- 32.1 Scope
- Streamer Duration comprises eleven events open to single-stage entries that contain a single streamer as the only recovery device. The purpose of this competition is to achieve the longest flight duration time.
- 32.2 Streamer Specifications
- A streamer is a continuous plane of identical cloth, plastic film, or paper; has a length-to-width ration of 5:1 or greater; may be folded and/or creased; it may not be cut, slit, punched, and or perforated. The streamer and model must be connected by only a single line or cord, attached at the narrow end of the streamer. That end of the streamer may include a stiffener and/or a yoke if desired.
- 32.2.1 FAI Streamers
- For FAI class streamer duration, the streamer must have a length-to-width ratio of 10:1or greater. The cord attaching the streamer to the model may be attached to a loop of thread that is attached to each corner of the narrow end of the streamer.
- 32.3 Assembly
- Several pieces of material may be joined into a single streamer. All such joints must be parallel to the narrow axis of the streamer. All pieces of the streamer must consist of identical material.
- 32.4 Qualification
- Some portion of the streamer must protrude out of the entry and into the airflow to aid in recovery for the flight to be considered qualified.
- 32.5 Classes
- This event is divided into classes based on the permissible total impulse of the motor(s). The following classes of Streamer Duration are established.
