• Event Format: The event consists of three standard rounds, each with a maximum flight duration of 180 seconds. If needed, a flyoff round may be conducted, with a maximum duration of 300 seconds.

• Power Class: Competitors fly in the 2.5 N-sec (A) power class, applicable for both Seniors and Juniors.

• Scoring: The score is determined by summing up the duration of the three flights during the standard rounds. In case of a tie for medal positions, a flyoff round serves as a tiebreaker.

• Model Limit: Participants are allowed to enter a maximum of two models for the three standard rounds. An additional model may be entered for the flyoff round if necessary.

• S6A Model Requirements: Models must meet specific criteria, including a minimum length of 500 mm, a minimum diameter of 40mm for at least 50% of the length, and a maximum mass of 100 grams.

• Streamer Requirements: Streamers used in the event must adhere to certain guidelines. These include having a length-width ratio of no less than 10:1, being made of a single piece of material, and completely unfurling in flight.

• Challenges: Competitors face several challenges, including ensuring the reliability of their models in terms of boosts, ejection, and streamer deployment. Finding thermals or lift during flights is also crucial for achieving optimal durations.

• Vehicle Construction: Lightweight materials such as fiberglass or vellum are commonly used for airframes. Vacuum-formed plastic nose cones with foam core shoulders are typical, along with lightweight balsa wood or reinforced balsa fins.

• Streamer Construction: Streamers are usually made from aluminized mylar and must undergo specific creasing and folding techniques to ensure effective deployment and drag during recovery.

• Propulsion: European motors with 10.2mm diameter, offering higher thrust and shorter delay times, are preferred over US motors for optimal performance.

• Competition Strategy: Finding significant lift is essential for achieving maximum flight duration. Competitors must balance the timing of their launches, replacing streamers between flights for optimal performance, and being prepared for various contingencies during rounds.

• This overview covers all aspects of the S6 streamer duration event, providing insights into the format, requirements, challenges, and strategies involved.
