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.
I flew the Yankee twice, for the B Streamer Duration contest. B6-4 both times, and the first time I used the new streamer I made last month, pleated Mylar about 6 by 120 cm. I got 50 seconds, not as good as some of my flights earlier in the year (with a similar but shorter streamer) but comparable to the last couple months.
