In radio-controlled aircraft, a hotliner is a fast sailplane with an electric motor. The range of what is often described as a hotliner varies from a sailplane with ailerons to 7000 watt competition F5b planes. General characteristics of a hotliner are:
Hotliners have been around since the early 1990s and became popular almost a decade later.
The first hotliner was Hans-Dieter Levin's Aeronaut Sinus, described in a German magazine.[ citation needed ] Originally, hotliners were electric sailplanes with remotely controlled ailerons, capable of flying faster than the models of the period that only had rudder and elevator controls. Levin tested his Sinus with a Speed 600 motor and an 8x4.5?(diameter(inches)/pitch(incher per revolution)) prop and a 7 cell NiCad battery pack. In this configuration a climb at more than 70° was not possible. However, the term, hotliner, has since evolved to mean models with a fast climb rate. Aileron-equipped electric models which are not so fast are called warmliners.
Typically hotliners are launched at full throttle and reach a high altitude. From here the pilot cuts the motor and starts a series of maneuvers.

A model aircraft is a small unmanned aircraft and may be a replica of an existing or imaginary aircraft. Model aircraft are divided into two basic groups: flying and non-flying. Non-flying models are also termed static, display, or shelf models.
A radio-controlled model is a model that is steerable with the use of radio control. All types of model vehicles have had RC systems installed in them, including cars, boats, planes, and even helicopters and scale railway locomotives.
Aircraft flight control surfaces are aerodynamic devices allowing a pilot to adjust and control the aircraft's flight attitude.
A radio-controlled aircraft is a small flying machine that is controlled remotely by an operator on the ground using a hand-held radio transmitter. The transmitter communicates with a receiver within the craft that sends signals to servomechanisms (servos) which move the control surfaces based on the position of joysticks on the transmitter. The control surfaces, in turn, affect the orientation of the plane.
F5b is a type of radio control electric model aircraft contest that consists of doing as many laps as possible between 2 poles 150 meters apart in 200 seconds followed by 10 minutes of thermalling, and then landing on a 30-meter landing circle. The laps must be made while gliding only, no motor allowed, so the motor is used to rapidly climb and power into the course. There is a limit of 10 climbs, so to get more than 20 laps the plane must climb high and glide 4 laps. To score more than 40 laps, the plane must glide a combination of 4 laps sets and 6 lap sets.
A radio-controlled helicopter is model aircraft which is distinct from a RC airplane because of the differences in construction, aerodynamics, and flight training. Several basic designs of RC helicopters exist, of which some are more maneuverable than others. The more maneuverable designs are often harder to fly, but benefit from greater aerobatic capabilities.
The Rolladen-Schneider LS8 is a Standard and 18 metre class single-seat glider developed by Rolladen-Schneider and in series production since 1995. Currently it is manufactured by DG Flugzeugbau.
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.
The Silent 2 Targa is a single seater sailplane of Italian manufacture. It is of the FAI DU Class glider. It is sold by Alisport ready-to-fly or kit-built as pure glider or self-launching glider. The self-launching version can be fitted with a single-blade propeller belt-driven by a two-stroke engine or with a double-blade folding propeller directly driven by an electric motor.
The Silent Club is a single seater sailplane of Italian manufacture. It is of the FAI type DU Class glider. It is sold by Alisport ready-to-fly or kit-built as pure glider or self-launching glider. The self-launching version is fitted with a single-blade propeller belt-driven by a two-stroke engine or optionally by an electric motor.
The term outrunner refers to a type of brushless DC electric motor primarily used in electrically propelled, radio-controlled model aircraft.
The UltraFlight Lazair is a family of Canadian designed and built twin-engine ultralight aircraft that were sold in kit form between 1979 and 1984.
The Curtiss No. 2, often known as the Reims Racer, was a racing aircraft built in the United States by Glenn Curtiss in 1909 to contest the Gordon Bennett Cup air race in Reims, France that year.
The Schweizer SGS 1-36 Sprite is a United States, single-seat, mid-wing glider built by Schweizer Aircraft of Elmira, New York.
The Slingsby T.9 King Kite is a British glider designed and built by Slingsby that first flew in 1937.
A glider or sailplane is a type of glider aircraft used in the leisure activity and sport of gliding. This unpowered aircraft can use naturally occurring currents of rising air in the atmosphere to gain altitude. Sailplanes are aerodynamically streamlined and so can fly a significant distance forward for a small decrease in altitude.
3D Aerobatics or 3D flying is a form of flying using flying aircraft to perform specific aerial maneuvers. They are usually performed when the aircraft had been intentionally placed in a stalled position.
The Ruppert Archaeopteryx is a Swiss high-wing, pod-and-boom, single-seat, microlift glider that was designed by Roger Ruppert and is produced by Ruppert Composite GmbH.
The DFS Reiher was a single seat competition glider designed in Germany by Hans Jacobs and first flown in 1937. The type won the last two German Rhön gliding championships before the start of World War II. Six were factory produced.
The Oberlerchner Mg 19 Steinadler is an Erwin Musger designed two seat tandem trainer glider built in Austria and first flown in 1951. Several examples of this successful aircraft, which competed in the two seat class at two World Gliding Championships in the 1950s, were still flying in 2000.
