Parachute Duration information & plans
Parachute Duration (PD) - Models for this event contain a Parachute for its recovery system method. The models must stay in one piece, not drop any parts. A big challenge of this event is to have a model that can contain a large parachute that can deploy reliably, in order to get a good duration. Some use small diameter models that boost pretty high, while other fliers use larger models that can contain and reliably deploy a larger parachute, at a tradeoff of altitude performance.

Parachute Duration Model Kits
Apogee Components
International Thermal Sailor 13mm for 1/2A to A power. Designed for FAI S3A, 40mm diameter body. A bit big for 1/2A but workable, especially if piston launched. With 32" thin plastic chute. Skill level 4. Check the 12-part video series on building this model, at the same link for the kit.
Blue Streak 18mm model that can be adapted for 13mm engines. Comes with a streamer, you need to provide your own chute.
Aerospace Specialty Products (ASP Rocketry)
13mm Parachute Duration Kit - 1/4A-A 13mm model with 15" 1/4 mil mylar chute
18mm Parachute Duration Kit - 1/2A to C sized model with 18 1/4 mil mylar chute
"Hang Time" 1/4 mil Mylar Competition Parachutes, and 1/4 mil Mylar canopies and 54 x 54" sheet.
Fliskits
Cougar 660 18mm motor model, which can be converted to fly on 13mm motors. Comes with Stremers for contest or sport flying, so will need to add your own chute for PD.
Estes Industries
Wizard - 18mm motor size kit with streamer recovery. For lower power (1/2A to A) Parachute Duration, can have a custom 13mm engine mont added to it, and use a parachute from another source or a homemade chute.
Plans List
ASTRE PD & SD Plans - Drawing for a basic design, 13mm version and 18mm version (note larger fin pattern), that can be used for PD or SD. For PD, might want to make it a bit longer.
13mm Design by Trip Barber - Plan for a 13mm model intended for Streamer Duration, which can be used for Parachute duration (make a bit longer such as 12")
Mark Talkington PD & SD Plans - Plans for an 18mm model that can be used for Parachute and Streamer Duration
