Hotliner
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:
- Sailplane with at least aileron and elevator control
- Electric motor
- Ability to climb at an angle of 70 degrees or more, usually vertical climbs.
Hotliners have been around since the early 1990s and became popular almost a decade later.
