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.
