Sunday was a beautiful day to launch in Western Oklahoma. A bunch of folks showed up, including a few students from a nearby university's physics club. (competition better watch out in the next Argonia Cup Challange!).
My two best launches were my Raspberry Ice (Fatboy rebuild) which went up on an E28 reload, and a Baby Bertha on a 3-B4-4 cluster. The Raspberry is a great flier. I'm glad I added baffles in the last rebuild! I just stuff an engine in one end and jam the chute in the other (it's hard to get the two mixed up). The BB flew straight and somewhat slowly. I could track it by eye until it was almost out of sight, then it layed over and ejected the streamer. Unfortunately, it landed on the runway. The BB fins are long, and the impact caused the balsa to split down the grain in several places. I'm not sure how I'll fix it: glue the splits with thin CA or paper over them. I think this is a perfect engine combo for this rocket! If someone wants to get into clusters, this would be hard to beat! OR says it went to a tad over 650 feet. This would make a great park flier with the streamer (about 12 feet of 2" crepe paper), but if you recover on a hard surface, a small chute (or larger chute with spill-hole) would be better (expect drift with chutes).
