Built for NARTREK Bronze streamer and parachute duration flights. Estes shock cord was replaced with a Kevlar line tied to a fin and going up the outside of the body tube, allowing near-horizontal recovery. Estes streamer was replaced for duration flights with a wide pleated Mylar streamer and a Mylar chute. Rocket not painted until after duration flights.
For the second flight I cut about 30 cm off the length, and got about 43 seconds.
