learn about the this modal, it has every part which is in a real  and everyone rule work which works on aship.it is made from kind of light wood.

Towline free flight gliders, are towed to altitude by a person running pulling a line attached to the towhook the glider. ... The gliders are normally super sleek with tiny fuselages and long skinny wings. 

Control line (also called U-Control) is a simple and light way of controlling a flying model aircraft. The aircraft is connected to the operator by a pair of lines, attached to a handle, that work the elevator of the model. This allows the model to be controlled in the pitch axis. 

An electric aircraft is an aircraft powered by electric motors. Electricity may be supplied by a variety of methods including batteries, ground power cables, solar cells, ultracapacitors, fuel cells and power beaming.

Electrically powered model aircraft have been flown since the 1970s, with one unconfirmed report as early as 1957. They have since developed into small battery-powered unmanned aerial vehicles (UAV) or drones, which in the twenty-first century have become widely used for many purposes.

Although manned flights in a tethered helicopter go back to 1917 and in airships to the previous century, the first manned free flight by an electrically powered aeroplane was not made until 1973 and most manned electric aircraft today are still only experimental demonstrators. Between 2015 and 2016, Solar Impulse 2 completed a circumnavigation of the Earth using solar power.

A radio-controlled glider is a type of radio-controlled aircraft that normally does not have any form of propulsion. They are able to sustain continuous flight by exploiting the lift produced by slopes and thermals, controlled remotely from the ground with a transmitter. They can be constructed from a variety of materials, including wood, plastic, polymer foams, and composites, and can vary in wing loading from very light to relatively heavy, depending on their intended use.

International radio-controlled glider competitions are regulated by the Fédération Aéronautique Internationale (FAI) although many countries have their own national classes.

In its most basic sense, 3D flight is controlled flight beyond the stalls critical angle of attack (AoA, or alpha) aka post-stall. Because the model is stalled and has little natural airflow across its flight surfaces, most 3D maneuvers require very large control deflections to vector the propeller thrust and change the models attitude.

3D aerobatic flying is a typically performed by model aircraft which have been configured with a higher thrust-to-weight ratio of more than 1:1. In fixed wing aeroplanes large control surfaces assist the aircraft on performing radical maneuvers which allow the aircraft to turn in tighter than conventional turns. This is achieved by having larger control surfaces; rudder, ailerons, and elevator and having greater amounts of throw applied to these control surfaces.
